just picked up new rifle. This will ultimately be a hunting rifle with occasional range time.
I'm trying to decide what process to use to minimize number of rounds down the pipe if I can help it.
Thus is my first attempt at reloading for a magnum caliber.
Cooper M52 Open County Long Range 300 Win Mag (1-10 twist)
Atlas Brass
Berger 210 VLD Hunders
Federal 215 Mag Match Primers
RE-22 powder
Redding Master Hunter Dies
I was going to load up (3) sets of 10 rounds increasing powder charge by .5 grains only going as high as my Berger reloading manual states and shoot @ 300-500 yards. (Will load 15 rounds @ 2 gr below book max to use as barrel break-in/sighters/fowlers)
But.... should I start @ the lands? .01-.02 jump? I'd rather not jam.
Berger recommends a seating depth test @ .010, .040, .090, .120. But that seams like a lot of extra shooting for a magnum hunting rifle.
This is where I'd like your input please.
