35 Whelen IMP SOLD
7x57 IMP. $75 shipped
What does IMP mean?
Ackley improved, or improved 40 degree. It will not work for factory chamberings of 7x57 or 35 Whelen. Only if your chamber has been Improved. If you haven't heard of this it has been around for a long time. The books written by P.O. Ackley are really cool.
Hope this helps. Feel free to ask any other questions.
