Hi,
I've got four Versamecs (fancy version of the 600 when they were in production) dating back to about 1975. 12, 20, 28 and .410 for all gauge skeet use. Also have a "newer" 600 Jr., probably 20 yrs old by now. All have served well, with probably 150k+ rounds on the 12 ga Versamec after I put away the skeet gun in favor of a trap gun. About 50k between the others combined. Can't find it in the rubble right now, but I believe my original Mec 250 (20 ga) from Christmas, 1965 still lives here, too.
These single stage MECs aren't fancy, but will load tournament winning ammo, and given reasonable care, will last most users a lifetime. And if something does give up on them, MEC's really good about furnishing spare parts. Several online vendors also stock the "usual stuff" like charge bars and bushings, wad guides and a couple of other items.
Haven't "done the math" for a while, but when I was loading shotshells regularly, I figured I could load a "comparable" shell for about half what the factory charged. So if a box of Win A-A trap loads ran $7, my trap loads were about $3.50-$4.00. A $20.00 box of factory duck loads ran about $10.00-$12.00 to duplicate. There's no way I could compete with Wally's bulk packs for price, but there's no way they performed anything like my better grade loads, either! To top that off, it's a long story I won't tell here, but a major brand promo load was responsible for blowing the end of a barrel on one of my 870s once--that was really a false economy, and I never bought another one.
