Bowling Pin Thump Question

I think both calibers, 44 Spl & 45 ACP will top out at around 5.0 grains of Bullseye at best with 250 gr bullets. 4.0 to 4.5 may be more practical for the ACP at that weight. Personally, I don't use 44 Spl cases in 44 magnums, my current favorite light load is a 250 Keith (RCBS or H&G 503) with 6.0 gr of Red Dot in 44 magnum cases. This is good for around 850 FPS. My goal is around 900 fps for light 44 mag loads. I use 5.0 gr of Bullseye in 45 ACP with a 230 gr LBT LFN that I cast myself. I don't know the velocity, but I do know there is a lot more room for power in my 1911s than using this combination, but I haven't felt the need for it yet. Honestly, I rarely use Bullseye, preferring slightly slower powders for the lighter loads.
