AI: Ackley Improved. It's a blown out case with minimum taper and sharp shoulder angles.
You could probably add a grain (possibly two) to the overall starting and max loads for the 22-250 and be in good shape. For safety you could start with the basic 22-250 loading info and move up from there at your own pace/pleasure/tolerance for adventure.
Good Luck

I finally clicked past the disclaimer page and found that site very informative. I clicked on a few calibers and the loads seemed to run the range that I've seen (starter to max). For example, the 308 Norma max load for H-4831 appears to be close to the Lyman loading books max load which I consider smoking hot.
I was curious where most of the loading info came from? Sorry if it's explained within the website but I take brief trips out to the internet while at work and couldn't spend too much time.
Thanks in advance.

The data is developed by me, at the range.

Dick, That was one of my favorite coyote calling fur cartridges ever. I used a Ruger 77 action, MPI stock, Douglas spoorter barrel, and Tasco World Class Plus 3.5-10X that had been customized by T.K. Lee with 3 dots along the vertical x-hair that corresponded to the trajectory of one of my favorite fur loads of all time-- The 40 gr. Nosler BT. @ 4350fps behind ?gr. 4064. I turned the lights out on several hundred coyotes with that rig/load for several years before the throat gave out.

I shoot a 22-250AI. I only use two bullest, the 60vmax loaded with 40 grains of H380 and the 75 grain amax loaded with 42 grains of RL 19. Both loads are max so approach with caution.
I have a 26 inch barrel with a 1-9 twist.
Hope this helps.

I had a 40X single shot 22/250 AI. Best shooting gun I ever had. If you want top velocity and in my case accuracy, try H414 powder. H414 and Nosler 55 grain bullets were the 1/4" favorites. I'll look up some old data for you and post it when I get home. I was able to actually shoot some old Hornady 45 grainers so fast that the bullets desintegrated in the air. It was fun to play with and absolute poison for groundhogs and crows. A really nice caliber.
