Re: 375 SMK in hand today
I have some for testing in my 375 AX and 375 AM. I am not overly optomistic about their performance.
Like you said, very short baring surface and at the velocity I will be driving them to, I am a bit concerned. In the 375 AX, they should work well but not in the AM.
In talking with the head research man at Chey Tac about my opinion of them, the first thing I told him was that they needed to jump the bullet weight up to 375 grs. His reply was that is exactly what he wanted but Sierra said these were as heavy as they had the ability to make.
There have been some issues with these bullets in early testing and they are working on a new design with a heavier jacket. I assume from that that they were having bullet failure in flight.
Now looking forward to Richards heavy 375s more then ever when they get up and running, especially his Al. Tipped versions!!!
Got the same impression you did seeing the 350 gr SMK in 375 cal. I think they could have made the BT a bit less aggressive which would have helped in baring surface length as well and probably not dropped BC a huge amount.
I would be suprised if these bullets have a BC much over .600. That said, compared to what else is currently out there, that is a huge boost in ballistic performance for a 375 cal bullet with conventional lead core design.
