new 300 test loads

Different diameter bullet....7.62x39 bullets are .311. Maybe you could swage them if you had a bunch to use up...

I was able to chrono my 125 gr 300BLK test loads today, Unfortunately, my hottest load of 21.5 gr of LIL GUN powder behind a Speer 125 gr TNT only gave me a best velocity of 2550 fps. I was hoping to get 2600 fps from it. I see no indications of excess pressure, so I'm thinking about trying another 1/2 grain after I have the barrel melonited. I'm starting to get into  compressed load territory here because I can't reduce the seating depth of the bullet any further without having to worry about the rd not being secure in the case. Maybe the melonite process will help the situation a little.

I am curious what OAL you are using? I just loaded 21.5 gr of LIL GUN at 2.165 COAL and trimmed the brass at 1.363. They didn't seat very far into the case mouth but I am about to see if that works perhaps later today.

That was 8 1/2 years ago that @Jgun posted that...   It might be better to try to send him a PM and ask.  If his notifications are turned on, he'll get that notification in his email.

If he responds, tell him to get his ass back in here once in awhile...   

Also, you definitely just won the "Oldest Necro Award."  Well done.

Need to change the title I don’t think they are new anymore. Hey we’re just busting your chops lots of good stuff buried in the vault.
