Howdy folks. Slaving away here on a couple of .303 's and was wondering if there is a "law" of diminishing returns on cleaning these old war horses.Should I be trying to get every speck of copper out or just so nothing is showing on the patch. I usually just go till the patch is clean put some oil on the next one and then leave it.What are your guys thoughts on this.? Thanks again
How clean do you get your .303 barrel?

Some of these old war horses don't really need the copper cleaned out on a steady basis. Most of them shoot better with a little copper fouling. Just use Hoppes No 9 to remove the powder fouling and only go after the copper if your accuracy starts to fall off. bearhunter

Try electrochemical cleaning. If you poke around the net, there is lots of info. I made an electrochemical bore cleaner for under $10.
Its really the only thing that can eat through the layers of powder and metal fouling on these old mil surps, particularly if there is a lot of nickel fouling.

Wire. Mild steel uncoated welding rod. 1 1/2 v. flashlight battery. Rubber stopper skewered on steel rod. Stopper must be of a size to cork the chamber. Rubber rings, o-rings, etc. on steel rod to keep it from touching the bore. Bottle of household ammonia. A funnel which will fit the muzzle is a nice touch, ammonia will foam when current is on. -ve connection to rod, +ve to barrel. If it foams, the rod is not shorted out to the barrel. Foaming will start almost instantly, if the circuit is good. Let it run about 15 minutes, empty out, brush and patch, inspect. Repeat if necessary. I wouldn't get carried away with it, wouldn't use the process on a good barrel; a good barrel shouldn't need this anyway. The amount of crap that will be removed is amazing. Wipe the rod off between cycles.
I have had good luck with "WIPE-OUT" Brushless Bore Cleaner.....just be sure you have plenty of patches to run through.....it wouldn't get your bore clean the first time.....be patient....one has to remember the age of the rifle....you are trying to clean years of copper and powder fouling....
Took me over a week of soaking the bore of my 1942 Remington 03/a3 and my 1916 P14...and pushing patches through....should have seen the crud i pushed out.....the bores are clean now ! here is the e-mail address for the bore cleaner.
