Well DrMike if I had an 300 PRC round laying around I could mock up a 300 PRC caliber wildcat based off the 460 Wby case. Just need to blow the neck out to .530”. Finding a .532” barrel blank might be an issue😁
Any of the sizing waxes work or a lanolin/isopropyl mix.
Hornady 1 shot is only good if you like the sound of an 16 penny nail being pulled out of an oak board. That what a case sounds like with 1 shot.
Is it the first round or last round in the magazine or it doesn’t matter? The rear of the follower is snagging on something not allowing it to rise evenly.
This little plot went from this
to this
I took it from my blind. There is a oak to the right and a crab apple to the left in the background. The deer just walk around the outside of it , no one picture of a deer in it. I moved my cellular camera to the oak this past weekend.
I thought the 180gr AB out if my 30-378 was on the soft side. I will add that they were overruns that had a cannelure. Wether this aided it a quicker expansion on the front end of the bullet , I can’t say for sure.
