Rifle Barrel Question

Hmm, good question. The problem with answering it is that is the fact that you are asking us to compare apples to oranges.

There are many types of steel: tool steel, stainless, high-carbon, lo-carbon, etc.

There are many finishes: bluing, bead-blasting, rust bluing, etc.

A stainless steel barrel can have a blued finish. A 4140 steel barrel can have a nickel, stainless, or even bead-blasted finish. The really salient point is what the actual metal of the barrel is made of and how the barrel is constructed.

Other things also affect the rate at which a barrel heats up: size, bore diameter, finish, fluting, and others.

Now, if you are asking for a stainless vs. carbon vs. chromoly vs. new-fangled wonder barrel barrels, that is a different question.

Are you trying to choose between two rifles or different barrel types? If so, please let us know and perhaps we can assist you better.

Hope this helps.
 
OK let me try again. I have read that the Ruger Mini 14 blued model has less accuracy loss after barrel heat up than the SS model. Can anyone confirm this? Opinions please. :D

There is a formula millwrights use to figure the expansion of steel .000006 per inch of material per degree of tempiture with a differintal between the material temp and ambiant temp. stainless is not much more, maybe .0000015 more expansion.
Hope this helps--Bill
 
I read somewhere that a heavy glass bead blasted barrel will disipate heat as fast as a fluted barrel and that a heavy glass bead blast on a fluted barrel is the best you can do in terms of cooling...

Can anyone find similar information?
