I'm using the Lee .225-55-RF design to p.p. simply because the mould was relatively cheap, as am I. The boolits drop .227" - .228" as cast and I'm not sizing them to bore diameter but am wet wrapping them as cast and then sizing them in a Lyman .225 die in the Lyman 45 sizer w/o lubing them. I've unwrapped a couple and miked the driving bands and they're consistently .222" which is .003" over bore dia. of the .22-250 I'm going to try them in. The wrapped, sized boolits are miking .226" and are a twist fit in the case necks of fired brass.
My question is: With the core being roughly .003" over bore dia. , is their any chance of accuracy with these booilts? The rifles being used are accurate with both j-words and the naked boolits I've run thru them.
