Beveling cylinders

[arcticap]

Not to mention if it shaves a ring you might lose a couple grains, even a precisely weighed ball would be useless if you end up cutting two grains off one, three off another, etc. and I would assume a professional like yourself would want them to all weigh exactly the same. And of course each chamber might do it slightly different, so it would (at least in theory) improve consistency on the ball going into the chamber.

Any thoughts on this?

I'm not going to say that chamfering is necessarily a problem because it doesn't have to be a problem. But how well the chamfering is performed could be a problem.
For instance, if the chamfering isn't done concentric to the center of each chamber, then chamfering may not be advantageous.
Locating the center of the chamber and then being able to execute the perfect chamfer is not unlike making a perfect crown. Since an imperfect crown can affect accuracy, then perhaps an imperfect chamfer can make for a less perfectly loaded ball compared to a non-chamfered chamber.
Folks can have their opinions for and against chamfering just as they can have opinions about certain types of crowns.
Another example would be coning a barrel. Some folks claim that coning a barrel using a coning kit does not negatively affect accuracy and only makes loading easier. While others may not be absolutely convinced about the accuracy results after a muzzle is coned. While a coning job may not necessarily come out badly, I think that there's the potential for it to come out badly.
A small amount of chamfering to eliminate burrs may be a positive change, but at what point if any, does excessive chamfering negatively affect the angle of the ball while being loaded and negatively impact its shape?

Back from Tombstone, had a great time, highly recommend it. Hear are pics of the cylinder I beveled and the tool I used, a dremal drill press, the cone shaped grinder was something I had lying around, I placed the dremal on the lowest speed. I fill the cone self centered its self on the chambers I went slow lightly taping the cylinder and used a ball to sit on the top checking until I got the desired effect. I used the most worn cylinder I had to do this with, and have 12 extra so if I messed it up no big deal, I am out 50 bucks, The result was more than “I think it shoots a little better” it was a dramatic change for the better, I suppose there could have ben burs or some other defect that may have been solved by the process, just don’t know, but I have been spending individual time with my cylinders, and they do very in how they shoot, and I know you could have 2 guns come off the line one right after the other and fit by the same person, and one might shoot great and the other not so good, it is just one of the mysteries of mass production, and for $200.00 retail no one is spending all day on them, they are test fired to make sure they function safely and that is it. It seams this like many other technique, used in the quest for the perfect shooter has more than one path and opinion,and to me that is why I love it so much, keeps me thinking, great fun, great forum, I keep tabs on some of the other forums but this one I check several times a day, Thank you all.

so did Colt. Chicharonnes is absolutely right, and got it in one.
