Do you folks typically use primer and bullet sealant when assembling reloads?
Never have.
Nvere have, never will, have reloaded professionally (as in my father is a Type 06 FFL, ammo manufacturer).
I did once. In 1978. Loaded a bunch of 30.06 ammo for my dad's deer rifle. I loaded almost 200 rounds and he still has well over a 100 rounds of it. Knowing dad, I knew it had to last for a long time (he still has .22 shorts with a Tennesee 1 cent stamp on the box and we lived in Tennessee in 1965.) He doesn't believe in shooting after a shot or two confirms the rifle still "hits where he wants it to hit".
I loaded the rounds first. Then took some model paint (lacquer at the time) and a tooth pick. I dipped the toothpick in the paint and traces a line of paint around the primer and bullet where they met the case and wiped off the excess with a paper towel before sitting them aside to dry.
I can't say it helped, but it made me feel better and those 30+ year old reloads still put venison on the table.
No, never saw the need. Steve :~
I've never seen the need to seal any reloads.
The Box'O' Truth did something on this a few years back. Myth #39 I think.
But anything a civilian is likely to see should'nt require a sealed primer and bullet.
