6.5 CM Virgin brass FPS vs fired and FL bumped ???

[elj1973]

Newer reloader here and I need some advice on using virgin Hornady brass after a load work up with 2X fired Hornady brass that was FL sized, shoulder bumped .002 with a neck tension set at .002 with a mandrel. My goal is to stay in the same velocity and accurcy node. Am I going to have to increase the powder charge? And if so how much with the virgin brass.What kind of velocity drop should I be prepared for? See below for load specs. Thanks in advance.

Not a barnburner load but I stopped cause of the accuracy!! This is the 5 shot 200 yard group with the above load.

All depends on the gun. Chamber dimensions and such. I'd just load the same and compare. No real way to tell otherwise. At least not that I've read or heard about. Should be a little less consistent but close.

It's simple.
Fire form all the cases you need for that barrel, and never change them.

It makes no sense to try & manage different loads for different brass.
