I mounted a Leupold vx-lll 2.5-8x36 on it and I really do like this rifle. I have some components on the way so I can't wait to try out some reloads.
Mule Deer, aka John Barsness, has published some excellent 375 H&H loads. Well worth trying some of his!
A favorite of mine:
260 gr Nosler Accubond
69 gr Reloader 15
Federal 215 magnum primer
Turns up about 2650 fps with excellent accuracy. That's a load John has published several times.
For the heavier 300 gr bullets I use H4350 with good results.
Looking forward to your range and hunt reports!
