That 78 fps loss was with a bullet up around 1200fps, the 147 grain difference of 53 fps would be more along the velocity of what I would use in it (HST 147 grain) and so would probably lose around that much? Again though, that much would negate about HALF the velocity increase between a 2" and a 3" barrel, so I don't see the point?
I have a ported 608 that has a 4" barrel. That's not bad because it's 4" to begin with. I can't see porting a 3" barrel, and losing fps, if one of the reasons the buyer wants a 3" barrel is because it's faster than a 2" and the HP's are more likely to expand because of it?
