Have a buddy who is putting together a rifle in 22-243 AI. Looking for some load data. He reloads all his ammo but is having difficulty finding load data for this round. Any suggestions?

Look at the reloading pages of accuratereloading.com for 22-243 middlestead, there is some light bullet(55 gr and under)data there that will give you a start, If you are looking for some heavy weight/fast twist data do a search on the net. .02
