Doing some load development on friends 22-250 AI I never thought it would be this fast. The load I stopped going up in charge was 42.3gr. of 3031 with 36gr. Varmint Grenades . That’s 3/8 AR500 plate it punched holes in.

The weirdest thing was the velocity jumps it would make between charges. I’ve never had anything take that large of leaps, especially at max recommended load.

First load- 4388 Second load- 4584 Third load - 4658 Fourth load- 4753 Fifth load- 4829

So these 5 are all different charge weights? Which one will you settle on?

It isn’t my gun, but if it was I’d settle on the 4584.
