Well, I know nothing about that firearm in the picture, but our sniper team ran Tikka T3X Tact A1 rifles chambered in .308.. they only had 16 in barrels and per our chronograph were moving 168 gr AMAX bullets at 2450 fps out the muzzle. But they were exceptionally accurate and we shot out to 1,000 meters at the US Military Yakima Firing Range Training Center and at the range at JBLM... I wouldn't think that a ten inch barrel wouldn't be ideal at beyond 500 meters but then a lot of people thought we were dipshits for using 16 inch barrels at 1,000! And a lot of those people using way more expensive guns weren't shooting very well.
I saw this too! A pretty wild and unique setup. With a Ti can it would be pretty awesome. They're still available, as of me writing this.
If anything it will be a lot of fun to try. This is a cool gun.
