Talk to me about 30 BR

Just like the PPC dominates in short range group competition, the .30BR does in IBS and NBRSA score. For that reason there is a lot information available. I would suggest that you do searches on forums. There have been a lot of threads. While match bullets are more expensive than 6mm, the extra barrel life (5,000+ rounds) more than makes up for it.

The 30BR is no push over. It is accurate and fun to shoot. For the .330 after necking up turn your brass to .098 and go shoot. Several custom bullet makers product accurate bullets from 112 gr. to 125 gr. Best powders are H-4198 VV-N130 & LT- 30. Speeds around 2950 to 3000 fps are common areas of accuracy.

Thank you for your reply. I always am sure to read your posts here on any topic.
I have found a wealth of technical information and history on the 30 BR. The article @Jager (Thank you) posted is great! The technical aspects of reloading and shooting are a major part of my ongoing interest in shooting.
That being said, I was hoping to elicit some subjective responses. In addition to being an advantage in Scoring shooting and easy to tune, what is it people 'like' about the 30 BR.
Thanks!

Well, I think it's a truly great cartridge.
It's design and proportions - think expansion ratio, and resulting muzzle pressure at typical barrel lengths - make for an inherently accurate round. It tunes with far less effort than many cartridges. It is very forgiving in that regard.
And as a bonus, its cartridge size / bore ratio make for very long-lasting barrels.
It's only real downside, for some, would be the extra recoil it brings to the party, relative to its smaller-caliber cousins.
The .30 BR is a beautiful piece of work!

Keep in mind that to capitalize on any theoretical "...advantage" the .30 has in Score shooting is dependent on a couple of things.
(1) First of all, it needs to be as accurate as any other well tuned cartridge on the firing line.
(2) The recoil is significant when compared to smaller chamberings
(3) Your table manners (gun handling) is critical with the .30's as compared to smaller cartridges.
(4) The guns balance is critical.
(5) The cumulative effect of all this add up when you're shooting two yardages a day.
On the upside, it's a wonderfully tuneable cartridge that has a wide tune window. If you follow the road map for a reamer, making brass, seating depth, neck tension and bullet selection....it just doesn't get any better for a SR Score cartridge than a 30BR or one of it's close cousin derivatives.
They're so simple and there's so much history and published facts about building/tuning a 30BR that people shouldn't be able to screw one up......

Ya know how it works. You give a little to get a little. But, your correct. My best 30 barrel is at about 7500 rounds. I wish I could shoot to its potential. I shot it several weeks ago at a match for the first time in several months. Took the first 2 targets to get comfortable with the recoil.

@DaWhit Is the 30 BR easier to tune than the 6 BR? Does it stay in tune over a larger range of atmospheric conditions?
Bullets are not exactly redily available. I looked a few places and don't see any Berger 115s. Sierra doesn't make anything that light. Is boutique makers the only place to get bullets?
How do the 30 BR and 6 BR compare as to tunability?

If you want it to shoot to it’s potential seek out custom bullets.
Regarding the 30BR, the sole negative attribute is recoil . . . and THAT can be quite subjective. For a bloke such as I, used to shooting 10.0 Lb., 30x47HBR chambered Hunter Class Rifles, even a LV/Sporter weight rifle free-recoil (10.5#), "is like a paid vacation". 
Jager's post - #6 above - pretty much encapsulates it. The, "table manners", pointed out by Al Nyhus, become either an acquired skill, or, a detriment.

Sierra and Nosler both make a 110 gr. 30 cal. varmint bullet that works well for varmint hunting, plinking and the likes but neither will shoot accurate enough to win matches in my opinion.

Thank you @Bill Norris
Sierra have there search segrated by types. I was looking in MK and TMK.
Bergers don't seem to be available anywhere.
No rush, I'm going to play with the 6mm barrel first.

Ain’t that the truth. Depending on what day it is.
Currently having a 30br built. I know this probably isn’t a concern, but you did mention it.
Hottenstein had/has 112gr 30cal bullets.
I got an email from barts that they got jackets. Don’t know if all are spoken for yet.
Ammerman Arms has 118s in stock as well.
Euro optic had Berger’s in stock a few weeks back, and they can be back ordered I believe.
Just letting you know to try and help make your process a little easier, cause it was a pain for me to find them.

As I have commented on other threads, I think you have to work at it to not get a 30 BR to shoot.
Easiest cartridge to tune ever, fill the case with H4198/LT30 jam seat a 112 to 118 bullet of your choice, (I like the Bergers) and go shoot dots.
If you are really OCD you can fine tune the seating depth but jam usually works in most barrels.
I just don’t think they will quite Agg with a PPC, but that may be do to the “gun handling” aspect of the increased recoil.
My experience worth what I charge, YMMV

To be a bit more accurate:
I use 34.4 gr H4198, @ a grain more if I’m using LT30.
