I was impressed with chopperheads Safari Arms.The flint sparked every time, fit and finish are excellent, the balance is somewhere between a T/C and Lyman.We had to knap a perfectly good flint after ~ 30 shots, we couldn't wait any longer to show to do a demo on knapping.
As you can see the locktime is as fast as you can expect, all I did was cone the vent liner and drill it out to .067", (poor mans white lightning)
Cheers nessy.
