[QUOTE="dwm, post: 31122, member: 1136"] 4mesh063, Retumbo shoots great in my 25-06, I see no reason it wouldn't shoot in his 6.5-06 Imp. I can get ~3150 fps with a 115 Nosler BT using 60 grains of Retumbo, 26" barrel. Nice little .3 to .5 MOA 5 shot groups too. I was under the impression that RL25 burn rate was almost the same as Retumbo, slower than H1000. Hodgdon puts out an Annual Manual that has load data for the 6.5-06 in it. Bought the manual from MidwayUSA for next to nothing. Has a lot of data in it. Manual lists H1000/142 gr Sierra HPBT starts at 49 gr and goes up to 55 compressed, maxes out at ~2816 fps with a 24" barrel. With the improved case he should be able to do a bit better than this .... [/QUOTE]
