feed angle
The first magazine I measured was a seventy year old Scovil,that was 20 deg.
on the money,then all three different types from modern manufacturers and
all regardless of configuration were consistently 20 deg.as well.The approach
angle then being the same,the variables are a)spring pressure b)point of release.
Not all manufacturers seem to subscribe to the raised bump theory and the skirted type follower appears to be more of a reassuring feature than a useful
one,interesting to mention is the the convex type which appears in some Wadcutter type magazines.
