[QUOTE="Lefty7mmstw, post: 842905, member: 48043"] So basically the hornady should take about 5 grains less powder to get to pressure then, eh? I thought az had a rather loose/worn throat to take those charges when I first heard his charges but he says in the 300 rum bbl life thread that barrel is a fresh re-chamber. It seems the bergers are just somewhat more slippery in the bore and a bit more powder hungry than the hornady and sierra pills I'm used to. I concur that 40 fps per grain is a good roundabouts and possibly closer to 30 fps per grain until you get a head of steam on the load. With rl50 I started at 90 grains with the 225 hdy at 2660 ~ fps and hit 2870 fps at 98 grains; my brother ran the load compression up and went to 102 grains and we were right at 3,000 fps with that. As to velocity with the 225 hdy and rl33, I haven't found the wall yet ( 3,000 fps @95 grains is still mild) and don't plan to at present as the rifle's starting to get a lot of rounds on her (bought used and [I]my[/I] round count is at least a few hundred) and the hornady bullet isn't in production until at least next year; I've only got three hundred to last me until then.
