Hi guys. I've got a Green Mountain replacement barrel coming for my T/C Hawken, for better round ball shooting. At any rate, is there anything in particular I should do with a new barrel to break it in right? Season it? Treat it?

I've read all sorts of wild stuff, but sort of wanted a reality check. One suggestion I heard was to clean it up, then fire the first two patches soaked with valve lapping compound, rather than the more customary lube. Then repeat cleaning step. Voila, instant barrel polishing, deburring and break in, in only two shots.

From a theoretical point of view, I'm leery of treating a brand new barrel with abrasives. I can see where it might work, but I can also see where it could only create a zillion tiny little scratches for fouling to hide in. Any input?

I also seem to recall someone else saying not to swab it too often during the first few shooting sessions, as that would slow the break-in process.

Still another person recommended never using a bore brush to clean it, but only patches. Said that the use of the brush prevents the barrel from "seasoning like a fine cast iron skillet, the way it should."

This is actually going to be my first new BP rifle barrel. Given the nature of BP, the old saw about how well one cares for one's tools dictates how they take care of one holds even more true. Kind of exciting, actually, like a blank canvas.

I would just shoot it as you normally would if the accuracy isnt good after trying several loads you may want to use some bore paste on a patch to get it to break in faster but would clean well afterwards before shooting again. the manufacturer of the barrel could probably give you the best advice as they know how well they finish the barrel and wether it requires any type of break in or not.
 
Ordinarily, there shouldn't be any need to do anything to break in a new barrel unless you notice something wrong like if it's cutting the patches. That would be very unusual for a new GM barrel though.
I would just shoot it with moderate loads and get familiar with it before doing anything to it.
The less wear and tear on the bore the better.
There's less abrasive Hoppes Tynex plastic brushes, and I'll put masking tape over the exposed threaded section where it attaches to the rod.
Just clean and maintain it well.
When & whether or not to swab between shots is personal preference.
Let us know how it shoots. :)
 
Agree completely with bejay and articap with one caveat (that you've already mentioned): clean it thoroughly before shooting.

Seasoning is an old wive's tale - steel rifle barrels are not cast skillets, no matter how much one wants to wax eloquently about 'micro-fissures' and 'tiny pores in the metal'. Call GM and ask them about it.

And yes, let us know how it shoots.
