300 Blackout for Score Shooting?
- Thread starter Sling
- Start date
It costs very little to open up a boltface for 30 Major (6.5 Grendel based) or even 30 BR, so why would you want to handicap yourself with a cartridge with only about 2/3 the velocity. To answer your question, it would work, but how well is anybody's guess, probably not competitive.
This is an inexpensive way to introduce new shooters and frugal shooters who want to try there hand in a expensive sport. I have a bolt gun chambered in 7.62x40WT, a cartridge developed Wilson Combat. I'm using once fired Lake City brass to develop a 30 cal BR gun for score at 100 & 200 yards for local club matches. I have found some of my best groups and scores with subsonic loads at 100 yards.

To give it an honest try against the 30br. A zero freebore 300 blk out reamer would be needed and a 17 twist barrel to shoot the custom made 115-118 grain bullets the score guys are using.
It's an interesting project.
Without experimentation there would be no blackout or 30br

Read an article at German Salazars site where a guy was using 300BLK for 300 meter matches and was claiming excellent accuracy. Was it Benchrest accuracy? I don't know, it would seem tough to go up against a 30 BR that's tuned right. But the guys that started the 30 BR weren't sure it was going to be the world beater it is. Only the trying will answer the guestion.

I guess they were hoping allowing the 30br would infuse more interest in that class. Again just guessingboltman13 said:
Joe I've shoot a bunch of 6PPCs that were very accurate. The owners shot with the best at Manatee and could compete. None were even close to as accurate as Jon Newman's Panda 30BR. I've never seen anything like it! I will eventually shoot out my 6PPC barrel and will go to some type of 30 caliber case in my gun. Its a small action Hall and looks like the bolt face is too small to be opened up for a 30BR. Will I be giving up much by going to a 30PPC, or should I cut the base of the 30BR cases to fit the PPC bolt face?
ebb, I would agree that the Hall should be able to be opened to the 308 size, but before you do that, look at Mike Ezell's 30 Major based on 6.5 Grendel brass. Essentially that is the round that set the new NBRSA group record. You'll have to talk to Mike for details, but my understanding is that the performance is comparable to the 30BR. Either way you go, you should have a winner.
