Couple problems on marlin 795 after the range

So I finally went to the range after getting my midway BSA 6-24 tactical scope. Let me start by saying I love the scope and it works great. so much better trying to shoot at 100 yrds and being able to see clearly.

I Will include some pictures at the end of my post that might clear up some of the things I mention heere. My first problem deals with the scope mounts. On my last scope I used regular rings, and they didnt stand a chance on the puny dovetails. The scope moved back alot by the end of the day. Which was really frustrating. With the new scope I got a one piece ring specially made for high recoil and dovetails. I thought they would get the job done, but unfortunately they did not. I marked the dovetails at the beginning, and 5 hours later and 650 rounds, it moved back maybe just SLIGHTLY. Basically, I zeroed the rifle at 50 yards, and by the end of the day when I tried 50 yards again, i had to dial about 3 MOA 'down' to zero it. The only other variable is that there was some winds at the beginning of the day, and at the end of the day it was absolutely still. I am assuming at 50 yards though, wind wouldn't create that big of a difference, even if it was head on wind, and since it the scope did move, im contributing it to that.

Does anyone have any further suggestions on what to do to get the scope to not creep? The only option, I can think of is drilling the rifle. The mounts have a hole on the bottom where a screw can be put through, So I can imagine that I can drill through the top of the rifle and put a screw through guarantee it holds there. But I would just rather not drill the rifle and mess something up if I dont have to.

The second problem is an extreme amount of FTE's and some FTL's. Throughout the entire day I shot about 650 remington golden bullets, 100 federals and 30 CCI mini-mags. So Last time I went to the range I had this same problem, but right away. After doing some research I narrowed it down to the remingtons being junk and me oiling up the rifle to much when I cleaned it. So I cleaned the rifle meticulously and used small drop on the fingers of oil for the entire gun. For the first 200-300 rounds, I would get a FTE once every 40 rounds or so. I was OK with this, because the remingtons are dirt cheap so I get what I pay for. I did not get any failure to loads at this point. Then after 300 rounds is when the problems began. I would get FTL only on the first bullet in the mag once every 5-6 reloads, and I would get a FTE almost every single mag. The FTL if I caught it before firing, I would just have to pull the bolt back couple CM and itlet go and it would load it properly. So it would get stuck at an angle half way in the bore and halfway out. SO I tried shooting with the federals and they seemed SLIGHTLY better, but out of the 50 I still got 2-3 FTE and 1 FTL. And the mini mags I only shot 20 or so at this point, and I had a FTE as well. So is there something wrong with my rifle or did the better ammunition not help because the rifle was dirty already after 300 rounds of remington? After about 600 rounds, the FTE's actually got a little better , instead of one every mag, it went down to 4 out of 5, BUT instead of getting stuck every time in between the bullet and the roof of the rifle, it would just barely get stuck in bolt on its way out. Does this make any sense that it got better, or is it just random. Any suggestions or help would be great.. Should I clean out the rifle right now again, or do I need to let it 'break in' a little and thats why it started getting better.

Here is the mount I have, as you can see its pretty heavy duty:

Here is what I mean when I say the casing gets stuck between the new bullet and the rifle wall. I simulated these situations and didnt have any spent casings, so imaging the top bullet is the casing. It would be really jammed in there, and I would have to give ALOT of force with a flathead to get them out, because the bolt hitting it really force it in there.

Here is what I meant by the casing getting barely stuck on the bolt. Imagine the bullet is a casing, and you can see it is barely stuck in there.

Also, to be clear. The ejection mechanism on the bolt works perfectly when I do it by hand. it grabs the bullet and snaps it out perfectly. Lastly, out of 650 remingtons I had not one dud that failed to fire. So atleast thats good haha.

Sorry for the long post, but any help would be appreciated!

I would take the allen head screws out of your mount and put threadlocker on them so they don't rattle loose and then tighten them up good. I can't imagine any other reason for that solid looking one piece mount to move unless it wasnt tight enough. Here's some thread locker http://www.midwayusa.com/viewproduct/?productnumber=241171 you can also goto the auto parts store and get the blue loktight threadlocker. As far as the jamming issues are you using a good factory magazine or a crappy high capacity aftermarket one? I would also completely strip down the action and clean it out really really good. My 10/22 can accumulate a lot of gunk that you can't see when youre just doing a standard cleaning. But once you get the trigger group out you find some serious crud. Especially if you have been over oiling it, lot's of debris sticks to oil. I like dry lube for that reason. Also you could try rimfire ammo made for semi auto's like federal automatch. Good luck. Don't give up on it, stay after it and you will be happy when you get er all figured out.
 
I actually have the threadlocker and put it on the last cope, but forgot on this one! Checking the screws though, they seem tight so not sure if thats the problem. I wouldn't of thought I would have problems like this after getting that msasive mount!

I cleaned the rifle before before using it today. I didn't take apart the action, but used qtips and such to try and get everything. I would say that I cleaned it up pretty damn good. Would you be able to recommend a spray cleaner thats not corrosive or damaging to the rifles parts? Im sure that will get in all the cracks.

Also after more research I know that for the marlin 795 most the ejection problems come from the ejector wire not being aligned properly. Unfortunatly it looks like my brand new 795 does NOT have the same wire that is shown in all the pix. Its not a wire, but rather a solid metal piece! Here is a picture of it

There is a product I have seen called shooters choice action cleaner (for use in the action) in a spray can that is supposed to be safe for painted surfaces but I have never used it. I have used a lot of automotive brake and parts cleaner but it is really harsh and will take off spray paint and certain finishes if your are not careful. What weirds me out is how is that monster scope mount slipping? Hope you get er figured out man.
 
