6BRX is a cartridge based on the 6BR that shoulders have been blown .100 forward with no shoulder angle change and no other changes. Hence the 6BRX die.

A 6 BR 30º sidewall blown forward .017 and formed to a 40º is a 6 BRA. A 6 BR 30º blown forward .050 to form a 40º shoulder is a 6 BRDX. A 6 BR 30º blown .100 forward to form a 30º shoulder is a 6 BRX. A 6 BR 30º blown forward .100 and formed to a 40º shoulder is a 6 Dasher. A 6 BR 30º blown forward .125 and formed to a 40º shoulder is called a 6 BS ( Bill Shehane) Dasher.

6 BRX
The 6 BRX is the brainchild of champion F-class shooter Bob Crone. It leaves the shoulder angle unchanged so you can use regular 6mm BR dies, though a custom reamer is required to cut the chamber. While 6 Dashers seem more common, the 6 BRX offers equivalent performance with lower tooling cost. For that reason, the 6 BRX may be the smart “improved” choice if you want more velocity from your 6BR. Clymer Tools has the reamer for the 6 BRX, using Crone’s original design. Pacific Tool & Gauge also has BRX-style reamers. Specs: 30° standard shoulder, blown forward .10″, neck-length = .210″. Can use standard dies, but the case will not fit a standard chamber. While the BRX gives up a little capacity by using the standard shoulder angle of the 6mm BR Norma case, velocities will be right up there with the 6 Dasher.

Actually, I just measured all my go gauges for the 6BRX, The 6 BRX Whitley is .100 longer than 6 BR. The 6 BRX Crone is 1.280 longer than a 6 BR or .0270 longer than the Whitley 6BRX.
After close to 20 years of hydro forming BRX brass for customers and myself, I have found that there are more Whitley chambers out there now. Very few ask for a Crone chambered formed BRX brass due to the very short neck.

No, the Crone BRX die will not touch the Whitley shoulder. A 6 BR die will bump the shoulder but will not size a Whitley or Crone at the .200 line.

The GT is very unique as it has a 35º shoulder and requires a die for that specific brass.To me, the 'BRX' (in any caliber) offers the most blend of features of a bigger BR case. The 'best' big BR case is probably the the GT.
Good shootin'-Al

I have shoot the BRX since the0 article in the Daily Bulletin hit in this forum many years ago. Probably 25 barrels at times 2 guns in a season. I have won from 100 to a 10000 yards, group, score, paper, steel. All with Varget, 107 SMK, at 2990. So thinking a change would be fun I shot a 6BRA last year. If I do any more barrels, nearing the end, I will probably go back to the BRX. Great cartridge.

Never tried any of the other off-springs of the 6BR but the 6BRX is definitely one of my favorite cartridges to load for and shoot. Very easy to tune and keep in tune which is considered to be the most important by many.
I shoot 6BrX more I shoot anything. When I built my 1st several years ago. I sized and bumped shoulder with an adjusted 6br. Die and size the bottom with small base 308 die and milled a base to seat with an inline 6br. Die now I have and use all 6 BrX dies
Really to be honest I don’t know which Version of the 6 BrX I have but the dies I have does the job

The whole 6BR family is amazing.
Really happy with my 6BRA for the reasons you mentioned.
I actually set my chamber.008 just have a smidge more case capacity because I was planning on using a slower powder than most.

And,.. hvy gun ??

Jeff, which BRX cartridge would you choose if you went back to it? Whitley or Crone.
Thanks
