SS barrel for a bench gun
- Thread starter CV32
- Start date
i have always had the 11deg target crown except in a factory savage which had the recessed counter sunk one i am not sure there is going to be a difference in them as long as they are both done right and there are no burrs or anything to effect the bullet when it is leaving the barrel!
as for the finish to the barrel it is a matter of taste would you like the bling,bling of the polished look or the subtle look of bead blasted barrel!
i like the polished look because i find it easy to clean.

Polished, matte brushed or bead blasted? Your rifle, your choice, its just about appearance.
For a crown, either a shallow angle like 11 degrees (or 10, 12, whatever, it isn't going to make any difference), or 90 degrees stepped and recessed. Either sets the crown into the barrel a bit to protect it, either works.
If your 'smith is experienced in making BR rifles, he will have a preference. Why not just ask him?

No difference either way. The finish is purely esthetic, the crown is a matter of what the gunsmith does best. I personally build all my rifles with a polished finishes and 11 degree crowns. I cannot defend it from a functional perspective.
I am not sure but isn't most formal benchrest shooting done under a covered firing point? I shoot fullbore outdoors so glare off the barrel is something I don't want. I have mine bead blasted.
My understanding about the 11 degree crown was that is was tested to be the best crown for shooting boattailed bullets. I don't think it really matters as long as it it concentric to the bore.

Matte or beaded is less refelctive, and cheaper. As above for the crown. - dan

Most B.R. shooters prefer matte. The rough surface actually has more surface, so it cools faster. If I get one thats polished I bead blast it!
If done correctly none of the choices will affect accuracy...
A finish much like the finish on a pre turned blank is fairly polished and is fine left that way...(cheapest). A flat crown or a slightly recessed crown is the quickest...(cheapest). If you want it to cool the quickest paint it flat black when you are done.
I much prefer the crown to be finished with a piloted 60 degree reamer... it is very quick to do and can be "touched up" later very easily. It also leaves a very smooth burr free finish.

This crown is very easy to do and as accurate as any.

One of the best pieces of advise I was ever given was to let the gunsmith determine the type of crown for your barrel. A correctly cut crown trumps a poorly cut one and a particular gunsmith will probably have a preference based on experience.
