8mm-06?

Good to hear from you, Bruce. The more I'm looking into this, if there was as good a selection of 8mm bullets as .308 bullets this would (dare I say it?) be a better cartridge than the '06.

A friend sent me some of those heavy Lees. I really hope this works with them, the rifle seems to have a generous throat, I seated these spitzers pretty far out expecting to have to seat them deeper, but the slid right in no problem.

you could run about 20-25 paper patched bullets down that barrel to help clean it up too.
regular old white printer paper will shine it up pretty good.

the key is the type of paper.
think about 2000 grit final polishing only with 40-K of pressure pushing it down into the metal it just removes the high spots.
you don't want to get carried away with it, but it will remove frosting and a bunch of crud from a roughish barrel.
plus it's simple to do, water paper roll load shoot.
switch over to a cotton vellum and your good for about 5-6K rounds on a new barrel.
bright white titanium dioxide and clay type paper is more like 2-K,,, at most.
but 20-25 rounds will improve the appearance and finish on an old barrel enough you can see and feel the difference without it really doing any harm.

It just so happens I have some slightly under sized 8mm cast bullets to try this with. I understand how to make a template, just ordinary printer paper is easy. What kind of load are we talking about, would the standard ten grains of Unique work?

OK, my first foray into paper patching. I cut out the pieces yesterday, dampened them and wrapped the bullets while I was watching TV last night and they were completely dry this afternoon when I got home. I ran them through a .327 sizer with some graphite powder. I did no sizing to the cases, just flared the case mouths with a Lee universal expander. Loaded them with ten grains of 700X, most of them seated just fine, a few tore a little. I shot 25 of these, accuracy was terrible, but no biggie. I have the bore soaking with some Ed's Red now, I'm hoping that polished it up enough.

How many paper patched rounds should it take to smooth things up?

you can shoot it till you just have a shiny hole if you want, all your doing is saving 50 bucks on a tubbs lapping kit.
you probably feel a bit more smoothness with a patch already, if it doesn't feel good do a handful more with some juice behind them.

can't believe i missed this before and feel bad.

303 guy often said that a salvageable barrel might take 100 rounds to begin to show a load direction. I've found that typically they show up directions around 50 rounds .

A cheap new barrel takes more as does a really ugly frosted barrel .
A better lapped barrel or well used barrel fewer .

good barrels will shoot right out of the gate.
I have a couple that have taken 0 load testing, throw something reasonable in there with a good bullet and groups in the 1/2-3/4" range are showing up before the scope is adjusted.

well you gotta pay and roll the dice.
i really favor Bergara and Hart barrels, but i'm sure even they only have a 99% success rate.
i'd still close my eyes and point to the shelf for one of them over a carefully chosen factory Remington barrel.

At the casting bench in the sky. RIP Bret.
I think sometimes the barrels that took 30-50 rounds to start acting right were actually barrels that were set in stocks that need to get enough recoil episodes to settle the action into the stock.

Just a thought.
