I bought a NIB 35 RD mould on another forum and got it all cleaned up and cast up a few today from my hunting alloy of 50/50 WW to soft ,This was my first 6 cav. mould took a while to get up speed pouring with a small lyman laddle But I learned that poor 3 and refill and do the back three works out OK. Once I got that big mould up to temp it cast some nice looking bullets . Sorted out the culls and put the calipers on a few of the keepers and the base band was .360 and the top band and bottom of the nose was .360 but the middle TL bands are all only .357-.358 ?
Firstly can they be used like this ? I normally size to .360 my bore is a measured .358 . Second ,besides lapping anyway to correct this ? More tin in the alloy maybe? Beagle the back of the mould?
