Gary...if you recall I have that "pirate" .41 GNR #2 barrel that I got from Kelly B. It is 13" plus and inch of compensator that was a rechamber of a 14" TC .41 barrel. I worked up to 42.0 grains or AA1680 with the 255 CP, 265 CP and 300 grain SSK from Penn Bullets. The 255 ran 2075/2060/2068 over the chronograph. For some reason when I ran the other two bullets I wasn't using the chrono. All I remember is that the 300 grain load hurt to shoot with the Contender frame. I have since bought a G2 frame but haven't loaded for the barrel again...need to do that this spring..Bob

the 41 GNR will beat those velocities by 200 to 250 fps,

What is the max bullet weight for the 410? 255 or 265 grain? (nm)

I wouldn't recommend any bullet heavier than 265
