Bret, my opinion's always been the lubricant needs aren't too great in moderate velocity pistols, and a good lube never lets the bullet get a hold on the barrel as it's floating on an excessive film of lube. Leading's nonexistent, accuracy is likewise.
If I put something like 50-50 or Lyman Super Moly on a single lube groove HG 68 bullet, groups suck. I shoot much smaller groups with my J frame 38 snubbie than my 45 when that happens.
I think there's a reason they put crappy hard waxy lube on commercial hard cast pistol bullets. The crappy lube doesn't overlubricate and groups are then just fine.
