Once I find the most accurate load there then I start messing with the OAL. To start I will measure and just go .040" off the lands. Then once all other variables are taken care of I start on the OAL. the OAL is the last step in the process for me.
The 50 gr Vmax is what I was trying out. Used H335, H322 & BLC2 with starting points at 10% lower than max in .3 increments till max.
Had the best results with H322 from 22.7 to 24.2 grs. I know its a wide margine, most of it was probably my fault. Actually, I think 23.9 was my best.
I am now looking to "fine tune" using seating depth powder adjustment.
.040 of the lands? isnt that a lot? my lands measurement was 2.010
less .040 would be 1.97 at the ogive & 2.35 in OAL...way to long for a
Does 2.010 sound about right?
