Hello, everyone..I'v got to vent on this one...I have slowly been accumulating the tools needed to get an original Ballard target rifle in .25-25 Stevens shooting. I have quite a few original Ideal moulds, and have cast up samples from 77gr. to 100gr. (twist is 1-12"). Cases are on order from Rocky Mountain Cartridge. Due to the rifles age & since it's a Ballard, I have decided to play it safe and use black..at most duplex if I want cleaner burn..have purchased Swiss FFFG. I made up 36" 1/4"dia. brass drop tube for charging. I have original Ideal #3 nickled tong tool, but thought something more modern would be in line, so special ordered from Huntington's an RCBS three piece die set in .25-25 Stevens. When I spoke with the salesman on the phone, I asked twice if these were set up for cast-bullet use? He assured me they were, with everything dimensioned correctly..I have had trouble in the past with RCBS & Redding concerning these dimensions.
Well, the dies arrived & first thing I did was to mike the expander...I should have known, .253"dia....Groove dia. is .257, and I had planned on using .258" dia. bullet! For soft cast, I like expander to be at or at most .001 under bullet dia. Case springback takes care of rest, without damage to bullet base edge. That .253 dia. would be a tight squeeze with jacketed.
I will give RCBS a call Monday to see if they have custom sizes available. I checked with Lyman..their .25 "M" die measures .255" dia. better, but still a bit small for soft plain base. Are we cast bullet shooters the red headed step children of the shooting world? I realize it is all supply and demand..but hey, these were "custom" dies..at the very least, they could have gotten closer on the expander size. Thanks guy's.
