Hi, I'm very interested in learning how to reload, and until recently when shooting my Judge had no idea that you could reload 410's (I'm new to guns)until a gentleman at a range asked for my shells. I didn't see 410's in the Speer book, and since i have the option, figured I'd ask you guys which is easier to learn. I know that shot gun shells are cheaper, and doesn't seem worth the effort, but if i could recreate the PDX1's that would be awesome! I'd like to be able to cast bullets/pellets as well (seems like 410 would be more fun in creativity of different loads . ) So for a novice with an option.... learn 410 or 45? Thanks!!
