Hey Brother, Without sounding like the know it all post police, I think what you meant to post was significant loss in velocity(in the author's opinion). There was something akin to twenty or so FPS per inch chopped. It wasn't until they got down past twenty inches that the velocity loss started to increase substantially... That said, my custom quarter MOA bolt gun sports a 26" tube. Velocity is a funny thing. Atmospheric conditions play hell with it. So, I like to err on the side of extra margin of error. So if I'm shooting in some low cold location, she will still get the job done. I also live in Jersey, where suppressors are verboten. Having a 26" tube guarantees me a complete powder burn for reduced a muzzle flash and report(target indicators), since it all happens in the barrel instead of the air in front of my muzzle. Now, to be honest, shorter barrels can still reach longer distances, provided there is ample range of travel in the scope. There will be greater adjustments needed for range and wind will also have a greater impact, but it can be done. Rounds will also matter a bit more, as you'll need a round that remains stable as it transitions to subsonic, at range. Some get very erratic during the transition...I have every intention of shooting my POF 16.5" Recon at extended range. Will it do what my bolt gun does? Nah, but it should still get the job done if the loose nut behind the trigger hangs on... I hope this helps... Respectfully, Harry
