Well, brass grows SLOWER. But it does grow. I trim about every 4th-5th firing, unlike 20°ish shouldered cartridges which are about every 2nd firing.The 280AI is just like all the other AI's basically trim all to desired length after either fireforming or once fired in chamber and done. AI brass doesnt grow that's one of the +'s
I know this is reviving an old thread but a question for all you 280 AI loaders. How often do your trim brass? And how many have you loaded the 190gr/ +190gr bullets? Any loads and velocities?
Do you know what your COAL is? I'm debating whether to keep a FN Belgium Mauser to use as a platform for my build.I had good results with the Berber 195 Elite Hunters out of my 27" barrel.
