New Marlin 795 misfires

Hi guys!
I'm having misfire issues with my new Marlin 795ss, wondering if anyone has any advice/suggestions.
Here's my situation: New 795ss. First time out, I swabbed the bore, shot 100 cci mini mags copper jacket hollow point. 1 misfire, cleared the dud, next cartridge in line, misfire... pulled the mag, cleared the dud, re-insert mag...fired fine. Got home, stripped the gun, light cleaning, put away.
Yesterday fired 200 of the same round, got about 6 misfires, same problem. misfire cartridge has light strike print, compared to casings that fired. Next cartridge in line had 2 heavy lonfitudinal scratches and also didn't fire. Seemed like after I pull the mag, then clear the dud, the gun resumes normal operation. Happend on first round in mag and also in the middle of mag. Not sure what to do, I need this gun for appleseed this weekend.
I think I'm going to strip it again and give it heavy cleaning, then back to range and shoot 100 rounds through each mag (I have 4 mags) to see if it's a particular mag...
Really like the gun, super accurate for me, just need it to fire every time :)
Any advice/suggestions would be greatly appreciated!
Thanks!
 
Are yout putting any pressure on the mag with your hand or rest? That has been know to cause this type of problem. if the scratches are on the top of the round it sounds like the bolt is dragging of the round. Try to clean the magazine as well.

If you have some fine emery paper, you might try sanding down any sharp edges on the bottom of the bolt. That may alleviate any scratches in the top round of the magazine.

Also check the inside edges of the magazine lips for burrs or sharp edges.

For the misfire situation, try taking the bolt apart and cleaning the inside of it and the firing pin to make sure there aren't any metal filings in it. See if the firing pin strikes are relatively deep. If they're barely marking the cases and very wide, the pin nose should be narrowed somewhat.

Check the firing pin nose and see if it's wider than this ("). If so, you may want to sand the sides down a bit, but round the edges; don't leave sharp edges that can cut through the rim.

A rimfire firing pin nose should not strike the fold of the case rim, but be as high as the start of the rounded part. The bottom of the pin nose should be slightly more forward than the top.

With the bolt in an "uncocked" position, see if the firing pin protrudes at least half a rim thickness. If so, and the pin width is similar to other rifles that work fine, the problem could be either firing pin drag, due to friction, or excessive headspace.
 
I have a Marlin 983t that was misfiring quite a bit. I disassembled the bolt completely, cleaned the grese off it and put some oil on it instead. Re-installed the bolt while torquing the hammer spring a bit to give it more tension, it's firing fine now.

Now if only I can get the damn thing to feed and eject correctly I'll be happy.
 
I've been shooting mine (got two) for a few years (10?) and they just keep shooting - never a problem and really never clean them. When they seem dirty I'll clean them up a little with some ballistol but not much need to keep them going. It is the perfect gun for an Appleseed event.
