View Full Version : Reloading 62 grain Barnes TSX

July 9, 2012, 04:23 PM
I have been trying several powders with the 5.56mm Nato chamber using Barnes recommendations for the higher chamber pressure 5.56mm. Rather than using LC 09 brass like they did in their online data, I substituted Federal cases and got blown primers even at fairly low velocity (2700 fps) with RL15 and BLC-2. Varget was OK up to 2750 fps where I stopped. This from a 16 inch 1-9.

Do military cases have that much stronger of a case head than commercial brass?

I thought the larger case capacity would make up for loss of web thickness?

Any advice?

Perhaps this would be a better fit in the Reloading section.
