Well I got my new Lyman Trade Rifle today and its not a 5/8 flint like my Traditions pistol. Double ended saw cut and pretty thick, looks to be 5/8 x 3/4 the spec's say .6 x .8 x .2 thick. I have some spares ordered. Pretty impressed with the rifle, and it included a cleaning jag attachment and a extra rear sight with elevation adjustment that I will install instead of the fixed one on the gun.
Now to make sure my patches and the rest are ready for the next range visit!
