Ok, so I have a pile of parts to build a couple rifles out of and am undecided on calibers. I know for sure that I want to shoot heavy high BC bullets and in 6mm, 6.5mm, 7mm. Here is a list of my parts so far: 2 RSR repeaters with .308 boltfaces, 3 bartlein 5R barrels 7mm 1-9. 6.5mm 1-8.5, 6mm 1-8. KMW sentinel stock, Mcmillan A5 w/kmw loggerhead, 20moa surg bases for both, got a couple os rem triggers (thinking about a jackson), got a 5.5-22x50 and a 3.5-15x50 NF high speed zero stop scopes with npr1, NF rings. I hunt alot of coyotes and punch paper, like to do some long range hunting also. Any feedback would be greatly appreciated. Been thinking about 6.5 CM, 6.5x47 , 6x47, 6xc??? Just cant settle on a choice, would love to here you guys' ideas! Thanks
