I have a 270 Win built on a 98 action in 1947 by WA Sukalle. It is a beautiful rifle except for the size of the chamber. The mil spec magazine does not allow me to load closer to the lands. My question is should I have the barrel set back or the magazine enlarged? I prefer to get the bullet as close to .030 as possible. When loading 139 sptizers I am over .100 from the lands. Winchester PP because of the different ogive shoot better but as a reloader they are hard to come by.