Since you said it is the mount creeping back, I've got to agree with the previous suggestions, threadlocker. Good luck, keep us posted with any positives or negatives.
 
I will put some thread locker on all the bolts, then tighten as hard as I can without feeling like I am breaking something. Then report back.

As for my other issues. I just took apart the rifle and noticed one small thing. The little metal piece that the firing pins loop goes around is a little off centered, so it sticks out ever so slightly on one side. I see a little trail on the inside wall of the rifle from what I think is the edge sticking out. Is this normal for a 795?

Here you can see it is just slightly depressed on one side.

Here you can see that it just slightly sticks out

heres a better angle to see how it sticks out just barely.

Marlin semi-autos are notorious for terrible performance and reliability. You need to run it with 500-1,000 rounds of good ammo (not bulk crap), before you know if you even have a decent rifle.

...That's not an empty statement, as you'll commonly see on forums like these. I do actually have quite a bit of experience with Marlin semi-autos. You're going to have to deal with the problems, while feeding it premium ammo, before you know if it's a lemon.
 
Timelinex-
I have a couple thousand rounds through my 759 without any of the feeding problems you're mentioning. So I can't offer any suggestions. If you don't find help here, you may wish to look for advice at the Marlin semi-auto forum at www.rimfirecentral.com. Good luck

Tell that to the 16 MILLION people that own Model 60's...
 
I'm gonna try buying bulk federal instead of remington, and I guess we will see from there. But I just hate changing one small thing at a time to see if it works. Since I go shooting once every week or two and it really puts a damper on the entire shooting day.

Seems like there are some people that buy there's and shoot remington their entire life and then come on here and admit that they have never cleaned their rifle and it works flawlessly. Has no-one figured out yet what the difference between the rifles are? Seems like with how old these rifles are, that someone would have figured it out by now. It must be the manufacturing tolerences , where the one has a .01mm thinner part works great, but the ones that are .01mm thicker have trouble.

Lastly, this is kinda important. I cleaned the entire rifle including tacking apart the action, with hoppe's 9 solvent. BUT I decided NOT to put any oil anywhere at all. Is this ok? Will I damage the rifle, or is that one of those things where it wears it away faster over ten's of years of use. The hoppe's solvent seems to have a slight slipperiness to itself as well compared to washing with water or something. I just want to know that my problem is for sure not stemming from too much oil

In your pics you have some hollow point ammo, have you tried Federal automatch or other ammo?
Might feed better.

I never cleaned my two 795s and never have had a FTF or FTE in over 10 years of use. Few thousand rounds between them. Have lubricated them but they have been trouble free for me.
 
Yes, I bought two federal bulk packs from walmart yesterday. One is the 550 pack of regular federals, and the other is the 325 pack of match federals. So we will see!

A couple of ideas.
Scope mount moving -
My scope rings also shifted and was cured by buying rings with dual cap screw dovetail clamps. Holds solid now. I would think your scope mount should also be adequate.

The photo looks like the paint on your receiver goes up into the rail dovetail surfaces. If that is the case, there is a chance that the paint is compressing under the scount mount clamps during firing cycles and allowing the scope mount to shift. It seems like it would be a good idea to clean off the paint in the dovetail joint and reclamp the scope mount metal to metal.

FTE-
Do you have more than one magazine? Does the FTE occur with all your magazines? Are you using Marlin factory mags?
 
Yea I bought a second magazine, both marlin, but they both cause the problem.

As far as the scope, I hope I have it fixed. I put loctite on all the screw's, I tightened everything as hard as I could , I put in the set screw to the point of stripping the bolt unfortunately, and I just put dabs of super glue behind it on the dovetail.
 
So I went to the range again! I used federal bulk HP(case of 550) and federal auto match(case of 325). In the entire day I had one FTE! So something I did definitely helped. I don't know if it was the lack of lube, the new ammo or cleaning the action thoroughly. I did have other problems though, with the federal bulk HP.

The first hour was extremely frustrating. First off the federal bulk would once a magazine not fully cycle. So what I mean is it would eject,load a new bullet but it must have not fully threw back the bolt because pressing the trigger did nothing. And it was dud's because the bullet didnt have any pin marks. That wasn't too bad thought because I just had to cycle it by hand and problem fixed. The frustrating part is that I was trying for an hour to zero my scope at 50 yards. No matter what I did it seemed to be off. I kept trying thinking that maybe I'm moving while shooting, or maybe the wind is gusting hardest when I shoot. But no matter what I did, I would get one or two to group near the center and then the others would fly off.

Finally I went to the auto match pack. These babies worked like a charm :cool: . I didn't have the cycle problem and I was finally able to zero the rifle and group them together. They didn't always group super nicely but that would probably be my fault not the bullets. I would even be able to fire rapidly all 10 bullets and not a hint of a problem. I know its common for the rifle to like one ammo but not another, but is it common for there to be this big of a difference? I thought I became a horrible shot and I messed up my gun to not cycle properly, until I tried the next pack. It sucks that I have to pay a little more for bullets then if my rifle worked with the cheapies, but like I said its deff worth not having the frustration.

The only problem I did have is FTL's on the first bullet for all the ammo. No matter which I used, I would have a FTL with the first bullet, where if I cocked the bolt back a little it would line up properly and I could close the bolt. Any suggestions?? This is ONLY on the first bullet in the mag, on both marlin brand mags.

To be honest I think that the remingtons still grouped slightly better, but Ill take cycling perfectly with no FTEs over a little tighter groups. I am guessing its from the better ballistic coefficient and higher muzzle velocity on them.

As for the scope, it worked perfectly and did not budge! So the combination of loctite,setting screws, and super glue did it. I didn't fully level up the crosshairs, so I will have to rotate them a little but that wasn't a big deal.
