I think when Mike wrote that book he was aware of that possibility but he chose not to. He must have had his reasons. Another big reason is the exposed lube can easily pick up dirt and grit that you dont want going down your barrel. I suppose you could just not put lube in the top grooves but maybe that is not a good idea especially with BP where you never seem to have enough lube. Unless I was carrying loaded ammo in my pockets dirt or lint never has been an issue. I put mine in MTM plastic boxes and never had an issue. Once fired the bullet lube grooves are completely into the rifling before any burnt powder exits the case, so that wont be an issue either. I do fill all my lube grooves as I want a good lube star at the crown to tell me the lube is reaching the muzzle. I have Mike's book and pretty sure I saw pictures of loaded rounds in there with bullets seated fairly far out.

	I was sort of quoting from Mike V's book specifically what he said about the 45-90 that they could only get a 70 grain charge weight in it. I also shoot a 40-90 BN so was interested to see what he had to say about that cartridge. In the load specs for the 40-90 it says they used the full 90 grain charge weight and that with the 400 grain RCBS bullet , go figure right.
