Hey fellows I'm new here and ran into this forum a couple weeks ago there's a ton of great information here. I simply need some good advice on the right reamer to go with. I'm building a grendel obviously on a new CZ 527 7.62x39 action picking it up tomorrow at buds I've got a 29" Bartlien blank I'm gonna have it finished at 27" my main goal with this rifle is to simply punch paper above all and I'm gonna stretch it out as far as possible on the range. So I'm looking for the right chamber to get me the absolute most out of this round without going to something like a grendel max. I want to be able to use standard brass and I plan on loading 123s and hopefully 130gr JLKs I would like to get to 1000yrds with the 130s. So I'll need all the powder I can get in her I'm sure but I need help with the pressures so that's where the chambering should help. But you guys know much more than me on this round so any help would be greatly appreciated. I would love to know what chambering Speedy Gonzalez is using on the grendel he has on 6mmBR.com the one he claims to be getting 2700fps out of the 130gr JLKs not sure I will achieve that but it would be nice to get close. Thanks for any help.
