I have a Sako Alaskan Hunter. It was a special run some 25 years ago that has a 20″ barrel. In the process of trying to find a powder for the 200 grain Speer bullet with less muzzle blast I tried 4320. Accuracy is amazing. I don’t have a chronograph but testing showed it has about the same trajectory as a 180g bullet from a 30-06. Yes there is still some muzzle blast but no where near as much as factory.

I’m using this powder for 223, 308 and 458 Lott. I wish it was suitable for 375 Ruger as well and I would use it in that. It’s been very available anywhere I go.

I have a custom built 358 Norma Mag that loves this powder, 3/4″ 5 shot groups all day long.

4320 has worked well in all the rifles I’ve tested it with. 45-70govt, 375H&H, 300 win-mag, and 270 bullets ranging from 140-400 gr. I can pin down a 300 yard soda can with my 45-70 shooting a 400gr barnes bullet with a good dose of propellant. doesn’t seem too picky bout the charge either, just has to be close to max to shoot real tight.
