Leading Theory of Bullet Weight vs PF
So lets say both loads are 130 PF and are using the same sizing die and lube.
Current load is a 156 gr bullet (147gr Lyman mold with range scrap lead) going 830fps. I get a small amount of leading in the throat which actually improved a bit with the softer range scrap lead. Either way it's not bad so I am not worried about it at all.
So I am thinking of buying a new Lyman 120 gr mold which should pour at 127gr give or take a little of course. That bullet would be going 1040fps using the proper amount of powder.
Here is the only question. I know this is just a guess. Will leading get worse? Pressure should be a little higher but not a lot higher if at all.
Yes, I post using a phone so my spelling sucks.
