[QUOTE="208 TZR, post: 3069952, member: 14857"] I've got a 22" barrel as well. Shooting at an elevation of about 3700', at about 50-60* F. 66-68gr of Retumbo with 175gr Bergers is giving me about 2850fps, and 2850fps with 195's. The H1000 at 64gr with 175gr Bergers is only pushing about 2680-2700, and the 195's at 2750fps. Of course, temps aren't always identical...but Retumbo is giving me a little bit more juice with the same group results. I can easily hit 3k fps, but my groups go to hell when I do that. At least for my rifle, 64 gr H1000 and 68 gr Retumbo have been the sweet spot for groups, at the expense of some velocity. Consistently though, with a varying range of powder grains between H1000 and Retumbo, Retumbo is yielding better velocity than H1000. [/QUOTE]
