Looking for input on best reamer specs for the new Norma 284 Winchester brass. Our loaded ( 180 Berger Hybrids ) no turn necks are right at .3155/.3160 and web area is running .498 . COAL is at 3.240.Have one of PTG's prints #54201 but think this is for the necked up 6.5 x284 Lapua brass. Any favorite numbers for this reamer?
