Use the max load data for 22-250 and start there. You will probably be between 1-2 grains higher after your brass is formed and you start adding powder.

That’s very kind! I’m happy to pay the shipping

Hmmm fun caliber... 5,000 FPS That is RIPPING NUTSSSSSS!!!!!!
I’m running the 40 grain Berger FB varmint 4,500 fps. Sub 1/2 moa to 500 yards. Lots of groundhog orphans in my neck of the woods. Next barrel will 1:8 to run the 88.5 grain Berger. LR hybrid.

BTW, I’ve used the recommended fire forming load with great success.

I have just re-barreled my 22-250 to a 22-250 AI
This barrel has a 1 in 8 twist.
Can anyone help with reloading ??
Want to shot 60 gr bullets and heavier
I do have loads, that I developed in a 27" inch barreled .22-250 AI with a 1-7 twist barrel using Berger and Sierra 80gr match bullets. All my loads were very safe in my rifle and they showed no signs of pressure if you're interested I'll forward a few of the most accurate loads to you.

You might be surprised by how much barrel life you can get from a 22-243 (or the AI variant) if you treat them right. :D
It was just a pun, over bored cartridges are known to be throat burners. But 5000 FPS is insane. When the 220 Swift came out bullets were not up to snuff and some came to pieces before impact with the target.
