Load Development with Norma 203-B
LC 11 brass once fired - trimmed to 2.005, swaged on Dillon 600, chamfer and deburred.
Tula .7.62 Nato primer
175 SMK machine pulldown
A)Shot 6 series of shots
B)42.5 g, 42.8 g, 43.1 g.....10 rounds loaded to 2.215 and 10 rounds loaded to 2.285 so 60 rounds total.
C) Wanted to test jam vs. jump
D) Chamber OAL is 2.300 so I loaded .015 off the lands and 2.215 because that is the reading I got measuring bullet ogive to cartridge base from FGMM which is 2.800 COAL
E) Almost each group had 2 primers that did not ignite so I am blaming the reloader (myself) and that is why even though I loaded 10 rounds for each string the results may not show 10 shots fired.
65 degrees, 3000 ft altitude, 3 mph wind, bipod, no bag, 1:10 twist Bartelin Med Palma 26" with AAC 7.62 SDN Suppressor, 100 yards
43.1 grains loaded to 2.285 was the best out of all of them. 43.1 grains loaded to 2.215 was shitty. The target with 43.1 grains had all 10 rounds through that hole that can be covered by a quarter. Of course if you want to get really technical then my statement is false because of the flyer in the upper left but 9 out of 10 ain't bad. What's weird is I shot 10 rounds loaded with 42.5 grains @ 2.215 last weekend and the results were much better. What I noticed was that because some, and pretty much too many rounds were not igniting I was jerking the trigger back rather than applying an even amount of force because for some reason I thought maybe the pin would hit harder. All strings sucked ass today except for the very last.

Max load listed is 43.3 gains and there were zero pressure signs so I am going to try 43.3 loaded short and long.
