As titled I’m looking to id an alternative to Varget for my 223. Hands down it’s the best powder I’ve used for my rifle but availability and price seem to be an issue. So, I’m looking to test out some back up powders. Looking to get over my target through some logical suggestions. Before suggesting anything consider this:
R700 HB, 20”, 1/9” twist. I have tested H335, H322, Benchmark, H4895 and Varget. The rifle does 3/4” with 40gr and 53gr VMAX, and 69gr SMK’s, all with Varget. All other powders, the groups open up to 1-1.5”+. Velocities with the lighter bullets and other powders go way up, but accuracy diminishes. With the 40gr VMAX, H4895 and Varget give me the exact same velocities per grains of powder, but groups with H4895 are larger across the board. Primers haven’t made a difference, but powder has. The bullets I’ve had the best luck with all don’t like to be jolted out of my barrel. They seem to like the easy ride that Varget is providing. I’m assuming it has to do with the faster barrel twist.
What other powder would be a second best that might be worth trying? From looking at burn rates, seems Varget is the slowest I’ve shot. Faster hasn’t worked well. Perhaps there is something close or slower that someone has had success with?
