Leo, I think the jacketed hollow point bullets are more stable in flight and result in the increased accuracy. I don't really think that 15 grains makes that much difference in recoil to be considered a major factor in recoil. Probably the friction of the copper jacket vs. lead alloy would be more of a factor than the weight, but I don't have empirical data to back up that opinion. I do think that 230 grains vs. 185 grains in a jacketed bullet is noticeable. I've never shot the teflon coated bullets. How do you like them? Do they seem accurate? Do you load them the same as say cast lead bullets? I've shot a few of the old S&W nylon hollow point swc jacketed bullets HP in .38 SPL. They were supposed to allow the firing of a very soft bullet without lead fowling and allow the bullet to expand at lower velocities than JHP bullets, which seemed (back in the day) to required a minimum velocity of 1,000 fps to semi-reliably expand. Bullet designs are so much better nowadays.Mike, do you feel that the 185's have inherent accuracy advantage over the 200 SWC or is it the easier recoil helping the timed event? My current favorite bullet is the teflon coated 200 gr swaged SWC from Precision bullets in Kemp, Texas. Gentle taper crimp is a winner.
