For magnum revolver rounds, I've been loading with W296 (currently have H-110) since 1985 and it is without a doubt a stellar propellant for the application. But as most know, it doesn't download well. So I have also been de-tuning a bit for my revolvers, using 2400, in these later years of mine (recoil isn't as exciting as it used to be).
I have 357 Magnum revolvers in 3", 4", 6", & 8-3/8" bbls. I also have a Henry rifle, 16" bbl.
I have 44 Magnum revolvers in 5", & 8-3/8". I also have a Marlin rifle, 20" bbl.
So as you can see, I have a lot of barrel lengths for which to load ammo.
As already mentioned, I have been using 2400 quite a bit these days, reserving the W296 almost entirely for the rifles.
For this thread, we really only need to talk about 158gn jacketed bullets. I've seen 300-MP around for years and just kind of figured it's more or less 2400 on steroids. Just my guess. But for about a year now, I told myself if I ever cross paths with 300-MP, I'll grab myself a # of it just to try out. During this latest shortage, as powders have been coming back on the shelves, I couldn't help but notice that Alliant products have been conspicuously missing - until yesterday. Yesterday, I poked my head into the Sportsmen's here in Twin Falls and they had a few Alliant products. There was Power Pistol, Unique, an 8# container of Bullseye (would have grabbed if I wasn't sitting on 10#'s of W231), and a couple others that I now fail to remember (I think AR Comp and Herco??). Anyway, there was also (2)#'s of 300-MP, so I grabbed a #.
My thought is for use in the rifles; save for a few rounds through the revolvers for the novelty of it. But definitely the loads will be tailored for the lever-actions. (Side note: If I crossed paths with Hornady's 180 XTP's, I definitely snag a box or 4.)
My Henry has a diet of only Everglades's 158 JSP's, with an amount of W296 that I believe slightly exceeds current published data, so I side-step the charge weight. It chronos at 1799 through the Henry, and 1270 through my 4" 686. At any rate, that is the only load I feed my Henry.
But now that I have 300-MP, I'm going to give 'er a try. And the Marlin 44 Mag too. I'm in no hurry as I, A): have lots of other load testing irons in the fire - if it ever gets warm enough to get to the range. And B): I have lots of ammo already loaded for my rifles, especially the Henry. (Off topic, but that Henry is sure fun to shoot - I just love it.)
So I am curious what other folks have experienced with 300-MP. I couldn't help but notice that there isn't much load data for it, but that doesn't really concern me much. Hornady has data; as well as Alliant's site. It's not a lot, but it's enough to get a work up started. I mostly just want to know what other people's experience with is has been.
Thanks in advance. - Nick.
