Now, on to some quick groupings. I didn't spend a lot of time (or ammo) doing this as this is far from a bench rest build but I wanted to be able to extrapolate what I could expect down range from each of these loads. I was only shooting at a limited 30 yards with a circle dot Holosun and milspec trigger, so it's still not a great representation of mechanical accuracy... but I shot prone from a rest with the brace supported so it was fairly stable.

3 shot group with Hornady Black - 2.1 MOA. I know I pulled that left shot, so it should have been a little tighter than what you see here... probably closer to 1.5 MOA.

3 shot group with Hornady AG - 2.3 MOA. I've never gotten good groups out of this stuff with almost anything. Usually marginally better than Wolf.
I typically don't do 3 shot groups for accuracy testing... 5 shot groups are where its at. However, given these unprecedented times I chose to save a little ammo and sacrifice my values here. I did do 5 shot groups of the Wolf MC, though as I have much more of the stuff.

5 shot group with Wolf MC - 2.5 MOA. This is typically what I get out of the Wolf MC in most barrels, so that's good. This is primarily (like most of my guns) a steel case blaster so I'm pleased with that.
So, bottom line I think is that this is bottom end on what a few people would consider for 6.5 Grendel for velocity, and below what many would consider at all. This would get you expansion on most modern hunting bullets only to about 200 yards, so you're losing quite a bit of range to even a 12 inch barrel. Moreover, if you're in the suppressor game I think that 7.5 inches would fall below what most cans are rated for. So overall there's not a great use case for going this short. It does handle well, but so does my 12. It does fit in my bag now without being broken down... but honestly you're probably be better off just getting a bigger bag than a small barrel. I didn't chronograph my 10.5 inchers that day, that's probably my next step to give me that in between piece of data between the 12s and the 7.5 inch.
