Tennessee, what’s the story? Is there a 223 or not? Mag length for the twist or not?
Berger 80g VLD average COAL to kiss in two rifles is 2.408”
Mag box is 2.436”
So with that bullet you can load to kiss with room to spare in the mag and even some to spare for future throat erosion.
I personally would not load to make contact with the bullet. When the chamber is precise and the throat is tight, I get great results with a little jump. Assuming the load has the best powder, density, primer to make consistent pressure and low velocity SD....
