Bill Large would sometimes concave the lands in a barrel and it looked good and the scoped 58 I shot at 399 yards was one of these and the long shots proved it worked.He did this by hand and it is easily seen.Does any maker today do that or are they aware of such a modification
Bob Roller.
The only way I know to concave the lands is to do it with a freshing stick with a domed cutter for the lands with a radius less than that of the bore. Very little work is required once the stick and cutter are set up.
That is the way Bill did it,just an additional "touch"to another good job.
