[QUOTE="Outlaw6.0, post: 410798, member: 23486"] My rifle still has the factory 22-250 Barrel, so unfortunately the twist is too slow to stabilize the heavy high BC bullets. I ordered my 3-die set from Redding which was readily available, brass is Nosler 243 win, I use Fed 210M primers & started loading with a 40grn Sierra blitzking with Ramshot hunter, I was able so safely achieve 4600fps before showing pressure signs. I don't have the load data here in front of me but I started by utilizing 220 swift data & worked up from there if my memory recalls correctly. I have left both the blitzking & the Ramshot powder in favor of a Sierra 53gr Match bullet & am in the process of trying various powders for optimal accuracy. Velocity is always there but accuracy has been finicky at this point ~1moa to this point, of course @ +4000fps I can certainly understand why!! This is a new caliber to me as well, the gents i know are using a fast twist bbl with the Hornady 75gr A-Max With either Retumbo or RL-25, most are getting ~3500fps with this combo. I know this isn't much info to start with but I hope I can help you make your decision. [/QUOTE]
