I bought a 6.5" PC460 a while back, and finally got to shoot it over the weekend. I shot a few rounds of 45LC and then 20 rounds of Hornady 460. It's a beast! When I bought it I was a little worried about loosing velocity with the somewhat shorter barrel. It has a 6.5" barrel and a fixed comp on it (about 1.5"). The surprising (to me) results are below.
My friend had his chronograph set up, so I fired a cylinder full (5) of Hornady 200gr SST's. Hornady's listed velocity through an 8 3/8" barrel is 2200fps.
1st shot = 2274fps
2nd shot = 2254fps
3rd shot = 2257fps
4th shot = 2256fps
5th shot = 2254fps
That's an average of 2259fps, even more than Hornady lists on its website. I can live with that!
Now excuse me while I go ice down my hand.
