[QUOTE="trebark, post: 968051, member: 19172"] You're right, many people are shooting 94grains of Retumbo in 300rum. My rifle would show pressure signs at 92. The best load was at 91grains. The way you find out if your rifle likes more than 91 grains is to simply try it. Whenever you get a pressure sign (ejector mark, flattened primer etc), just stop. Your top end is below that amount of powder. In terms of incremental changes, don't waste your time with .5grain changes. Go with 1grain changes as 1% of 90 is .9grains. So test 90, 91, 92, 93, 94. Then once you find the charge that seems to be working well, if you want to try a .5grain change just to see what it will do, give it a try. Will any of these increases in powder increase your accuracy? there's no way to know until you try. And yes, more powder = increase pressure and temperature which means more wear and tear on your barrel. Don't let it bother you though. You can burn up a barrel with 91 grains just as fast as you can with 94. The key is to not shoot in rapid succession. Shoot and let the barrel cool, then shoot again. How much time between shots? that's up to you and your barrel. I like to give it a couple minutes between shots with the big magnums. As for primers, I have no opinion nor evidence as to whether Remington primers are junk or not. Personally, I use CCI BR2 and/or Winchester WLR. [/QUOTE]
