The 6.5x50mm Arisaka round was designed aound the 139 gr bullet, I believe. That gives me a little room to move. I want to shoot to find out if the old military bore is still accurate enough for hunting. I have my concerns, but have been amazed before. May need a stout load to get the accuracy. We will see. Waiting on dies now.
Did you use the speer Hot-Core hunting or just paper punching? I don't have access to a load testing range - meaning where I can haul wet newspapers out and shoot loads into them. I am curious as to what lower velocity bullet will do.
I looked at the Nosler, but am under the impression that they like the higher velocity for downrange performance and don't want to kick her too much on the practice range. The rifle has been sporterized and cut down before I got it - it's a cute little, LIGHT rifle - the stock is ugly, though I am working on that.
My other option is a varmit bullet at low velocity. Controlled expansion instead of viloent expansion.
We shall see.
