Finally, a 280 AI!

Jake,

Thanks for the update.
60.0-61.0 grs RL 22 should get you to where you want to be. Work with the COL, .010-.020" off the lands, magazine permitting, should put you there.

My 280AI likes 60grs IMR-7828 with a 160gr bullet, real close to 3000fps.Rick.

Jim I'm thinking that is going to be two hot for my gun. Tried 60 gr. again and blew two primers this morning. I did notice that the primers seated a little easier than lest time, but I didn't think they were that bad :shock:. I'm going to try some 7828 this weekend. I might even re work the RL-22. Right now i'm .015" off.

In my new 280AI Lilja barrel one I chronographed both using R-17 and IMR-7828 with 160gr AB using Fed 210M and Fed215M. I didn't have any accuracy problems with either type primers but gained vel with the mag primers.

Might want to switch back to standard LR primers.

Well I think it likes 7828 ssc. I tried the 60 grain load that rick said his gun liked. I think my gun likes it as well. Three shots under .5". I'll chrony them this weekend. I think I'm going to load these three again just to make sure that the primers don't fall out of them as well.

I'll get a pic up sometime this weekend.
