[QUOTE="MagnumManiac, post: 2188539, member: 10755"] The only factory barrels I will re-chamber are new, if it’s been fired, I won’t do it. I have done 2 for myself with a perfect outcome on both. A Win Model 70 Classic Stainless in 375 H&H I bought specifically to re-chamber to 375 Weatherby, and my Sendero II in 7RM that I re-chambered to 7STW. I really like the parallel throat on the STW, being 1/2 a ‘thou over bullet diameter just works. I have used this on several cartridges now and it works for longer than a tapered leade. The primary barrel is a custom 29” 1:8” twist 264WM, the STW is just for laughs really, cuz I can’t stand the 7RM! Have had so many hunters in camp bragging about their 7RM and when I dump a deer with the 300 and their legs fall out from under them they STILL say, oh the 7’s shoot flatter!💩 Cheers. [/QUOTE]
