I've just finished my first mould. It uses the first 10mm of a 308 case as gas check.
A bit scruffy but works decently.
The aim is to shot the bullet subsonic in 458 win mag loaded with TinStar N32C, that fills the case nicely and no need for a filler.
As the purpose is hog hunting an expanding design is preferred to secure expansion, hence tin alloyed lead is used.
This mix is to soft to work with higher pressures than 27000 psi, wich makes a GC necessary.
Secondly the lower pressures from the gas when it exits the muzzle seems to lower the noice, compared to slower powders with lower chamber pressures but higher muzzle pressure.
Any hints an tips of improvements much apreciated.
