I love to carry my 650 loaded with 2 rounds of 22mag shotshell and 4 rounds of 22wrf. I had been using the Winchester loading of the wrf round and find it both quiet(by comparison)and accurate. At the present time, I can only find the CCI loading of this round, and I am afraid to use it. I have read that it is loaded with a slightly larger jacketed bullet that could greatly increase pressure and become unsafe. Can anyone confirm or deny this theory? I love this little J frame and want to keep it forever!
