I looked up some old data, none of which I have tried, it's straight out of the book:
250gr- 50 gr H4831 start to 53 gr max, velocity 2450, source- Barnes handout ( very old )
250gr- 51/ IMR 4831, = 2,232 fps- source- Handloaders Digest, 12th edition
46/W760 = 2089 fps
43.5/W748 = 2072 fps
50/H4350 = 2131fps
54/H4831 = 2450 fps
Author of the article reported "shtogun pattern groups"- 5=6" groups with most loads.
From the Woodleigh manual, 240 gr:
43/H 4350 = 2055 start to 46/H4350 = 2205
50/H4831SC = 2180 start to 53/H4831SC = 2335
55/H1000 = 2260 to 58/H1000 = 2370
50/R19 = 2220 to 53/R19 = 2350
48/R22 = 2130 to 53/R22 = 2380
They have data for Vhita Vouri powders as well if you want it. The Woodleigh manual says the 240 gr requires a minimum of 1-10" twist.
