Re#22 or IMR 7828

Shooting 80gr Berger VLDs out of my 22-250AI 26" 5R 8"twist BBL 42.5 grs of Re #22 produces 3350 AVG 42.5 IMR 7828 produces 3325 AVG both about the same accuracy. 1 more gr of either powder will lock the bolt up.... So which powder should I use?

That is like asking if you should drive the Porsche or the Ferrari today.

Re: Re#22 or IMR 7828

My choice would be RL22 because of the extra velocity over the other powder, however small it maybe, and I just like RL22. As a matter of fact I burnt 897 gns of it yesterday in my .300WinMag. I found an accurate load for the 180gn SMK (75.5gn/9.5M = .346"). JohnnyK.

Gosh, whichever one you have most of on hand I guess. You are very fortunate to be at the point of splitting hairs here.

I have very little experience with 7828 and really haven't used any in years. I probably load as much Re22 as any other powder combined, however.

I like the smaller kernels of Re22 powder, but I've not seen the latest 7828SSC either.

Why don't you just load a sh_t load of ammo using all of what you have in both powders?

Re: Re#22 or IMR 7828

Just back from the rifle range. Re#22 is the stuff. Narrow ED amd SD nice tight group . IMR 7828 with same powder charge as Re#22 ( 42.5) Produced 100 FPS ED out of 6 shots. Interesting how a BBL likes one powder over the other when their both slow burning powders? Why? Does it have to do with the harmonic's of the BBL ?
