While following the direction in the BTB tec manual it says the bands of the bullet should turn nearly jet black with lapping coumpound. When coating my bullets I could only get the top and bottom edges of the driving bands to turn black, the middle of the bands had hardly and color at all.
Is this normal or unimportant, or am I doing something wrong?
If this has happened to anyone else please let me know how it affected the outcome of your lapping project>
Thanks
