[QUOTE="Lefty7mmstw, post: 1016424, member: 48043"] the 7rem is not quite overbore enough to use the retumbo and similar powders in all instances. I've had to go with a good bit faster powder a few times in rifles that weren't behaving with slow burners when the cartridge wasn't overbore enough to really put a load on the powder with the given bullet weight. For example I had one 7rem up 'till last year that would puke on 7828 with 140 sierra's. The last three 7rems before that shot lights out with the combo and this rifle did too until the temp fell a bit; then she'd shoot around corners. I went to rl22 and she was a bit better; I ate 100 fps and went to 4064 and she went to 1/2 moa unless I screwed up... If you are using a but more bullet weight something like 4350 would likely be your friend. [/QUOTE]
