That should work well for you.

Thank you. My rifle doesn’t like H4350 above about 2870 FPS. I have some 16 sitting around doing nothing so I thought I would try to reach that 2950 mark in case I can’t get anymore Rl 19 or 26.

RL16 looks pretty good in the 300 H&H Mag.
Definitely worth a try.

Nearly a full case with 100% burn and a tick under 3000 fps , can’t pass on that.

There is a whole other coolness factor to the 300H&H. An absolute classic in every respect.

I really enjoy the rifle. It shoots pretty good, better than me mostly. I got a .33 moa group at 300 yesterday. I struggled yesterday when I got off the bench and started shooting the 400 yard plate. I think I only hit it 4 out of 10 from kneeling.
I just finished loading up a box with 180 Accubonds and Partitions. We’ll see what happens on Wednesday
