I clean my handgun and rifle brass in a Thumbler's Tumbler with stainless steel pins. For handgun brass I prefer to use Remington UMC because the flash holes are large enough that I never find any pins jammed in the flash holes. With Federal, Winchester, and Speer brass I have to drill the flash holes out with a 0.082 inch drill bit. Spend a weekend drilling out flash holes in 1000 cases and you'll learn to just shoot Remington UMC target ammo to get fresh brass. BTW, between Sandy Hook and Covid I made it a habit to pick up 9MM UMC anytime it was on sale for under 10 bucks and small pistol primers anytime they were on sale for under 35 bucks. So I have enough 9mm UMC and primers to load handgun ammo for the rest of my life.
With Shotgun, that isn't the case. I shoot 4 gun Skeet and go thru roughly 12,000 rounds per year in practice and competition. Note, just to give the handgun guys some perspective I just picked up 8 lbs. of H110, which may sound like a lot. Problem is that each round of 410 loaded with H110 requires 16 grains of powder. 7000 grains of powder equal 1 lbs. of powder. So, 16 lbs. of H110 will load just 7000 total 410 shotshells. Basically because I use the 410 for practice I go thru 16 lbs. of H110 in 1 year. BTW, I practice with the 410 for 2 reasons, one is it requires the most precision, the second is 410 only uses 1/2 ounce of shot and lead is expensive.
