Hey everyone! Just loading some 45 for some friends and myself when it downed on me that with a shell holder change and the dies I could be doing 10mm in a hurry!!!!   The main thing is not having to change primers from small to large etc.   Craig

Yep, swap the dies and shell holder and get you some of that 10mm going!   

I do all my Large primer reloads together and in large batches. I'll usually do  1000 of 45 auto and 10 mm and then 500 of 44 magnum. If I need 7.62x51  i'll do those as well. I have a Dillon 550b  and for me the hardest thing is to change out the priming system.

Once I finish those then I'll switch out the priming system, I've got to keep the 5.56 running as well as the .380, 9mm, .38spl and .357 magnum.

So yes I agree the main thing is not having to change out primers from small to large.
