A real gunsmith saw one of my projects and said that the barrel marks on the muzzle showed that I chambered the wrong end. He say that the button is pulled from the marked end to the unmarked and bullets should follow that direction.

But my .224" Lothar Walther bull barrel blank has no marks on the end.

It depends on which side of the equator you live on.

Douglas claims to mark the "muzzle" end of the blank to show the "tightest taper". To my knowledge Shilen makes no claim. Back when I was wasting time turning barrels, I would chamber the marked end of the Shilens and never had any problems. Who's barrel did you use?

Krieger laps in one direction and tells you to chamber it so that the bullet travels in the same direction.

In industry we mark all barrels so they get chambered from the correct end. You want the bullet to always travel in the direction the rifling was formed in, be it button, hammer, or cut.

As for your problem, I have no idea which end other barrel manufactures mark. You might want to call and ask.

I find that hard to believe! I think maybe he means he only laps from one end. Would that comment be true, does he pull the lap out and re-insert it from the same end as before?

I was always under the impression that a bullet always travels in the same direction,lol could,t pass that up. I kknow what you mean though.

I would agree. Were that the case he would have to make a new lap after each stroke and that don't sound like fun.

Most of the quality barrel makers mark the breech end of their blanks with information such as bore & groove diameter and an identifying number for quality control purposes. Most will also recommend cutting off at least an inch of the muzzle end because of any "belling' that may have occured during lapping. Reaming the chamber will take care of any belling at the breech end.

Every barrel maker that I know has a telephone. If there is any doubt about anything, just call them.

Now, why would anybody want to chamber the muzzle end????

From Krieger's website.

With any premium barrel that has been finish lapped -- such as your Krieger Barrel --, the lay or direction of the finish is in the direction of the bullet travel, so fouling is minimal. This is true of any properly finish-lapped barrel regardless of how it is rifled. If it is not finish-lapped, there will be reamer marks left in the bore that are directly across the direction of the bullet travel. This occurs even in a button-rifled barrel as the button cannot completely iron out these reamer marks.

It could be that they mean that the lay of the barrel is perpendicular to the bore rather than circumfrential. I understood it to mean that the bullet travel is in the same direction as the lay of the barrel, where "lay" is like the grass on a putting green which has a tendency to lay over in one direction and you can putt with the lay, against the lay or across the lay. But, it is conceivable that it is just that they mean that the lay is fore and aft in the barrel and bullet is not cutting across the reamer marks from boring the hole.

I had always read that lapping is done with short fore and aft strokes but thought that Krieger must have been doing it differently.

Frank maybe it isn't clear, but they mean the lap goes as Kobe says. I have seen them lap.By the way, Hart pushes their buttons.
