This is the perfect thread I was looking for. I just saw that BHW Claw rifleing for the first time and I was just thinking of ordering one for my large shank savage. They sure dont give much info about the claw thing, the pictures looks like it could be just small geometry changes to their original 3P.
Ive got BHW 223 and it took me awhile to figure out good loads and what the differences of these poly twist are. Hahaha, mine shot 14moa with 53Vmax and CFE223, i switch to 53Vmax and Benchmark and all is well again.
Ive done a bit of testing with HBN lube recently for bullets and barrel, it seems to me the lube offers nearly the same benefits as the polytwist, stacked on top of each other and handloads can seemingly safely go off the charts. I got some HBN lubed 53 TSX with H322 behind a lab radar shooting 3330fps from 16" 1-8 BHW, thats screaming pretty good out of an AR carbine. And accuracy is fantastic with those. I had a few HBN lubed 65SGK and I was shooting them safe with a max compressed case full of Benchmark. CCI450 primers are good, I have had some split case necks but I havent annealed my 223 in 10 years and im just testing on the max side. I reloaded for a buddies 13.5" and 18" 6.8 SPC with BHW, i didnt experement as much with those but they showed the same signs. An AR15 in 6.8 with Barnes bullets and BHW barrel is a heck of a rifle I would trust it against nearly any animal in the woods.
Im getting a 22" inch BHW barrel in 260AI, I think i can get it to beat the 30" 260AI barrel on the action now. I see they only do the Claw rifling in .264 which is convenient for me but I dont see it available in the bolt action section, only 6.5 grendel and such, maybe AR10 6.5 creed but I forget, I need bolt action. Claw rifling, whatever it is, or not I think these poly twist are an awesome option for handloaders. If i was stuck with factory ammo I might change my mind, I havent tested it.
