6 arc - 109 or 108 ELD M loads

[270quest]

Anyone have load data to share with this combo in a bolt rifle. Howa mini - 20" barrel. I know leverevolution and cfe223 are the velocity powders. Looking at varget for temp stability, but really would like to wring out what velocity I can. The 109 ELD M - if I can run it at 2700 FPS, puts up some very strong numbers out to 600 yards!

For those running Leverevolution - how temp unstable is it? As in, If I used it in temps from say 30-65 degrees at distances out to 600, would I see enough change to matter? Deer, Antelope, possibly elk size game.

I don’t think you would see much of a swing in a 35 degree variance in temp. Most guys who have issues are dealing with a much greater temperature range. You could work up a max load at 65 degrees, then throw 20 rounds in the freezer and haul them out to the range in a cooler on ice and shoot them through a chrono to check how big the velocity swing would be. I’m betting it would be acceptable, but I cannot speak from experience with the 6 ARC or leverrevolution powder.
