Ruger single six- problem with 22 mag tumbling

[airslot]

I recently picked up an unfired Ruger single six 22lr/22mag 6" in Stainless.

Took it to the range yesterday and had no problem with 22lr. Switched to 22mag and had the bullets tumbling into the target. Ammo was CCI Maxi-mag 40gr hp.

Anybody have any idea what might be causing this?

40 gr. Maxi Mag ammo usually runs fine in a Single Six convertible. It's a mystery to me, call Ruger. They'll fix it.

I'd try a couple of different brands of ammo before making it Ruger's problem. But if the problem persists with 3 or more different loads, then I'd say the evidence points to the gun.

If memory serves me correctly, the bullet diameter of the .22 mag is actually a snick larger then that of the LR, so your problem seems a little unusual. However, the bore diameter of the .22 mag cylinder may be oversized, which would allow the bullet to enter the forcing cone or the barrel slightly tipped. There is also a chance that the cylinder is mis-timed... that's supposed to be checked at the factory before shipping.

Thanks guys

I'm thinking it may be an ammo issue too. I have another box of CCI with a different lot# and some WW 30gr. I'll try them first then call Ruger if the problem persists.

Is your target mounted against a backing board? If not, it easily gives the appearance of a tumbling bullet.

Yes it was clipped to cardboard backer. I'm leaning toward an ammo issue since some made a nice neat hole. The ones that tumbled were all over the target.
