Did a bunch more testing the past 2 weeks. Here are the highlights:
450 grain bullet 1.00" long 2.320" OAL
650 grain bullet 1.325" long 2.320" OAL
CCI 250 Rifle primers
Top loads are all compressed
650 GRAIN BULLET LOADS
31.2 4198 650 grain 1102 FPS
33 4198 " " 1155 FPS
31 H322 " " 903
33 " " " 960
34.9 " " " 1024
36.7 BLC-2 " " 850 FPS 5 ES 1 SD
38.2 " " " 897
39.4 " " " 934 11 ES 2 SD
450 GRAIN BULLET LOADS
43.8 4198 450 Grain 1555
49.5 H322 " " 1380 10 ES 3 SD
51.5 " " " 1489
53.6 BLC-2 " " 1102 FPS
56.1 " " " 1276
57.5 " " " 1305
58.5 " " " 1337 9ES 3 SD
59.4 " " " 1360
Ball C2 is an excellent powder for uniformity with mild loads. Flows through a measure like water, of course. H335 would be good too, for a bit more velocity.
Tip: If you want a milder than full-pressure load (with ANY bullet) in the .500, set your powder measure to throw a volume of powder equal to the space in the case under whatever bullet you're using (100% loading density but not heavily compressed--hold a bullet next to a charged case and eyeball this) and use any powder 4198 or slower. In order, 4198, Accurate 2015, Reloder 7, Viht N134, 3031, Benchmark 1, N-201, H322, Benchmark 2, Accurate 2230, 4895, H335, BLC-2.
Need something between WC680 and 4198 speeds for optimum full power loads with long-nose bullets like the ones I design. Vihtavouri makes two such powders, but I don't have any and they're expensive.
