Improving the accuracy of a Remington 700

What is the best way to get better accuracy out of a Remington 700BDL in 300 Win.Mag.? The gun is already accurate but im looking to do a little better without spending an arm and a leg. I was thinking of glass bedding it but not sure if it will help this model or make it worse. And do Sims barrel deresonators really work?. The gun has already had a quality muzzle porting system installed and not sure where to go with it now. I dont hand load either so im shooting good custom factory ammo. Thanks in advance.:)

I have 3 words for you ... "reloads, reloads, reloads"!

I have a Remington .243 and as you say about your rifle, it was pretty dern accurate with factory loads but we began experimenting with reloads and got it down to about 1/4" groups at 100yds consistently. Before my father shot the barrel out of it, I could tag rabbits with it at about 300 yds no problem!
 
If you are not going to get into reloading, you will have to try several types of premium ammunition until you find one that your gun likes.
 
a trigger job might help. A lighter trigger pull will make it feel like an entirely new rifle and ought to help accuracy a little. It is not expensive to have a smith do a proper job for you and I can't recommend it enough. Making sure the action screws are tight is another good thing to check and costs nothing. I get mine about as tight as I can using only one hand but the smiths on board will surely tell you to use a gauge and set it to a particular, accurate pressure.
 
Remington 700 triggers are easily-adjustable by the user...no gunsmithing needed. If you're competent to read and follow simple instructions and turn three screws, then you're competent to adjust a Remmy 700 trigger.
 
I've read good things about David Tubbs' Fire Lapping system. It has bullets with grit, for lack of a better term, that lap your barrel. One report I read cited a roughly 35% increase in accuracy using the system. Not bad for $35.

I need to look into that! I have never heard of it before and it sounds like a good idea.

In your readings on it, did you come across anything warning of potential barrel damage resulting from the over-use or misuse of this system? Sounds to me like that may be a possible draw-back one needs to be aware of.
 
I personally would not fire lap a barrel on a rifle that shoots reasonably well already. That would be reserved for one that I could not get to group at all, as a last resort before replacing the barrel. The risk of damage or making accuracy worse is too great IMO to use it on one that just needs some minor tweaks. Since fire lapping is abrasive, you can certainly overdo it and damage the barrel.

Have you tried several different loadings in the rifle? If you're not reloading I'd suggest shooting as many different loadings as you can get your hands on, you're likely to find one or two that are clearly more accurate than the others. Free floating the barrel might help but might make it worse so be prepared to add some contact back to the fore end. It's always seemed to me that Remingtons liked a little forend pressure as often as not. Then I'd look into glass bedding next, if it's done properly I've yet to see it reduce accuracy.

Basically if the rifle shoots decent now you want to do small things, one at a time so you can see what works. Sometimes simply re-torquing the action screws makes a big difference.

Ifishsum is online now Report Post

I am not the one who posted this thread I just read about the barrel lapping and was interested to hear more. It does seem to me though to be something that one would want to very careful in using due to possible barrel damage.
 
Accuracy

Jim, It shoots around 2 1/2 - 3" @ 150yds and would like to get 2" and under.. The trigger is set at a crisp 2.75 lbs. I think that the Tubbs system is for new barrels that need to be broken in and it makes a quick job of it. They only used to be offered as bullets for reloading yourself and now their offered in a ready to go cartridge set. Cabela's shooting catalog has them in it. Everything is tight on this gun and have tried a few different ammo brands and weights. I dont handload because I dont have the knowledge or room for it. I know its better but never got into rifle reloading because it seems like alot involved with it so im stuck with factory ammo.
 
one more thing mike - you ABSOLUTELY sure you have all the copper cleaned out of it? I've cleaned to remove copper only to have it pointed out how much was still left in there.

"Sweets" makes a great solvent for this also but you have to use it BY THE DIRECTIONS or you can damage your barrel.

I would like to ask you a question. I am going to convert my Rem. 700 up from .243 to a larger caliber. I would prefer .308 however I am having a hard time finding a barrel I want in .308. There are however, tons of barrels that would be acceptable to me in .300 Win. mag.

I am wondering, how do you like that caliber with the 700? What are your experiences with it?

You won't, of course, be converting a .243 to .300 Win Mag, but I'm sure you already knew that. ;)

Well, I am no gunsmith but I after reading this post I did remember the "short-action" issue. LOL :rolleyes:
 
700

Sir
DO NOT fire lap that barrel, it removes metal and is reserved for pitted or otherwise problem barrels.
Make sure your barrel is free of fouling, invest in a good set of reloading tools and carefully begin handloading as has been suggested.
With the coming political problems you had BETTER handload. I look for the most stringent restrictions on gun owners.
I am no longer an FFL holder and no longer do customer work.
However there is at present no restriction on doing hobby work for yourself. I look for it though.
I feel that muzzleloading work will be possibly the only gun work that will not be persecuted. I feel the present problems we are facing come from Middle East terrorism which and WHO are interested in the destruction of our freedom and way of life. God have mercy on us if any of the present presidential candidates are elected. Obamma, or Clinton will be disasters for gun owners and McCain will have us at war with Iran and our young men WILL be there for 100 years. Nuf said.

I cannot tell you of the stress and foreboding which I have about the future of our way of life, those of us who love the rifled tube.
Out blessed veterans of our wars are dying off and the kinds of men we used to have, and actually do now, are going to be demeaned, devalued and our pioneer, goood clean way of life is in great jeapardy. When SAME SEX MARRIAGE ia authorized by a judge and people are rejoicing because of it, that sends a message about the tenor and morality at the very heart of this great nation,
When our President has to go to Saudi Arabia and kiss the ugly face of a ruler who is the home of 18 hijackers where have we gone. It is shameful and unAmericasn for us to cower in the face of our enemies. Vote for me for president and with some of you old BLUE EYED boys help we will get things in order in 6 months = and I am serious.

Sorry, I forgot to add that this barrel is already broken in by doing it the old way with 50 rounds and lots of patches and time. And I use the Gun slick copper out cleaner. It works great and has a chemical reaction that turns the patches blue with the copper deposits and when no copper left it comes out clean. Pretty cool stuff.
WYLDMAN, The 300 win mag is a great cartridge with lots of them out there. Its good for almost any large game animal except the dangerous catagory which I guess you could use it but theres alot better for that catagory with more punch. 300 win mag puts alot of energy at longer ranges and I got it for an elk and muley hunt I have planned this year. I had a quality muzzle brake installed and made a world of difference. It now kicks like a 243 instead of a mule.
I just went out and spent $300.00 in different ammo that I havnt shot yet and gonna try them all and see whats the best. So far its the Winchester XP3 and Hornady custom with both shooting around 3"@ 150yds. This is getting expensive and hope it works out without blowing thru it all so I can return some at least.(glad I know the sportshop owner)
Can anyone tell me if its a good idea to get the barrel crowned or if it could be done with a muzzle brake already on?
Harry, You have my vote and im with you.

Free float the barrel, glass bed and lighten the trigger

This took my 700bdl 7mm mag down to sub moa many times shooting 1 ragged hole. It shot from 2-3 inch groupings out of the box.......also for my gun, i tried several different factory loads, and the absolute best round for my rifle was the Federal Sierra Game Kings BTSP
