“Learn how to make a lapping head out of some soft metal that matches your bore and groove profile. Then make one”

Bart B. teach him, show him, some of the equipment you are pushing cost $3,000 and up.

Wyop, as you know anyone that can lap a barrel is not much of a barrel lapper if he needs a micrometer to measure the barrel diameter for consistent diameter, then there is that part where Bart B. says

“Buy an air gauge with its gauging head matched to your bore and groove profile, or, buy a hole micrometer accurate to sub 1/10,000th inch long enough to reach the middle of the bore from either end”

When I slug a barrel the weak pass out and the strong get dizzy,

“Learn how to make a lapping head out of some soft metal that matches your bore and groove profile. Then make one”

I use universal fit all material that matches all bores that automatically adjust to groove profile and bore diameter.

Then there are (us) casters that can roll their own, then there is the Internet, for sale, lapping bullets, not a fan but some swear by the process.
