Thread: cold/clean bore shot

10" from zero sounds a hell of a lot for a cold shot. Must be frustrating.
Whats the velocity on the cold clean shot?
Is there a huge difference from the second?

I have never fired a naked bullet thru any of my current barrels as I use HBN to coat all my projectiles. It doesn't matter what state my barrel is in I don't have any issues with POI shift due to a cold or clean bore.
If my barrels are really, really clean I need a couple rounds down them before the velocity on a cold shot is where it is supposed to be.
But that lasts easy a 100 rounds without any major cleaning other than a lightly oiled patch if I have been out in wet weather.

10" shift would do my head in.
Have you let the barrel totally cool before you fire the second shot to ensure it is on its zero?
