[QUOTE="Veteran, post: 2928757, member: 118038"] OK, Here's some data shooting light weight 150 grain bullets from .300 WM. Hot off the press using my brand new Garmin Zero C-1 Chronograph. TC-Encore breech loader single shot, 28 inch bbl. [B]Powder Staball HD[/B] 300 WM 150 grain Sierra Gameking #2125 COAL: 3.461 Federal 215 Primers Peterson .300 WM long Brass 80 grains - 3074.6 fps 81 grains- 3135.8 fps 82 grains- 3166.2 fps 83 grains- 3180.6 fps 84 grains- 3262.5 fps 85 grains- 3293.6 fps I studied the burn rates for Retumbo and Staball HD, some Retumbo loads, in QL, and was comfortable working up 1 grain at a time monitoring my velocities as I shot. I never saw anything velocity wise, or primer or extraction wise that gave me any worries. I wouldn't advise doing this a grain at a time without a lot of data and velocity monitoring from a low starting base. I normally shoot at about 3250 fps in this rifle with other powders and the 150 gr Sierras, so this was as much velocity as I needed to see. Could have probably gone into the 3300's easily. Don't go shooting the heavy bullets using this much Staball HD. You'll blow up. The 85 grains is approaching a compressed load or 100% fill in the Peterson longs. What I was really impressed with was the stats for shooting 152 grain hammer hunters using Staball HD [B]Powder Staball HD--All shot at 82 grains.[/B] 300 WM 152 grain Hammer Hunters COAL: 3.461 Federal 215 Primers Peterson .300 WM long Brass 82 grains -3225.7 fps 82 grains- 3222.2 fps 82 grains- 3224.7 fps It was only 3 rounds, but ES was 3.5 and Standard Dev was 1.8 Have to shoot 20-30 rounds and see if this holds.....
