180 scenars in 7 saum

[mpwolf]

Looking for a load using 180 scenars in 7 saum. Would like to use H1000, given it's rep for helping with barrel life. I'm not looking to get every last bit of velocity out of it. More interested in developing a load that feeds well out of the mag, and offers solid performance on steel at distance. Anybody got a good velocity node to look for?

Short action mags or long?

short- trued up 700, feeding from Alpha mags.

Your probably gonna run outta room for powder before you find pressure.
ADG brass
H1000 start at 60-61

R26 solves that problem.
Start at 58

Remington brass is probably roomier

I have a pile of R-P brass. I have run up to 64.5gr under a 180 VLD, without pressure. Scenars will take less I expect, given the bearing surface.

Ran a quick and dirty velocity ladder with H1000 and 180 ELDs and Scenars, in virgin R-P brass. 61-64gr in 0.5 gr increments. ELDs went from 2703-2812, with no dicernable node and Scenars went 2773-2829, with nodes at 62.5-63 (2783-2787fps ) and 63.5-64 (2826-2829fps). Neither hit pressure, and printed very similar groups.

Short or really new barrel?

24" barrel, and a very old lot of H1000. I suspect I'll run out of room in the case before I hit preasure with this lot.
