I have been shooting a 30 BR for a short time and reloading with 4198. Was wondering if anyone was using Accurate 5744. Or, any other powder other than 4198 ?
While I have not tried A5744 yet, I have used a fair amount of H-4227, with very pleasing results (a decent pile of "fake wood" ;D), @ MVs just short of 3K FPS. The temptation with the latter, is to, "put more in", as there is PLENTY of empty space! With the H4227, and 112 - 118 Gr. bullets, I can easily get in excess of 3150 FPS, however, above 2990 FPS, could never get the desired precision. When we first began messing with the 30 BRs, I either acquired, or, already had stashes of A-680; Win. 1680, H-4227, A5744, RL-7, N-130, H-322, N-133, and, H-4198 . . . for some reason, the A5744 is the only one I never tried.
Experience, with the specific LOTS of those powders, led me to relying on the H-4227, H-322(Extreme), or, the H-4198 - all of these have won many Grand Aggs. for me. Others have experienced different results. With a new barrel, it's a good idea to check several, as one may prove more consistent, or, just plain "better".
A couple of years ago, I was discussing the potential for A5744 with a fellow who had a stash of it, and also had/has
QuickLoad, so, he ran off some "data" - the [
QuickLoad] results looked VERY promising - for both pressure and velocity. He called back and informed me that it - the A 5744 - "shoots"! If you're an experienced wild-catter, start low, and work up, it's worth a trial: as listed on most burn-rate charts, it is both bulkier, and slightly "slower" than the H4227. But don't ever trust a burn-rate chart - they provide only a, general ["on the same block"] comparison!

Sorry, I do not have QL. RG
