flat base vs bt
I have a very accurate load worked up for my 308 using Hornady 150 gr BTSP. I ordered 500 more and when I got them and started to load them up I saw where they had shipped me flat base 150's.
If I load these with the same data as the BT's, what changes can I expect in trajectory?
I don't need anger management. I need people to stop pissing me off.
