Well I finally put together my Stevens 200 7mm RSAUM. Came out pretty nice and decide to work with 168 VLD's and H4350.
Specs:
24" Criterion barrel
7saum rem brass Full length
Berger 168 VLD Hunting
H4350 powder
Wolf LR Primer
Seated .010" off the lands 2.954" col
Shot 56grs to 60grs. at 100 meters
I got pressure signs around 59.2grs. very faint, but got ejector mark at 60.4 grs.
A= 56.0
B= 56.4
C=56.8
D=57.2
E=57.6
F=58.0
G=58.4
H=58.8
I=59.2
J=59.6 SLIGHT SWIPE ON BRASS/ PRIMERS GETTING FLAT
K=60.0 SAME AS ABOVE
L=60.4 EJECTOR MARK/ FLAT PRIMERS.
STOPPED...
letters F , G, and H share same poi,and under MOA. I didn't finish OCW and made a short cut. Found pressure and worked backwards form their. Letter E looks to be a scatter node. 59.2grs had more recoil and muzzle sound changed,maybe due over pressure?
Going to work around 58.0 to 58.8grs. as ocw.
