David Tubb Final Finish Bore Conditioning Ammo
 

Has any one tried this conditioning ammo and how did it work for you? Will it void your factory warranty?

RE: David Tubb Final Finish Bore Conditioning Ammo
 

I don't know about voiding warranty but I have seen and heard mixed results about this product/method. I guess I'm just too old fashoned,but I ALWAYS lap barrels by hand,and have done so in this manner for the last 25+ years. When lapping a barrel by hand,I can seem to feel every burr and "tight" spot,and this procedure has NEVER failed to give me positive results.

It will void it on custom barrels. They specifically tell you not to fire lap barrels.

Why? Are you having trouble with your gun?

I'm not having trouble with my gun. I bought a new Kimber Montana 300 wsm and have been reading about breaking the barrel in. There site says this is an easier way to break a new barrel in.

A fine gun like the Kimber, don't do it. I bought tubbs bullets and reloaded for them to smooth out a bore, and ended up littlerly ruining a bore and had to rebarrel a gun. some had better results but I know I wouldn't risk it for a nice new gun.

I would not use final finish as a break-in substitute, that is not what the product is really intended for.

I have used the product on a match barrel that needed a little work and it performed as advertised and was happy with the results.

For barrel break-in stick to standard break-in procedures.
