Anyone done it themselves and what did you use?
I think i remember Greg saying way back he tried it in a 243 years ago.
what is the problem and what do you hope to achieve?
Id recommend using common sense and not firelapping your barrel
Gun has been bedded floated tweaked and twisted but it wont play the game, starts with an average group but progressively gets worse the more rounds through it, is gonna be a last resort with the fire lapping before gun gets put into a project status
I havent looked since throwing it in the cupboard yesterday but im gonna go and clean it soon so ill see, but that is what is being suggested.
In my experience lapping of any sort will not help it if it fouls badly. What make of barrel? TF?
Its a Sako 75
its fucked give it to me ;)
I was waiting for that from someone. lol
Is it coppering badly?
Can you feel any tight spots (or loose)as the cleaning rod is pushed threw?
Can you feel any bulge on the outside of the barrel?
What cal and any idea how many rounds down it?
Not really any tight spots the whole barrel is quite tight, no bulges that i can see.
Not sure how many rounds through it but my mate has never been happy with it performance since new.
Cleaned it before i shot and the first patch was very black but the rest were quite clean.
If its not coppering it could just be it doesn't like what your feeding it.
have you tried a few different projectiles and seating depths.?
A second hand barrel I have coppered,still shot ok but coppered.
I cleaned and shot cleaned and shot etc etc with no change.
Then cleaned spotless of copper and carbon and shot 10 blanks to carbon the bore and shot from there. Its been mint ever since:)
Not loading for it but it liked Winchester best and then i had to move to Hornady for lack of Winny, it started 3 to 5 inch groups with Hornady.
He used to run Norma in it as it was better than most but not great.
Take it to a decent Gunsmith & ask them to give it the once over.
It sounds like it has bigger problems than fire lapping with Final Finish will fix.
I read somewhere once that firelapping was the best thing out for barrel suppliers.
.270 Sorry
Found your problem :P
Just finished cleaning the bore and first 3 patches were greeny blue, quite allot for 13 rounds i think.
Ill check next lot of testing, i have got to pull it down and check a few other things with it now as a double check.
Shagged scope?

Tell him to get rid of it, he doesn't need it anyway, he neck shoots everything with his bushpig anyway :D
Not scope its a fairly new Zeiss, rings are good too, have done some more relief work on the bedding so will try again tomorrow.
Your right Josh he doesnt need it so i wont give it back. lol
If its a Conquest, I'd seriously be looking at fitting another scope to check - I've seen several conquests that were just crap!
It was fine on a different rifle.
Give the 1st 12" of barrel a scrub with JB bore paste..
Wrap a patch around a brush and give it a good wank :)
If its black as hell, then you got a bunch more work to do.
ADI powders especially create more carbon fouling that copper in most of my guns
So i broke the gun down again and re bedded it and re done the front pillar i put in it, tested it just before and it 2 holed at 50m with 3 shots after 2 sighters. I then stepped it out to 100m and fired another 3, the first went bang on target second 3 inches away and the 3rd 1/2 inch left of the 1st. I am thinking now that with a decent reload or factory ammo it will come in to under an inch. The only problem i have now is that i switched out scopes just in case Husky was right and the scope was the issue so i still need to prove that as well.
P.S: I still hate .270s
