I did get to test them over a chronograph with AR Comp... they were running close to 3900 fps out of a 28 inch barrel..
sadly it won't stabilize in the one in 14 twist...

the Ruger has a one in 12 twist... and then I have a Pac Nor Barrel on a Ruger Sporter with a real fast twist.. that should shoot them real well... or at least stabilize them..that rifle has a 24 inch heavy magnum contour barrel on it..
