Up front, I have never seen him or this video before. I did watch the whole thing and tried to be objective. It is my opinion that the rifle he had built is a very nice rifle. I doubt anyone here would turn it down if it were given to them, I know would'nt. He also stated doing it over again he would go with a 24" barrel. This would be an improvement, personally I would go 26" on that platform, and 31" on my DTA. Infact I just may do one. I have loved the 220 Swift all my life, my Dad bought one in 1958. The data displayed on the video in the comparison was accurate, just not apple's to Apple's bullet wise. It was more a factory standard comparison. I definitely would not consider shooting that bear with it unless it was in defense, but it did kill the bear. Damage wise it did quite a lot, that's the main dislike with high speed 22's when lung shots are made, they destroy too much meet. However, with proper shot placement to the head / neck they are quite good killers on Deer sized game. I was just comparing the 22 CM to the Swift, and they are close enough to each-other capacity wise, and the CM brass is easier to get and arguably better designed, and will function in my DTA way better than my 223 WSSM does. (it's way too short to cycle properly) The thing is you must choose the bullet you want to use and then the twist to suit. Fast light 22's out to 400 yards are flat shooting fun and accurate! In any event, rifles are like golf clubs, choose the right one for the shot!
We are all in this together, we are all opinionated, and hopefully all willing to learn!
Enjoy your shooting, encourage others to, and tell everyone to VOTE!
