Casting ones own bullets can be a rewarding hobby and can save you money after the initial expenditure on equip. just like reloading. Just like reloading, you get what you pay for......Lee products can be bought cheap but moulds need to be babied or they fall apart. Lyman, RCBS, Saeco, make good quality equip....you will need a lead pot(preferably Elec. 20# cap.), Bullet sizer/lubricator, bullet mould/s, sizing dies(to fit lube/sizer), ladle, lubricant, lead and tin(for 38/55 you are best to use soft(30-1) bullets), for each diff. cal you will need a new mould and new sizer die....some of this is just my opinion based on many years of casting and being in the casting business, we have an inventory of over 100 moulds, thirty diff. sizers, 3 diff. sizers,etc. We have moulds by LBT,Lyman. Saeco, RCBS, Nei, Hoch, Paul Jones, Hensley & Gibbs, Pioneer, D. Eagan, etc.....When we are not casting bullets, we are testing them.....so we know what works and what doesn't.....my only other advice is to only buy moulds for gas checks if you want the bullets to go higher than 1800fps, as gas checks add to the cost and the labour, also find someone in your area who will let you sit in on a casting/sizing/lubing session before you buy anything!!
