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.

I just worked up a load with leverevolution and the 108 for my 16". Pushing 2775 fps at 86f and 2749 fps at 48f.

I'll be sticking some in the freezer tomorrow and chronoing it at a few colder temps

Just chronoed 5 shots freshly loaded from components that have been sitting in a ~75f environment.



Went right out the door and chronoed all 5 with minimal time for ambient temps of 84f to effect anything. First shot from a cold bore was 2709 fps, next 4 averaged 2737 fps.



I'm now thinking that the previous rounds that I had set in the fridge for 15 min and temp gunned at 48f never had the time to cool all the way through. Just put 5 in the fridge and 5 in the freezer, ill let them set for 2 hours and then shoot. They should be at around 36f and -4f.

How much leverevolution you running? I just got my barrel in and figured id run a load of lever in some virgin brass to break it in.
