I was pretty meticulous between shots, albeit not as much as you, I bet. I even gave the barrel time to cool down between the Mags and the SWs. I hadn't thought about the striker slowing down, but I really don't see a lot of fouling back there, so I wonder how much slowing there really is.

I'm actually out of Mags at the moment, so I was planning on starting out with the SWs next time to see what happens. I was planning on using the 300 gr SWs for hunting. If they consistently show a 6" arc (compared to the 245gr MEs), I might rethink that.

55 addional grains of stopping power, or flatter trajectory? Problems I enjoy solving.

Cheers
