I recently bought a 1K heavy gun chambered for a 300 Weatherby Magnum case with a 40 degree shoulder and the belt removed. The brass is fireformed by seating a bullet with enough neck tension so that the round will headspace on the bullet with a new case and then on the shoulder after the case is fireformed.
The gun shot very well in my first match with it on Saturday. 210 Bergers went out about 3,000 and really cut through the wind. I want to order a reamer in a 300 Ackley caliber to use for both LG and HG in the future when I have to rebarrel and as this is my first experience with a 300 Ackley I have a couple of questions for which I can't seem to find answers easily...
Do other 300 Ackley type cases,with belts) headspace on the belt or on the shoulder? If on the shoulder how is this done when the belt remains on the case?
As having the brass prepped,turning off the belts, etc.) for the chamber I now have will get pretty expensive I'm wondering if there is any particular advantage in doing this?
Thanks for your comments.
