I did some chronographing with my 1894 classic 25-20 yesterday and thought I would share the results. Fired 5 shots per load, temp. 40 degrees. Please excuse the jacketed loads.
86gr remington softpoint-12grs Reloader 7
Average = 1669fps
High = 1747fps
low = 1626 fps
ES = 121.1
75gr Speer flatpoint-12grs IMR 4198
Average = 1692fps
High = 1713fps
low = 1681fps
ES = 31.4
60gr Hornady flatpoint-15gr Data 68
Average = 1907
High = 1920
low = 1900
ES = 20.4
75gr hornady holowpoint(loaded singleshot) - 14gr Data 68
Average = 1729
High = 1731
low = 1726
ES = 4.6!!!
85gr Lyman cast WW - 11.5gr IMR 4198
Average = 1626
High = 1666
low = 1571
ES = 94.7
80 gr lee GB - 2.7gr Unique
928fps
80 gr lee GB - 6.gr IMR 4227
1133fps
Looks like Data 68 is pretty darn consistent in this case, might replace 4198 as my go to powder for the 25-20.
