RE: KRB7 Rolling block
I've had mine since June. It really likes a 250 gr. barnes expander on top of 110 gr. of 777. It's also shown promise with the few conicals I've shot through it. I found it very easy to clean. I just pop the whole action assembly out and hit it with brake cleaner. The double safety takes a bit to get use to, but I like it. It's just part of my shooting routine now.
