I think because it's basicly a wildcat you won't find much information on it from the common sources. It's popular with NBRSA score shooters and CBA HVY and UNR shooters so there's plenty of good info available. If you're looking for specific info about it for cast bullets look at the match reports or ask here. I'm sure you'll get some decent replies.

Lyman’s 4th CB Handbook has a whole page of 30 BR loads, using a variety of bullets, not just Lyman.

Contained in an excellent chapter titled The Cast Bullet Association & Bench Rest Competition written by Tom Acheson himself.

Thanks, Tom!

The Sierra reloading manual numbers V & VI also contains a short write-up and loading data on the 30 BR, although only for jacketed bullets (for those who like to take the easy way out). Other editions of the Sierra manual may also contain 30 BR data, but these are the two I have that have it.

Thanks guys.I just bought the 51st Lyman book and there was no data. Wrong book, although I did need new a new jacketed book.

I'll get a copy of Tom's handy work.

Going back to 1988, my first "wildcat" round was a 30 BR. This was in an X-100 that was used for handgun silhouette matches. It was built by Dave Logoz in North Dakota. He was the guy at the time who made a lot of XP's for the silhouette crowd in our area, all of which were chambered in 7 BR.....except mine.

When the 7 BR first surfaced, there was no commercial brass so the parent case was the .308 Winch. The case was shortened and reformed. The dies were expensive so a group got together, pooled their money, bought a set of dues and shared the dies.

At that time the 30 BR was also known as the .308 x 1 1/2 Barnes. Frank Barnes was the originator, going back many years. I chose the 30 BR because I wanted to shoot CB's and had several 30 cal. molds. At the 1990 IHMSA Internationals in Ft. Stockton, TX, I used that 30 BR XP-100 to shoot a 78x80 in the Unlimited category....darned turkeys! The bullet was the RCBS 30-165 Sil. and the powder was 4895. I won a RCBS Rock Chucker press as a door prize and I still use that press every day now, only 34 years later.

This was long before IHMSA allowed the use of scopes....my eyes were a lot younger then!

Great topic Ross. A while back I was scrounging around for information on the 30BR and I know of at least one post, can't remember who started it, about someone starting a 30BR project. Was that you?

One question that I never found the answer to was where does 30BR brass come from. Some of the match results show both SR and LR (and SP??) being used.

Lyman’s 4th CB Handbook has a whole page of 30 BR loads, using a variety of bullets, not just Lyman.

Tom thanks for the data and that's a nice article you wrote. You mentioned H322 in the data. When was the last time anyone saw H322 available for sale. I've been watching for a few months and haven't seen any.

Here's last years numbers from the Nationals. Ed hasn't posted the data from 2024 but from the past three years N135 and Varget are pretty common. As is ~200 grain bullets. The Duncan's, who shoot lights out, have been shooting A2495 for the past few years. Thanks, Bill C.

Those groups showing on chart don't look verygood. I think a properly built 308 Winchester will shoot just as well or better.

Hey Bill,

Check the matches. The results are posted for 2024.

Maybe a footnote...

Cases can be made by expanding the case mouth to 30 cal, starting with a 6BR or 7 BR case, both use a small primer. Make sure the reamer being used is compatible with those parent cases.

That Lyman 4 th edition is identified as a first printing in 2010. So some powders might be out of orint 14-years later. The 30 BR loads were taken from CBA match results shot before 2010.

I still think the "industry" should[could] pay a little more attention to the round.

You once could buy factory loaded 7mmBR.

I have 100 new 7mmBR cases and new 30 BR Seaco dies in this round, but never completed project. I was going to make a repeating bolt action Remington 700 in the 30BR caliber. You have to use a modified 223 magazine well to make work.

You have to realize when shooting matches you don't get to cherry pick your condition, bench, or relay and all of those can make a big difference. You're also shooting aggs not single groups. I don't know what the weather and wind was like at that nationals but saying the results weren't that good is assuming a lot.

True, maybe they should list weather conditions at time of groups shot..

I'm not taking a thing away from the 308. Its a great and accurate cartridge and maybe properly set up could be competitive in HVY and UNR class but in my opinion for ease of getting something that'll shoot one of the short 30s is the way to go.

Conditions are contantly changing during a match depending on what relay you shoot and even what bench you're on so picking one set of conditions and saying that's how it was during the whole match would only give you the example for that one small time period.

Pat is so correct! The changing variables DURING a match are frequent, unpredictable and seldom repeatable. To attempt to list the ambient conditions that someone witnessed and then assume it was a constant situation would be foolish at best.

I can recall beiing at one of the CBA National Tournaments in Kabsas City. A highly skilled Plain Base Shooter recalled how he had to aim at the far LH edge of the target paper to get hits to land in the bull. He went on to explain how on a suceeding target he only had to hold 2" to the LH of the bull. So....which wind condition should we say was the "condition"? The former or latter? Remember...the plain base category prohibits the use of gas checks, so muzzle velocities are slower than the other gun categories. Had his bullets been going faster, his correction efforts would have been different.

Just one more tool box skill that some of us have.....and some of us don't.....reading and responding to the wind flags as the wind reveals that it is never your friend.

Yep, I shot the 3 day Nationals the year it was at Raton, NM. Wind was from zero to 20 knots and varied every 10 minutes, not counting the gusts. Being a desert boy, I thought I could read the wind pretty well, but I sure got my come upends.

Conditions are always perfect for that first shot. It’s after that first shot that things go to hell.

By my estimation four 5 shot groups = 20 different conditions.

Hats off to any cast shooter that can agg <1.00” in Production class. How John and others can shoot under that with a skinny forearm factory rifle amazes me.

Short & fat cartridges dominate heavy/unlimited CBA, NBRSA and IBS. Just my opinion. Bill C.
