1. DO NOT buy a Harbor Freight unless you purchase the extended warranty. They have a counter weight on the motor shaft to make it shake. The motor bearings will wear out quickly and the motor will freeze.
Lyman and Vibra shine are good ones without the HF problem. I use ground corncob that cost $3 a bag of 5 pounds at gun shows.
The trick is adding drops of Brasso to the media.
Dies and Die parts? Lee carbide pistol dies with shell holders are great and are cheaper than RCBS. RCBS are Caddilac of dies, I buy used dies when the price is right at gun shows, flea markets and garage sales at prices like $5-15 even if I don't have a gun in that caliber.
Press- started with an RCBS junior kit for $59.00 from Midway in 1979. You do not need a Rock Chucker. But I hit an auction last summer and the Rock chucker was not advertised. I got everything you need to reload including 3 sets of dies, bullets brass, primers, reloading books. some powder, and powder dispensor, scale primer feed, lube pad, lube.. Paid $20 for one box, $100 for the box that had the press.
$120 for about $650 of equipment. This auction had about 40 motorcycles, a corvette, 56 Ford and thousands of tools. Got lucky no one else wanted the Rockchucker.
Do check EBAY for prices on reloading stuff.
