Thread: Cleaning old barrels

plug muzzle end with likes of tissue paper and spray crc in from action end till you cant get any more in...muzzle down over night then try scrubbing it out again....be carefull to keep rope to centre of bore and dont rub on edge as this stuffs crown/accuracy real quick.
you can use rod to clean just slip bare rod in and thread brush in at action then pull it back out....bore snakes are just too easy .

Or Mitch Maxberry has a heap of ex target 30 cal barrels ranging from good to excellent he can re chamber. Did my Savage 99 in 300 Savage for bugger all.

You could try electrolysis which would leave a clean bore without any copper or powder residue or lead or rust in the pits, so it would copper-up within a few shots anyway. Best idea is nor-west's, an ex-target barrel, slimmed down and trimmed-up; it would possibly be a more accurate rifle than when it was new.

Will give this Mitch maxbury guy a call tomorrow and see what he says about a rebarrel job,sounds like the best solution.

Try some Phosphoric acid for rust removal, Guggle it!

Phosphoric might work but the inside of the barrel will be parkerised and that isnt shiny.
Sell it to a pig hunter, the accuracies way better than what they usually require so it could be marketed as a target pig gun.

Yep but you can repolish it with FMJ projectiles and brasso

Dont use abrasives like Autosol or brasso as mentioned in earlier posts. For rust you could try something like this...SCA RUST CONVERTER - 500mL - Supercheap Auto

What projectiles are you using. I've battled with hornday's fouling my chrome moloy barrels for the last few years until I tried other brands and problem went away. Thought it was a bad barrel until I got a second rifle and same problem. Gun slick foam has been great and takes the carbon out to. I still use hornadys but the gun slick takes care of the fouling although if I've fired a few more rounds than usual I need to do it a couple of times and give it plenty of time to work, 30-40mins each time

You need abrasives to get a decent change. It's pitted shooting a 4 inch group at 40 meters. it's fucked anyway, it won't get worse from a little scrubbing. And if it does you loose a 4 inch group at 40m. Just re-barrel.

Tried fiocchi factory ,Winchester factory and hornady interlock round nose in my reloads,all 150g.might try some heavier pills one day..over the lack of accuracy for mow so back in the safe it goes.might flick it on and just use the ruger 77/44 for the wet weather hunts,it has open sights and my reloads shoot just over 1in at 50m.

@The bomb,

Interesting problem. Electrolysis will dissolve everything usual out, and the rust. How did the bore slugging go?

Been using a chemical called Metal Rescue for some work stuff, certainly dissolves rust, you can get it in Bunnings for about $50,
If it's as bad as you say I'd be tempted to give it a try,

Not tried slugging the barrel.what do I use and what does it tell you?

Anyone in the market for a do upproject?
