Well, let me see,,,,,, NOS Winchester head stamp brass is going for $1.50-$2.00 per case (that's $150.00 to $200.00 per 100). It can be made from 30-30 Win. brass which is "no easy task" according to Nosler. 25-35 would be a better option IF new brass could be aquired. The rim would have to be turned down even after sizing was accomplished when using either of those. Case forming dies are about $175. Would I barrel up a rifle for myself chambered in 225 Winchester? Not a chance! I'd have to have a pile of new brass on hand. Brass fired in another chamber is never a 'shoe-in' in any other chamber, even after FL sizing. I've got a 6mmX45 right now that won't except FL sized brass that was fired in another 6mmX45 THAT WAS EVEN CUT WITH THE SAME REAMER! Could I buy a small base die and make it work? Probably, but why? No small base die available for the 225 Win. A custom sizing die? Reach for your wallet! That's not the only example I can site. It's actually pretty common,,,, guys figuring they'll just use the brass they already have even though it was fired in another chamber. If I wanted something different I'd look at the .220 Swift or the .220 Swift Ackley Improved. At least I could buy current manufacture Hornaday brass for that. (a die set for the .220 Swift AI will cost a $100.00 + and be 'special order' from RCBS) The .220 Swift will feed from a 700, no problem, and it's 'semi' rimmed. Don't know about the 225 Win
