I was working with my Buff and decided to load a mild recoiling load for kids and women. The first load was 41gr of Imr-4198. It must have been position sensitive because I had some hangfires with standard primers. Magnum primers did not hangfire. Velocity was 1788fps on a chrony and recoil was mild with the 300gr Hornady Hp. But wait, I had some 5744 on hand and tried 38.8 gr of that powder with the 300 bullet and standard primers. Wow, consistent ignition and 1 hole groups at 100yds. I think the velocity should be about 1800. And I thought 5744 was just for cast bullets. Any of you guys tried 5744 with jacketed bullets? If not, I am glad to report that in my gun it works fine.
