I would go with the heaviest bullet with a cannelure.
This is what I had understood and yet a number of manufacturers will offer 300gr options without one...
Annoying really as it limits my choices further.
Well, that means I should discard the plated option: I was chided for putting too heavy a crimp on them leaving a groove in the body of the bullet...
The light crimp I'm using with the 200gr bullets and starting loads is still allowing some bullet creep, so I can only imagine what would happen with a hot 300gr bullet!!
That leaves either the SJFP 240gr or the 300gr hardcast Midway offering!!
You cannot wake someone who is pretending to sleep. Stop pretending. Wake up.
Doubt: ...it's the only thing I'm sure of...
