RE: Just watched a Hunting show Ruger 375
Since whendoes a bottle necked cartridge not provide positive headspace? Headspacing off of the shoulder and case head is a far better way of doing it than with rims or belts.
I will give you that tapered cases feed slightly easier than cases with less taper but I haven't ever seen a properly made riflechambered fora full length bottle necked cartridge fail to feed due to the case not having "excessive" taper.
