It’s a just BR with a 40 degree shoulder or what is also known as BRA. The reamer print called it BR Imroved.

What powder and bullet are you using to FF for your 1:14 BRX?

JGS just shipped my reamers. I got a 104 FB and a zero FB with 272 neck.

Make sure you have 4 thou crush.

It’s working pretty good with 29 grains of H-322 under 70 grain Blitzkings and 70 Grain TNTs jammed .015.

If your new brass is really tight to chamber, as in too much crush, I do recommend you push shoulder back just slightly. I prefer .001-.002 actual crush on the brass. Your lugs will thank you and will get more consistency.

19 grains of Bullseye and 1/8 piece of toilet paper.
