A friend of mine shown me this round.I tough it was a fireformed 300 Lapua,but it has a slighty longer neck ( and a different shoulder angle,I think) compared with the commercial 300 Lapua case.
Can you identify this 300 Lapua wildcat variation?Does it have a particoular name?
Left:commercial 300 Lapua case,neck lenght:8,69 mm
Right:the unnamed wildcat,neck lenght:9,39 mm
case lenght and other diameters are the same,so the shoulder angle should be sharper in the wildcat round
