Fun with the 6mmGT

[JoeInTucson]

I wrang out the 6mmGT with Staball Match powder and 108 Hornady ELD bullets. Groups ranged from 2520 to 2718 fps. All groups were sub MOA. My favorite would appear to be .33 inches running at 2671fps. Not the fastest but not the slowest either. This is my RPR with a Riton 6-24 mod 2 scope. Only mod was to pull off Rugers brake so I can run my Hybrid 46. All my load development is done with the can attached. Edit…got this in the wrong forum

What barrel length? 2700fps with 108s seems a bit on the slow side by everything I've been seeing.

26 inches. I am not at max.

Gotcha. I'll be putting one together next year sometime. Just been researching and gathering data quite a bit the last month.

I’m all about running stuff on the slow side but you’re below the low node for a 6BR.

Like, almost dangerously low.

Yep.....Ya' need to neck it up a bit. Buddy of mine is working on a 35-GT
length but for an AR.

Try some H-4350 you may be surprised. I am getting nearly 2900 with Berger 109s and a 22 inch barrel.
