22 K Hornet
I just got a Ruger 77/22 in 22 Hornet , And am thinking of rechambering it to 22 K Hornet. I have some allready formed brass . Should a person trim befor fireforming the regular brass . Allso when loading the magazine can only get 3 or 4 rounds in it the fireformed brass. They seem to hang up inside the magazine ?
