Wayne,
If I have all the taps needed, ( I know I don't have all the metrics ), I'd make 'em to demand and ship 'em for like 2 bucks to cover shipping, sized to fit a 3/8 drill on the shank end, mebbe even 1/4.
Yeah, I can see where it IS possible for the hammer to not hit square. AND to ding the nipple so it is parallel to the hammer face. That would be good, in a way. Now the hammer hits it square. But, we do pull them to wash the gun, don't we, and we don't number them to go in the same chamber. That means that the nipple that is flat to the hammer last shoot might be in the next chamber, next shoot, and the "point" is in the wrong place.
I gotta see if there is anywhere to find the inside diameter of the different brands of caps. Regardless of the post above about manufacturing tolerances, I think the little copper cups are formed within a thou, for that brand. Not gonna buy Rem 11's with 5 thou diff from tin to tin. Rem to CCI, mebbe 5 or 10 thou difference, brand to brand, same "size".
I mentioned that the CCI 11's are a b****h to seat on my '60, and Rems slip on and grip real well. So, CCI IS smaller, mebbe even thicker copper. Both fall off my Pietta Rem, 'less you squeeze them, and hard.
Ah, well.
Cheers,
George
