Does anyone have any knowledge about the 7-30 Waters Imp? Does it offer enhanced performance over the original 7-30? What makes it improved? I assume it would need custom loaded ammo. I have a 7-30 so am very familiar with that caliber.
billjoe, i'm interested in these cartridges also. it should give more velocity than the original case. it's acomplished by fireforming the case to an improved form. the shoulder will blow out to a sharper angle, and also if there is any taper to the case, it will become more straight walled. but i believe the 7-30 improved just blows the shoulder forward to give more capacity. someone correct me if i'm wrong. you would also need 7-30 improved dies,i guess. i'm not sure how much velocity you gain, but from what i hear 100-200 fps over an unimproved case. the 30-30 ackley improved is very interesting also. :grin:
