Good Morning!
I've got a silly question and would like some guidance if possible. Here's the info:
Model 70 Win .25-06
H4831SC
Norma Brass trimmed to 2.484
WLR Primer
Berger 115 VLD
COAL -- 3.250
Forster FL Benchrest Sizer and Ultra Micrometer
I've followed what was posted in Bergers Load Recipe for the above combination. My rifle seemed to prefer the lower side in powder weight, 49 grains to be exact. Book specifies 48.5 - 54.3. I know I doing this backwards, but I was looking for my COAL/CBTO. I used a Hornady/Stoney point gauge and a dummy round that's been fire formed with a 115gn VLD. When using Bergers recommended jump off lands with 6 rounds each at:
-- 0.010 off lands
-- 0.050 off lands
-- 0.090 off lands
-- 0.130 off lands
Should I keep the same powder charge of 49.00 grains while doing this? I know the pressure will decrease the further I seat it out. Will this be an issue?
Second, a 0.010 jump, the bullet is really hanging out there. Not concerned about neck tension. Just curious if only half of the bullet journal is seated in neck.
Thanks for the help!
