Happy New Years to All,

I had a chance to shoot a friends 35 Rem Marlin, pre-cross bolt safety, today. The first shot went in the bullseye, second shot was 1 1/4 inches higher than the first, 3rd shot was 1 1/4 inches higher than the second, etc. In all, 5 shots strung vertically almost exactly one inch apart. Lateral spread between the first 5 shots was less than an inch.

It seems like this would be a fore stock problem, either bad fit, etc. The gun is 26 years old and has had 2 1/2 boxes of shells fired thru it in this time period ( I fired the 1/2 box today). It has been his dad's gun, and was carried alot but never fired at game. The action is very crisp, tight, feels brand new. I suspect it either needs breaking in, or some other easily remedied problem.

I need your thoughts and opinions on this one!

Thanks, Jimmy

First place to check is the buttstock. IF it is loose, will get vertical strings.

Send best place to check (and the most work) is the mag-tube/fore end assembly. Have seen some of the Marlins that have had the mag. tube fitted hard against the barren just at the reciever (you'll have to remove the forend to view it). It's ugly, but if you relieve the tube (and if you need to, relieve the barrel abit) what work you do will be hidden by the forend once you reattach it.

Barrel has either an end-cap or a mag.tube hanger that binds it to the barrel. Has to be strong enough to retain the tube/forened under recoil, so can't relieve this area much...but can try to equalize the pressure.

While you have to foe end off, may as well check for uneven bearing of the wood to the barrel.

the bad news is that some barrels are just going to "walk" no matter what you fiddle with.

Jimmy,
Was the rifle in question shot with a full magazine ? As each round is expended, this obviously makes for a lighter gun, hence, different points of impact for each shot. This can be even more exaggerated, depending on where the gun is rested on the sandbags, or type of object gun was rested on. Most leverguns shoot best with the gun rested as close to the action as possible. Also, if some other hard object was used instead of sandbags, this too, can exaggerate the POI.
I would try shooting the gun in question loaded one round at a time, sandbagged, near or on the action, if possible, and see how she makes out. Never overlook the obvious. Hope this helps out, and hope I didn't offend if this was already tried or thought of. Happy shootin'.
Jeff

Update on the 35 Rem Marlin

UPDATE-

I just finished taking the forestock off, and it was almost impossible to get out of the reciever and off of the barrel/magazine assembly. Also, the barrel band was so tight I barely could get it off after I took the screw out, the wood under it is very black and highly burnished... obviously way too tight to do the gun any good. Also, the front sling swivel hanger is a little too large and was putting alot of pressure between the barrel and mag assembly, not good either. I took a little wood out of the barrel channel along the front 2/3 of the stock, and will work on the barrel band issue next. The barrel is going to get a good cleaning with a copper solvent, and then reassembly for some more shots at a target tomorrow. I am going to leave the front sling swivel assembly off for now... It is obvious now where the problem lays, too many pressure points along that barrel and magazine, plus a very tight stock.

I'll keep you all posted on my progress.

Consider that something has to keep that forend in place during recoil, so don't overdo the job.

One other bit of advice, which has held true for all two-piece stocks: where you put the front bag (if shooting off a bench) makes a difference. Isn't nearly as noticable on one-piece stocks (and most times isn't a factor at all) but with two piece stocks, trying the bag close to the reciever may help a bit...at least it has on some of the ones I've shot.

Exactly why this happens I can't say...but that fore end is linked to the barrel, and pressure on it is transmitted to the barrel...so where you place the bag seems to be more important.
