I don’t think I own 40 moulds total. Probably use 6 of the for 90% of my shooting.
I’m a 1 load per gun kinda guy.
I'm pretty sure I don't, but I've got at least a couple dozen old, iron 1Cs I've replaced with aluminum 4C and 6C configurations. All the old ones are still mine, I just keep them stashed and don't plan to use them any more.
What I actually USE is two moulds each for the 222, 30/30 and 44 Special.
The 35 is the hard one, and I have three moulds for that caliber and have been eyeing a fourth. This is for the 357 MAG in revolver and carbine and the 357 MAX in carbine only. The Bradshaw-Martin 194 grain SWC keeps tempting me to expand my mould inventory to TEN.
If I had to pack up and move within a tight window, and was limited on space, I would toss NINE moulds in a box.
Even at TWO per caliber, that's pretty luxurious and I could pare it to one each without hesitation if I needed to.
For the 22s, it's between a 50 and 55 grain and I could close my eyes and pick one.
For the 30/30, it'd be the RDO 311-165 RF
For the 44 Special, easily the 429-421
And for the 35s, I'd keep the NOE 360-180 WFN
I COULD go to just four moulds just like that.
