I've been checking the distance to the lands in my VTR (.308) with a Stoney Point gauge. I plan to load two different bullets (maybe).
Nosler 30150 150gr Sptizer (green tip)
Sierra 2130 150gr Spitzer Pro-Hunter
The Sierra's are no problem. The Sierra manual says C.O.A.L should be 2.750. I consistently get 2.894 to the lands with the Stoney Point gauge. I'm going to load them .020 off of the lands so I'll end up loading them 2.874 (.124 longer than the manual recommends and .064 longer than SAMMI max in the Nosler manual)
The Noslers haven't been so easy. The Nosler manual says the SAMMI max O.A.L. is 2.810. I consistently get 3.017 to the lands with the Stoney Point gauge. Sticking with .020 off of the lands I would normally load the bullet 2.997... that sems to be a long round for a .308. It's nearly a 1/4" longer than SAMMI max.
This is a new rifle and new caliber for me. I have been loading .270 and I've measured the distance to the lands a gillion times. I started with .020 off the lands in my .270 and it seems to be a good choice.
(A) Should I be worrying about the round being a little over 1/16th of an inch longer than SAMMI max (Sierra bullets / Nosler data) or just load it and shoot it?
(B) Should I forget loading the Noslers off of the lands and just go with the SAMMI max recommendation in the Nosler manual?
PS- for those that think that the VTR is ugly... put an HS Precision stock on it. It's purdy
with that stock. Kind of like a gun version of a boob job. I can't figure out why Remington put a Dollar General / Walmart stock on that gun...
