22mag help

I have been working on this for a while and need some input. I have a stainless marlin 25 in 22 magnum, when I first bought this gun about 7 years ago it shot Perfect, I pulled it out of the cabinet last year for the first time in about 3 years, and it shoots horrible,,, it will throw one high, then low , then to the side...etc it's like it has no consistency. I cleaned the bore, tried all different ammo. And put a new scope on it, does anyone have any other suggestions to try?

Re: 22mag help

There are so many things that affect accuracy with the 22 mag including ammo.

First I would make sure everything is tight including the bases. If the base screws were not put in with locktite they work loose.

Second I would free float the barrel then go to the range. I'd shoot a couple of different loads with the free float and see how it shoots.

If youíre not happy with it I'd pull the stock and try some pressure on the barrel. I usually use business cards between the forearm and the barrel. I fold them to make a shim. Try different thickness until you get groups you like.

If you find a combo that works then stick to it. Remember they can be ammo sensitive.

One other issue that sometimes affects rim fire rifles and that is the torque applied to stock screws. Some need less torque than others. Some need the front screw tight and the tang screw snug. The only way to know is to experiment.

There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.

Re: 22mag help

I had the same problem with a Marlin 22lr. Nothing I did made the groups tighten up. A 5 shot group would be the size of a pie plate at 50yds. Ended up selling it.

Remember, shoot straight and shoot often.
Good... Bad... I'm the guy with the gun.

Re: 22mag help

I have found that the marlin micro groove barrels tend to shoot the heavier bullets better. Mine with heavy bullets will shoot groups touching at 25 & 50 yards, but lighter bullets seem more like a shotgun pattern.

Re: 22mag help

If it was cleaned from the front instead of the back it could have a nick on the crown.
