Nor does any other barrel need to be "conditioned" if it's made right. If it ain't made right, why buy it in the first place?
Any time the hole in a barrel's made bigger, there's less resistance to the bullet starting down it and pressure will be less. So will muzzle velocity.
Every "rough" bore barrel I've shot produced better accuracy after a few rounds laid copper in those rough spots so subsequent bullets would not be unbalanced from jacket material being scraped off. Never ever had one that had accuracy get worse after copper fouling.
The most accurate barrels I know of all have the same bore and groove diameters all the way from lead to muzzle. No taper whatsoever. Good barrel makers lap barrels to less than .0001" spread the entire length of the rifling when the blanks finished. Fire lapping a barrel makes it taper tighter from its hind end forward. Borrow a Sheffield air gage then measure your fire lapped barrel.
Thank you Bart !!!
I was beginning to think I was the only one that did not abuse barrels. I have re barreled many barrels that had been abused one way or the other and hate to see a quality barrel like the Krieger Fire Lapped.
I know that seasoning or breaking in a barrel takes time but it is well worth it. (There is no free
ride) taking short cuts leads to bad things. That is the big difference between a good smith and
a bad one.
To save money a person that though he needed to lap a barrel used the rubber abrasive tips that
are used on a Dremel tool to "Fire Lapp" his barrel. When I bore scoped it, it looked like it had been through two wars. It ticked me of to see a fine barrel treated this way so I declined to re barrel It
not knowing what he would do next.
The logic is very simple, "ONCE YOU REMOVE BARREL MATERIAL YOU CANT PUT IT BACK" And if you taper the bore it is worthless. Barrel makers go to great lengths to Gage bore diameter and most
reject them if the barrel has more than .00005 difference end to end.
Gun smiths and barrel makers rejoice , this means more barrel jobs and faster barrel burn outs.
PS : I did follow the instructions to the letter and 5 min. between shots (1 hour and 20 min is plenty
of time to allow the barrel to cool for 10 shots. And everyone that wants to try it should, that way,
they can learn the hard way. I promise not to try and talk anyone out of doing this anymore In fact I should encourage it because it is job security for lots of gun smiths.
