I have a 2 die (Dave) Corbin die set in .452 dia. The core seat die includes one flat base internal punch and four external punches: an inside jacket. a hollow point, a Keith, and a 3/4E round nose. There is also a 3/4E point form die in the set. Note there is NO core swage die. I've been using the same core swage die for401's, 406's, 430's, and 452's. Price is $383.50 shipped any place a flat rate will go. Insurance is extra and highly recommended. PM with inquiries...
