So I figured I try 45-45-10 vs hi-tek. I lubed up a batch of Lee 358-125-RF. The drop at around 359 ish and 130 grs.. So I lubed, sized to 358 and put a second coat on. Loaded up 25 each of 6grs CFE for 38 Sp at 800 fps (book data) for a cheap range gun I use and 7.5grs CFE for a GP100 at 1300 fps (book data) . I shot 25 hi-tek coated bullets first just to make sure they didn't lead. Then the 25 lubed. In both the range gun and GP they leaded to the point where at 12-15 rounds accuracy was starting to go out the window. So not knowing what the throats are in either gun I was thinking maybe they are getting swagged down (never a issue with hi-tek). So I loaded up 50 for my 9mm pistol leaving them sized at .358 with 4grs CFE with just a light taper crimp they passed the plunk test so off to the range. The accuracy didn't really change after 50 rounds but the barrel leaded (see pics). What am I missing here?
Thanks
