I calculated based on a 24 inch barrel.
That should work well for you.
Code:
Cartridge : .300 H.& H. Mag.
Bullet : .308, 180, Nosler AccuBond 54825
Useable Case Capaci: 73.703 grain H2O = 4.785 cm³
Cartridge O.A.L. L6: 3.568 inch = 90.63 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Alliant Reloder-16 *C *T
Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

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
