I was wondering about the strength of S&W .22 revolvers with the aluminum cylinder. Let me be really specific. Is it safe to shoot CCI Velocitors in the 317 and 43C? I am wanting to carry as potent a load as possible for use while hiking, and I have read superb reviews of the Velocitor, but I just don't want to ruin my gun in the process. One point to consider is that the 351C is virtually the same gun as the 43C, also with an aluminum cylinder, but chambered in .22 WMR. So, one could reason that if it is strong enough for the .22 WMR, it should be able to handle hot .22 LR. However, the 351C only holds 7 instead of 8 which means that the cylinder walls are thicker on the 351C, and I am sure that was done for a good reason. I am just thinking while I am typing. Any real world experience with these Air Lite .22s and Velocitors would be appreciated. Thanks!
