Thread: Fire forming AI brass

Robs 22-250AI's we just do a load for fire forming, Usualy easy to get due the less harmonics with the brass taking some of the sudden preasure while it streaches, Both times it was 4x4 rounds and found a load, so 16 rounds load development and 84 rabbit and Pooks (distruction order when they are seeding) ...Not one miss...well so he says

Then in that it has been 1gr more for the best group and only 16 rounds loaded to test the load in the formed brass and its all go...might try another powder one day to get some more speed but he is happy as with the way it shoots.... James your old stock is on that rifle

My 243AI was deadly accurate form firing as well but using the 87gr Vmax and 90gr BT......Goats didn't like it anyway and the kids loved shooting the steel hanging paddles as well.... Just had to watch Rose or she would empty the box if given the chance

lethel, what powder were you using in the 243AI? Was thinking either 2213SC or 2209 (or Win760).
