I am interested in the 6/223 as a platform for both XTC and CQB-different rifles to say the least. Can I expect 2800 fps w/ 80-90 grn bullets in a 20" barrel? Will the 6 TCU function throughan AR platform w/o issue like the 6×45/6×223?

I am interested in the 6/223 as a platform for both XTC and CQB-different rifles to say the least.

Can I expect 2800 fps w/ 80-90 grn bullets in a 20″ barrel?

Most reloading manuals will have the case dimensions. The standard 223 Remington case has a 23 deg shoulder and .022 taper from shoulder to base The 6 TCU is an improved version of the 223 Remington case. The shoulder is 40 deg and there is .005 body taper from shoulder to base. The 6 TCU has greater case capacity but not by much. If you have any questions please call 800.717.8211 ask for Ron Thank you Ron Jack,

I'm sure that shooters may be hesitant to share specific load data due to concerns about liabilities, but I'd be interested in any load data any 6x223 shooters would be willing to share. As Lyle said above, I'll honor "All the usual disclaimers" and take responsibility for my actions. You can send a PM to shaw.fe@gmail.com if you'd prefer. I have the Sierra and Hodgdon data.

What velocities are you getting, what overall length are you working with on the 95 gr / 105 gr? Thanks! I’ve been looking at this cartridge for a few years now.

I found that the 95gr. Berger is about as much as the cartridge will handle. Benchmark powder @ 25gr. (usual disclaimers) gives the best score, 190-6x.
