Thread: 22-250 Problems

    Default 22-250 Problems

    I have a Remington ADL 22-250. I had a gunsmisth cut the barrel down to 16 inches and make it into a ultra light carbine. I shot it for the first time today. I was shooting Remington 50 gr JHP I was getting just over 1in groups at 100 yards.

    Next I shot Winchester Supream 55gr balistic tips. they didnt ever get on the paper. I found their exit holes and it looks like the bullet was hitting sideways or tumbling.

    I'm assuming I wont be able to shoot anything over 55 grs out of this gun because of the 16 in barrel. I dont know the twist rate. I'm going to start handloading. Would a 40 or 45gr shoot better?

    Any advice would be great.

    Barrel length shouldn't effect bullet stabilization. I would beet you have a bur in your crown, it can cause bullets to tumble.

    Why such a short barrel on a 22/250? Seems a 223 would be a better candidate for a short barreled carbine.

    Speed will affect stabilization, as you won't get the same RPM's at a lower speed. So, if 55's were right on the bubble, shortening the barrel could have caused enough decrease in speed to make them not stabilize. That's what I'd suspect if you were getting round holes with the 50's, and it'd be hard to shoot a 1" group otherwise.

    I'd start reloading with 50's if it were me.

    You lost velocity and that means the bullet is not doing as many rpms. The bullet is not stabalizing. that is going to get worse as the bullet weight goes up. You have a gun that has slower twist rifling. Thats why the M16 went to a 1:7 twist from 1:12 when they went to the .62grn bullet. the previous bullet was 55grns.

    Whacking off the barrel of a rifle / cartridge combo that relies on velocity,,,is like putting coveralls on a Playboy model. You toss out all the obvious advantages.

    As much as I like that analogy... I'd just pick a bullet that works go on shooting stuff.

    You lose a little BC between say the 50 Vmax and 55 Vmax, but not much. (not really a fair comparison, as they are different designs). You wouldn't have been able to stabilize anything much heavier than that with a 26" 1-14 twist barrel anyway.

    Beautiful mental image....note to self: Keep barrel as long as possible!

    I think sometimes bearing surface can have an effect when twist is marginal too.

    In 222 Rem., 1-14" twist, 55 grain Sierra, the Flat Base bullets weren't great, but the BTs usually weren't even on the target at 100 yards. Bullets were the same length, and weight, but one had a BT and so a shorter bearing surface.

    That's what I attributed it too, anyways. I didn't see any other possibilities. ???
