i finally got to try out some ladder test loads that i made up a while ago.
6.5 CM on 7-22-18, 81 degree's
147gr eld-m , lapua brass (new) , cci small rifle primers, H4350 powder, 26" browning long range stalker.
i only shot for velocity, not for grouping on paper at distance.
started at:
36.0 gr - 2436 FPS
36.3 2427
36.6 2426
36.9 2445
37.2 2465
37.5 2498
37.8 2539
38.1 2569
38.4 2556
38.7 2554
39.0 2552
39.3 2587
39.6 2623
39.9 2640
40.2 2642 - max load in book
this is my first foray into doing a different type of load testing. i've always loaded up a bunch of different loads and shot for groups.
now for my questions. i loaded up 2 of each charge, i only shot 1 set. i loaded up a few more charges above max book, as it looks like i was coming into another node. i was not seeing signs of high pressure or sticky bolt lift. should i shoot them?
i also was going to shoot the 2nd batch and see if i get the same results on a different day. is this common practice, or just run with what the data already showed?
