I have had a new 992 22/22mag for a couple months now and finally got out to test it the other day and had some issues. The 22 lr seems to shoot just fine with about anything I put through it but the magnum sowed some interesting results. My favorite 22 mag load is the CCI 40 grain solid. When shooting these I noticed right away that the groups were horrible and upon inspection of the target i could see that the bullets were key holing so they must be tumbling. i put in a few other brands such as Hornady and Federal and the groups were decent. I'm thinking that maybe the four inch barrel will not stabilize the 40 gr solid bullet? Could I be on the right track? Any one else had this problem or have an explanation? Other that that I love the gun. Is there anyone else who actually makes a truly solid bullet in 22 mag that I could try?
