Tune ammo?

[CEDaytonaRydr]

Resize a brass and make youself one of these:

insert a bullet in the mouth just barely and slowly push it into chamber by hand till dead stop, carefully push out with a rod and measure the ogive to the base length and that's the length at touching the lands of rifling (for that particular bullet). Seat the bullet into the lands or off the lands to 'tune' for the best seating depth..

Well, you learn something new everyday!

Thanks man! That's a great idea. I guess I can stop using layout dye and going nuts trying to measure the point at which the rifling engages.
