[QUOTE="yorke-1, post: 1952164, member: 11960"] Now that the 131 Blackjack bullet has been around for a while, what's the opinion so far? I'm bored with my current 7 SAUM and need to repurpose the action for a while as a distraction and I've been considering a 25 PRC since a buddy has an unused reamer sitting in his reamer pile. My concern is that setting up a gun for one specific bullet is always a bit of a gamble. I think my real concern is the bullet's ability to hold up to high RPMs. I know Blackjack recommends a 7.5" or even 8" twist in the higher velocity chamberings, but I'm curious if anyone is having good luck spinning the bullets over 330K RPMs. If I used a 7" twist, I could still try the 128gr Hammer Hunter, anything slower and it would be either the Blackjack or something in the 115 class if the 131 didn't work out.
