I am considering an SBR 10/22. Anyone know at what point a 22lr stops gaining energy from a longer barrel? What will cutting it down to 12 or 14 cost me in FPS?
The ten inch barrel on the Charger seems to be about the idea length for the pistol. The muzzle has a recessed crown, and the barrel is of a medium-heavy profile, measuring .920 inch at the receiver and tapering to .664 inch at the muzzle. Testing for velocity loss from the shorter barrel compared to a longer one, I fired over my PACT chronograph the same ammunition from both the Charger and a 10/22 with a sixteen inch Tactical Solutions lightweight bull barrel. As an example, high velocity Federal hollowpoint ammo averaged 1203 feet-per-second (fps) from the sixteen inch barrel, but still averaged 1163.9 fps from the ten inch Charger barrel. Not bad at all. Target grade standard velocity ammo lost even less velocity. The trigger pull on the test pistol measured just under four pounds. The .22 Charger weighs in at 3 lbs., 9.6 ounces empty. Adding the bipod and a Leupold scope brought the total weight up to 5 lbs., 1.3 ounces ready to go.

well.... obviously you dont, but i do
Well, I like google too, but I just don't rely on the info I find using it for making large purchases. Especially when I realy don't know enough to say if the answer is reasonable enough or not.
