Started developing some loads for upcoming 300 WM. Loading 165 Gr Nosler Ballistic Tips. First used 75 Gr RL 22, Next 80Gr H1000, and then 74Gr IMR 4831, all with Fed 215M Primers. Loaded 3 bullets each and shot for group. My best group was with H1000 @ 80Gr, .75" @ 100yds.
Has anyone else tweaked this load?

I haven't tweaked that load, I typically use the 180 A.B. Have you tried doing workup loads with this to find a sweet spot?

DKA,
That was the first bullet I tried in my .300WM right after I bought it, but have moved up to the 180gn Ballistic Tip. I shot the 165 BT for deer when I lived in NC and it performed great. I started out using the 150gn but it wouldn't stay together at the speeds the .300 can send 'em.
Anyway, for the 165's I used H4350 with a 9.5M primer. 71.0gns gave me 3244fps and .585", 72.0gn produced 3269fps and .4175", 73.0 was 3296fps and .6340". All loads showed ample velocity and accuracy. I shot the rest of the 165's I had with the 72.0gn load. Hope this helps. JohnnyK.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
