Slugged .348

[BrushBuster]

When I slugged and measured the bore on my .348, I got the figure of .345 max. dia.  Is this unusual, and what would be the ideal cast bullet dia. for me?

I haven't slugged a barrel in a long time and I'm not too well equipped to measure the slug.  Not to question you but are you absolutely sure your bore is totally free of fouling?  Of course I'd doubt you'd have .003 of buildup but had to ask the question.  I'm getting to know that you are mighty careful in all you do.  :grin:

Then, from my reading it seems there is a continget of casters who prefer bullets of .002 over bore diameter.  

Have you posed this question to Veral?  I'm sure he'll have an opinion.  

I'd consider slugging my 348 but I don't have a cleaning rod I want to pound on that hard. Maybe I can find a hardwood dowel at the store.

Dand, this is such an important measurement that I think I will go through a more intensive cleaning process before I arrive at my final figure. The bore appears squeeky clean, and I know it has not had more than one box of bullets through it. The lead slug travels easily through the entire barrel, and the lands are clearly defined.

I have read that industrial strength ammonia (10 percent) is a real effective copper remover if your careful with it and don't leave it in place too long. I'll try something like that and track down a micrometer instead of my trusty vernier.

I use Sweet's 7.62 a gel bore cleaner with a lot of ammonia.  Right now I'm trying out some Wipeout bore cleaner and it really attacks copper.  Don't know what the stuff is but it doesn't smell at all.  Its a foam and if there is copper it comes out as dark blue/ purple on the patches. You can leave it in the bore overnight.  And I use JB bore paste some too but hate to on a lever gun where you must work from the muzzle.  Good luck and patience.  Sure would be nice to have some of the real experts chime in.

Maybe you should ask about your bore diameter on the Lever forum.
