7mm BR

Does anyone have any experience with this cartridge? I was thinking of getting one and wanted some opinions on performance.
 
I don't have any with the 7 but I have a 6 BR and it is one very efficient cartridge! I think all BR's are inherently accurate.

What are you planning in doing with it? From a target/benchrest perspective, the lack of really great bullets is the biggest downfall.
 
I shoot a 7MM BR out of a pistol. Very accurate on paper way out. On animals about 200 yds. It just runs out of steam to open a bullet up.

7MM bullets have great BCs. For deer shooting 125s for paper usally 100s.

No great 7mm bullets? Do tell.

I'm thinking many of the long range guys and gals would argue that point. They have been at the top of the food chain for something like 20 years now. Granted it when you go to ELR distances of more than a mile folks tend to use 338s, but the 7mm are what they are due to great bullets and lots of choices.
 
One of the best reasons to shoot a 7mm cartridge is the huge selection of truly outstanding projectiles, in weights from 100 to 180+ grains. The line-up below shows but a small fraction of the excellent 7mm projectiles available today. As the 7mm has been a favored hunting, military, and target caliber for well over a century, bullet-makers have had plenty of time to perfect their art. For game hunters, the choice of great bullet designs in 7mm (.284 caliber) is rivaled only by the wealth of 30-caliber bullets, and the 7mms enjoy a ballistic advantage, grain for grain, over the larger-diameter 30s. All the major bullet makers offer outstanding hunting bullets in the 130-160 grain weight range: Barnes 140gr TSX (.412 BC, tipped, lead-free) and 160gr MRX (.439 BC, tipped), Hornady 139gr SST (.486 BC tipped) and 154gr Interbond (.525 BC, tipped), Nosler 140/150/160gr Partitions (.434-.475 BC), Sierra 150gr GameKing (.436 BC, SP), Speer 140gr Trophy Bonded (.360 BC, SP) ... to name just a few. Whether you want an explosive ballistic-tipped bullet, high sectional density for penetration, or a bonded core for high weight-retention, you will find a 7mm bullet design that does the job exceptionally well.

Hmmm?

Go look at ANY benchrest match results, and you will find limited use of the 7MM, because of bullets. Please note I said from a benchrest perspective. For hunting or shooting from a standing position, it's not an issue.

In the 600 yard and 1000 yard benchrest matches, there are 2 dominant calibers, 6MM and 30 cal, with the 6.5 real close. Granted, the 7MM has great BC, but people that shoot these matches are looking for the best of the best in bullets. GTB, Berger and JLK are about the only choices out there, and they are dependent on the quality of the jackets available.

Not long ago, the 6.5 was not even considered for long range benchrest, but when the 284 was necked down to 6.5, bullet makers came to the rescue.

From what I've seen, the 7BR has been mostly a silhouette cartridge, and for that I'm sure it does fine.But ust look at the other two BRs, the 6BR and 30BR. What makes them shine? Bullets.
 
There is definetly not as many match bullets as hunting but the match bullets that are out there are great bullets. I do not shoot competions but in my head a Berger VLD 180gr with a BC of .684 would be a great match bullet. That said, coming out of a BR case it's gonna be losing steam quick.
Thanks
