Anyone shooting the .375 350 gr SMK?

I have been lurking for quite a while and discovered in older threads that the 350 gr SMK is available through Cheytec. I was disappointed to find my 375 H and H's twist is too slow.

I have heard that the 375/408 cheytac uses a 1 in 11.5 but the "normal" sized cartridges will most likely need a 1 in 10 twist. This leads me to the details I would like to know.

If you have been shooting this bullet in any smaller cases I'd love to hear the details.

Im building a 375 chey tac,,,,Im ordering two barrels,,,the first barrel is a 1-11 twist, this will be for the 350 smk....Chey tac and others are shooting the 1--11.5 twist.

The 350 SMK was designed by chey tac specifically for the 1-11.5 twist. They commissioned Sierra to build these bullets. If you seach the threads here and on snipershide forum, you will see folks shooting the 350 smk with a much tighter twist than the 1--11.5. The 350 seems to be really forgiving. Kiby Allan used to build his 375 AM with 1--11.5, but on one of his threads he said he now building it in a 1-10 twist so it will also shoot some of the longer bullets.

Spend some time looking at some of the new longer solids weighing 370 to 420 graines with BC's that are said to be well over 1.2 and you might just get the bug for a real tight twist like a 1-8 or even tighter. When you run the numbers on these bullets it's simply staggering. GS makes these real long solids and ZA makes them as well and there are others like Rky mtn, Hooker, Lehigh, and the Preditor bullets. Hope I didn't confuse you, there are several new bullets comming out for the 375 and in time I think you will find that this caliber is the ultimate 1 mile gun. However, I'd never trade it for my edge.

Re: Anyone shooting the .375 350 gr SMK?

I have been trying some long range loads with that bullet in my 378 wby. I am very impressed with it. With some of the new high bc 375 bullets the 378 wby has become one of the best long range elk rifles. My 338-378 wby's are the only thing that can stay with it for delivering max power at long range. Unless you go up to the chey-tac case.

That bullet is very forgiving with regards to twist rates. It will do fine out of a 10 twist. I fired them out of an 8 twist and they did ok; however, I believe they were on the verge of coming apart.
