I finally gave up on the 45's as I see no real advantage except the pac nors flat out shoot. So I pulled the 45 barrel off my 700 and a member sold me a 50 off one he just got . It has some light pitting (hey I only paid 30 bucks total) and in spots it feel like I'm pushing the sabot threw a piece of sandpaper but the thing shoots. I just wonder how bad does a barrel have to get before it doesn't shoot. I'm also debating shooting some powerbelts there her to see if it smooths out any. The rest of the story is that it's sitting in a sps stock, I have not done anything with the bdl opening at this point. I'm not sure that I"m going to do anything to close it up, time will tell. Sorry guys the 45 barrel is on it's way to hunter.

JB the bore using a tight patch and the sandpaper feeling in the barrel will go away and make loading over those spots easier. Start with 50 passes then after a thorough cleaning push a bullet/sabot down the bore and see if it runs down the bore better. If not JB again.

JB Bore Paste, non embedding. I start by oiling the bore with a Hoppes patch. Then smear the paste on a patch. I leave the breech plug in the gun and go from muzzle to breech down and up. Check the patch frequently and change out when it gets really easy to push pull. Follow up by cleaning the barrel with Hoppes or whatever gun oil you use. I then remove the breech plug and run a few patches down to clean up that area and clean the plug out.
I learned this from Sabotloader and it indeed works, especially helpful in tight TC bores.

Get a David Tubbs fire lapping kit, some full size lead conicals and fire lap the barrel. Use a reduced load to fire them. Follow the instructions in the kit by rolling 5 conicals in each grit, then load the conicals first from the breech, then the powder, put the breech back in and then seat the conical from the muzzle, then fire. If you do all the grits in the kit which is 3 the barrel should be real smooth. Mike

45 omega,
Thanks for the info I will bookmark this thread so when I need it I'll have if the JB won't fix the problem I will try the fire lapping that Mike refered to I have read about the fire lapping and it seems to be the "sure fire" no pun intended way of smoothing out a barrel. I have limited places to shoot so I will try the jb first.
rjhans good luck on smoothing your barrel these suggestions from these guys should put you on the right path.
Thanks for the tips,
Greenhorn

Follow the link. I've hand lapped several barrels and just finished firelapping one. Go slow. A little at at time, then clean up and shoot a test group, then lap again if need be. Might take 2 or 3 lapping sessions, more with a bad bore, but it works. I've bought some "bad" ml guns real cheap, like for cannibalizing, and turned them into shooters. You can look at Midway or Brownells and they have finer compound than Beartooth. Finer grit means slower and more lapping sessions but safer as you are taking less metal off and polishing more. 10 C:\Documents and Settings\Bob\My Documents\ML stuff\Beartooth Bullets Fire Lapping.mht |

I just did a .50 TC barrel today with JB. Barrel was spotless using a .50 rod and jag when I ran an oiled patch down and out. The picture shows patch #1 after 25 passes with JB on a patch pushed down the bore with a .50 cleaning brush. I repeated the process with one more JB patch for a total of 50 passes. I cleaned all the JB out with soaked Break Free patches. Gun definitely loads easier now.
I never tried fire lapping as this has worked well for me.

I've been using JB for some 20 years now its great stuff. Works great for breaking in new barrels also.

I've shot some rifles with pitted barrels and the only problem is they need to be cleaned more often and more thoughly. They plastic up easier and must be scrubbed out. The methods to smooth up the barrel with JB and/or fire lapping will work.
