[markb317]

what is the bore size of the 40 caliber muzzleloaders?

:)Mark pn barrels measured .400 land to land and .408 groove there abouts.

Thanks Dave, I'm trying to decide on which I want to build a 40 or 45 caliber ML.

Last I heard was that Pacnor won't sell a drop-in barrel for .40. Because it can only be shot sabotless or with handmade sabots the guys shooting sabotless were complaining too much about looseness as the bullet neared the powder. If this has changed let me know.

As far as I know, that's still the deal, but PCNR is still selling 40 cal barrels. You just have to do the chambering yourself or find a smith that will.

A ML10-II with a PacNor 40 cal barrel is awesome! ;D ;D ;D Unfortunately there are no 40/357 sabots, yet.

could aways ask them to contour the "looser end" for the muzzle too.
