Well of course I know. 3 650s 2 1050s a 550C and 2 AT 500s and a friend borrowed a 550B set up in 41mag. He likes it enough he wants to buy it. No I don't change primer sizes. The only one I paid full price on was the 550C...and it was on sale for 400 bucks with a free caliber conversion back on Black Friday. One of the 1050s cost 300 bucks and a 650 cost the same at an estate auction. The AT 500s were both bought at gun shows cheap and one 650 I got at a recent gun show with 5 caliber conversions for 400 dollars...so I don't have crazy amounts of money tied up. I buy large estates, sell what I don't need and keep what I can use. I have collected older reloading presses for a few years...but am selling off many of them recently. I use the Dillons, though. Owned 147 metallic presses of older vintage but am down to about 80 now. Hope to reduce that to under 20 by the end of the year due to some health issues(getting old sucks). Anyone can find these presses like this but you may have to buy large lots of other stuff you have to dispose of. I am looking forward to parking a car in my garage soon. Well my wife is anyway
