Looks like your getting about 25 fps per inch of extra barrel on me. Your DCM is similar to what I'm shooting. It's interesting how much bad information is out there on this case!

I settled on 20N29. I have noticed I can't get the same performance from a different lot of brass with my 375 DCMs, so it looks like my first lot brass is harder than the current lot. This is the same "harder" brass that I use with 338 DCM.
