The Lyman 450 lube sizer I bought in the early 1970's was the best money I ever spent.
Pan lube was messy, I spilled lube on me ,the floor ,the table, my pants and the dog .
Tumble lube with alox was OK but I don't like the alox all over the boolit and you have to lube them then size them then lube again .....it's a pain .
The lube sizer....one cycle of the handle , the boolit gets sized, lubed with a good lube and a gas check gets seated and crimped. Done , neat & clean , no muss , no fuss!
Buy one ...you will like it. Alox runs out when the velocity gets up.
At the time I bought the 450 I thought it was a lot of money, after doing a few boxes of boolits I was happy to have spent it and I'm still using that same unit today . It has paid for itself a zillion times.
