[QUOTE="tbrice23, post: 1148168, member: 59502"] Well, it looks like H1000 is going to be the powder for now. I tried Retumbo up to 68 gr with 150 vld and 215M and had one five shot group at about .6 at 67.4gr at 2960 fps, anything higher was over 1 moa at 200 yards. Today with H1000 from 66.0 to 67.0 gr grouped just over .5 moa at 200 yards 5 shot groups at 2960 to 3020 fps with 15 to 20 half value persistent winds. That's a wide window for an accuracy node. ( my 270 AI was laughing 150s at about 3150 +). I'm using a Weaver 3-15 ffp scope so it could be better with a higher magnification scope. I'm sure that once my brass is fully formed I can reach a higher velocity node and I will continue load development after my hunting trip. I only have one or two more range trips to narrow the powder charge and verification. But I definitely want to revisit Retumbo and try RL 26. [/QUOTE]
