i read an article awhile back in rifle shooter about using abrasive bullets the first time you shoot a new barrel...., basically they have a mild abrasive coating on them that helps smooth out any tool marks left in a new barrel

anyone have any experisce or kno where you can get these bullets?

according to the author he finds that using this pratise on a new barrel improves accurate barrel life by up to 30%:eek:....
 
I remember reading an article years ago about Fire Lapping which is what I think you are referring to here.

Firing these bullets with the abrasive on them is supposed to take out rough spots in the barrel. I have not seen them advertised for a long time. Don't know if they are still available or not.

There may be better ways to take out tool marks now. Cleaning pastes or ??

Maybe some other people have some ideas on this subject.
 
I think what you are looking for are called tubbs final finnish system , they are advertised at cabelas , whether you can impot them may be another story . I talked to a b/r shooter about them this past summer he said he haden't used them himself but knew of a few people that had and were quite happy with the results . As for myself I prefer the old stand-by method of barrel break in shoot one clean , shoot two clean and after a day at the range and a bunch of ammo later your finnished and beside getting a bright shiny smooth as glass bore you also get to spend a relaxing day at the range everybody wins!!!
 
Google "fire lapping" as mentioned. Lots of articles out there and the opinions are pretty split. (Has there ever bee a clear answer to anything on the net?)

Personally I think that it would lead to something like early throat erosion because thats where the abrasive would cut the fastest.

If you have a barrel that you think is that rough look into hand lapping. Some barrel makers do it so there must be a way to do a nice even polish using a lead plug and some rouge or something. I haven't run across a process that I like well enough to try it yet.
 
Brownells sells the bullets you are looking for there are five different grits or whatever you want to call it. they can take the dark out of an old barrel. Lapping compound on any bullet also works.
 
CAn't think of anything more ridiculios than blowing abrasive up the bore behind 60000
PSI DON"T buy into all the bull that gets printed in the magazines and online. The only lapping a barrel should recieve is by the maker when its produced. And then it can be carefully controlled by someone with experiance. MUCH BLACK MAGIC AND WITCHCRAFT IN THIS SHOOTING GAME.
 
Just shoot 500 rounds through the barrel, should do a pretty good job of cleaning out any kind of rough leftover bits.

its not THAT abrasive its an extrmely mild abrasive designed to remove tool marks left in a new barrel from a manufactuer not a custom barrell that is lapped to perfection.....

it says they can also be usd to "help clean up an old bore"
 
200 grit 400 grit 800 grit and 1200 grit embedded jacketed bullets. doesn't sound like extremely mild abrasive to me. Any thing that will remove tool marks will indeed be very abrasive. Go ahead and wear your barrel out!!! Some of those 200 grit babies will work the fastest. Lifted the grit sizes from the NECO firelapping website by the way!!
 
My experience with Final Finish

I have used final finish to clean up an old bore on a Marlin 1894 made in 1900.
It did a great job ! :dancingbanana:
That being said, I am not sure I would use it on a new rifle. Below are 3 good links on the subject. The first is David Tubb on Final Finish, obviously pro. The second is a great anti and the third a how to do hand lapping. So read and make up your own mind. :confused:

I found an article written by Mike Venturino & a good friend of his has a company making different products.
One of the products is an assortment of fire lapping compounds.

interesting this seems alot more complicated than it did in the article i read;) i think ill just stick to the "shoot n' clean" method....:rolleyes:
 
I've used the Neco Fire Lapping Kit many time on problem barrels, that is, rough barrels that fouled too easily. the system works.

Regarding the coarser grtis, yes, 200 grit is coarse but it is embedding in the bullet which is softer than the barrel so the effective grit size protruding from the bullet is much less than the diameter of a 200 grit particle. Also, you only fire 5 -10 bullets with the coarsest grits, depending on how bad the barrel is. So in accuality, think of perhaps 400 grit abrasive cloth being rubbed down the bore 10 passes and that is probably equivalent to the coarsest stage of the process.

Yes, the throat is part of the barrel that is most subject to wear. I found this particularly so if using lead bullets because they "upset" more than jacketed when they hit the rifling. I will only use jacketed bullets when fire lapping.
 
I have fire lapped many barrels with lead bullets at about 700 fps. Even with top quality match barrels, it is easy to tell a lapped barrel from non-lapped when cleaning.

Fire lapping tends to move throat forward a bit.

This process could have a bad outcome. I suggest you just breakin by a fire-clean process.
