I think it does. I also think that the gas getting ahead of the bullet affects the potential accuracy.

I actually see this type of fit with the Taurus semi-auto pistols. They all have large groove diameters. The firearm will never match velocity expectation nor live up to it's accuracy potential. Stick a fat bullet in it to seal the barrrel and you will see higher velocities and tighter groups.

Check this out. When I ordered the Woodleigh bullets, I bought a 303 British Lee Loader and another Lee Turret from MidwayUSA. That outfit has gotten real bad about throwing everything in a bag so UPS can sling it around. Here is how it arrived.

I haven't had the time to get and email to Mr. Potter but I will. I'm tired of my orders arriving like this.
