FWIW:
1898 Krag. 100 yards. All bullets using 17 gr of 2400.
Lyman 314299- sized to .311. 5".
Lyman 311281. 4"
Lee group buy 170gr FN- 3".
Who says Lee is junk!
For my next trick I'm doing a string with just this powder and mold- 5 shots at 15, 5 at 16, etc. up to 21 to see which groups best.
All were WQWW and 50/50 with gas checks.
