The spool is like it left the factory. This rifle fed the 6mm int. before it went to Pederson. The Int is larger dia than the 6.5 but there is enough clearance for it in the spool. Do you have one of these rifles that I could compare mine to. If I were to build another it would probably be a 35 Rem with an 18" barrel. Would have to modidify the spindle because of bullet dia. I changed from 6mm to the 7mm because the actions slow lock time wasn't up to the ctgs potential. It is pretty and smooth but not as eficient and strong as my Arisaka.
