It makes for an interesting day....
I think we are all glad you are OK! Mishaps happen and can focus the mind.
My mishap involved my incorrect sizing of 30-06 brass-I pushed the shoulder too far back, and a VZ-24 with excess headspace. Ruptured case, gas flowing to my face, no injuries ( wearing glasses, with M98 design) but it scared me.
Read an article in Handloader describing mishaps reloading, and what to do, and not do.
Now. I label each bottle of powder with the type, written on painters blue tape on the lid and the bottle. I can verify the type.
I do this when checking my inventory, not reloading. Then I check again. I’m a little OCD.
Only ONE type of powder on my bench at a time .
It takes more time, but I check, verify and recheck that powder before I load the first round.
Then I re- verify the powder when I am complete and store it.
Never blown up a rifle and really don’t want to.
Glad you are OK!
