As I've proven here to the satisfaction of the most erudite observer, the following don't matter in the cast bullet world:
Powder charge weights that have any digit to the right of the decimal point other than a 5 or zero
Lubricant choice
Alloy composition, within broad ranges
Primer choice, within reasonable ranges
Bullet sized diameter, S.T. the throat-fit requirement
Bullet design, bore ride, Loverin, Pope, Lyman old stand bys
Brass make or weight or primer pocket uniformed or flash hole deburred or neck turned precisely
in the world of five shot five group 100 yard averages between 2” and 1.5".
Since my world-rocking experience with IMR4198, I'm wondering just what the accuracy search protocol should be for a gun that is going to remain stock. This means before re-throating, bedding, bore-lapping, muzzle crowning or sending the stock out for the cryo treatment.
For, for instance, a military rifle or M700 Rem/M77 Ruger/Savage 1X/ other non-target rifle, new or used. Or a Competitor pistol.
You ended up with this rifle, you want to get it shooting cast bullets, you're a reasonably experienced reloader/caster, what do you do and in what order?
(Pat; don't help them. Can you see the article?)
Huh?
