One thing I do though, is never chamber the same round repeatedly. Multiple chambering will set a bullet back in the case and create a dangerous situation.
Offhanded checking by me reveals that in my Kahr, each chambering shoves the bullet in about 0.002". More or less. Kinda sorta. YMMV
And remember that a heavy-recoiling revolver can pull the bullets
out a bit with each shot. Never checked that myself, though.
The only reason I weigh complete bullets is if I forget what bullet weight I have in the gun.
Actual example, I had a half tray of nines (no outer box) stashed in with a 9 handgun in a case and couldn't remember what bullet weight they were.
Weighed three of the unknowns, was 34.9 grams total. Weighed three known 115 gr cartridges, was 35.7 grams. Weighed three known 124 grain cartridges, was 37.1 grams.
Converting to grains, the unknowns were each about 7 grains lighter than the 124 grain cartridges. Therefore, even considering variation in case weight and powder charge, they must have been 115 grain bullets in the pistol case. For more precision, I would have compared more.
Yeah, I know, the mistake was in not using the outer box for IDing them in the pistol case, but these things happen. It had been two or three years since I was testing that gun for reliability between 115 and 124 grain bullets. Darned thing was unreliable with either cartridge anyhow, which is why it was put away for that long.
