Too bad you can't get H0205 any longer!!
I just moved back to my old house in upstate NY from having lived is PA since 2000. Imagine my surprise when I discovered half a pound of H205 here. I used to use55.7 grains of thispowder with a 200-grain Nosler partition in my J. P. Sauer 8X60RS double rifle for a MV of 2620 FPS. This load shoots into 2.6" at 100 meters fromboth barrels.
While in PA, I worked up an accurate, regulating load with the same bullet, using 59 grains of RL22. But the MV was only 2450. I hope this H205 powder is still good! It looks OK, but powders do lose strength from absorbing moisture over the years. And this is a real HUMID place!
I'll try it, however!
Here's a target with the 59 grain, RL 22 load fired at 100 meters, using both barrels.
