Closest sub for H4198/IMR4198

[DartonJager]

Now that it appears that there will never again be H4198 or IMR4198 available for sale, anyone know from experience if there is acceptable replacement powder. I will be using it in my .50 caliber Savage 10ML-II smokeless ML with 245, 250, 290, and 300 grain projectiles seated in a sabot.

Alliant RL-7 and Vihtavuori N120 should be close.

Benchmark is also very close, you may get similar results with 8208, but I am yet to test that powder. We have 2 Benchmark powders made by ADI, which are Benchmark & Benchmark2, which is slower. 8208 is slower gain but not as slow as Varget.

Cheers.

Good luck finding IMR8208 XBR….however just as @MagnumManiac said Benchmark is a fantastic powder in a SML especially with 300gr bullets. It’s what I currently use with the 300gr Pittman Aeromax.

Vihtavuori N130 $44 a pound.

Where are you located Darton?

I tried running some GRT simulations and Vihtavuori N120 comes the closest overall.
