[QUOTE="RockyMtnMT, post: 995289, member: 7999"] Ok, I think we may have this thin figured out. We had to scrap the US-869, it was giving huge pressure swings with small temp increases. Settled today on Retumbo. Have burnt a lot of powder the last couple of weeks to figure this girl out. Running 90g to push the 130 to 3850fps. Not nearly as sexy sounding as before but still pretty impressive. At that speed the .63bc still looks good to 1070yrds. Will be able to work that out a little better at the next session. Wind was a bit tricky today but was able to shoot consistent 4" groups at 635yrds and shot about 8" at 1070yrds. No more powders this year, but would really like to try Ramshot Magnum if it ever comes available. Over all feeling pretty good about how the day went. Should be able to go out next time and just fine tune drops and get ready for the soon to come hunting season. Steve [/QUOTE]
