To recap, I was having issues with this one stacking first/third shots, and sending number 2 off randomly high left, low right, low left, straight high, straight to the side....really weird. Never repeated the same either. Then I did a good solid cleaning. And went and did this. 120 TTSX, 44.0 RL-15, 2.235" Ogive, 7-08: ![[Linked Image]](http://i154.photobucket.com/albums/s278/armed_ferret/gun_stuff/20140413_115425_zpsae0e9776.jpg) 120 TTSX, 43.5 RL-15, 2.745" OAL, 7-08: ![[Linked Image]](http://i154.photobucket.com/albums/s278/armed_ferret/gun_stuff/20140413_124827_zpsde2885d8.jpg) i think the tube just likes to stay clean. toward the end of the range trip today it started doing the 1st/3rd shots right on top of each other, with 2 a random flyer never in the same spot. so i just gotta keep it a little cleaner is all. not a huge deal.

How many total rounds through it?
This is a shooting forum, there is no place here for logic.

happens every 40-50 rounds. granted, it's still holding just over MOA (1.25-1.5ish) when it does it, but as you can see, that's still well outside the rig's potential.
the good news is, it's very easy and quick to clean. a single run of foaming bore cleaner takes care of everything and it's good to go.
even after it was good and dirty, and opened up a good amount at 100, it was pinging my steel at 300 (8x8) without fail, and that was a 12-shot string stopping only to put 3 more in the belly each time.
prolly end up going moly just so i don't have to clean it religiously.
tube has prolly 75-80 rounds through it? maybe 100, but that's a big maybe.

I have been using Moly (and lots of 120gr Barnes 7mm bullets) for a very long time and I really cannot remember the last time I thouroughly cleaned a rifle barrel. This includes my varmint rifles in 222 and 223 that see lots of bullets down the pipe in a year. All that to say, you are on the right track - both counts. Glad your rifle is shooting well for you now.

You may not be getting it completely clean with the foaming bore cleaner if it's opening up that soon.
Do yourself a favor and schit can the moly idea.

I've had a few factory barrels that behaved better after a few cleanings with JB when they started to act up. Now they don't suddenly go awry after a small number of rounds.

Yeah, the foamy stuff is handy, but JB is wonderful stuff when you need it.
What fresh Hell is this?

JB weld? Bore paste. It's almost as clean of a procedure as tearing down a small block.

Ive got a Beretta Mato in 7mm Mag that would do the same thing. After cleaning it would shoot the first 3 shot group around a inch then the next two groups would be three shots touching or damn near touching. After that it would open back up shots 9-12 would be around 2" and then it would just get worse. Didnt matter what bullet, powder or seating depth.
Mollyed up some 140 Tsx cleaned the bore to metal and laid down moly. Gun now will shoot under a inch all the time and usually better than that. Point of impact doesnt change as it gets hot. Ive shot over five hundred rounds since the last time it was cleaned.
So from my perspective I would try the moly.
I've always been different with one foot over the line.....

JB weld? That would be great. lol....... I do know a guy who left his muzzleloader outside and the bore rusted up very badly for the last 6-8 inches. He figured .50cal was close to 1/2 inch, so he took a 1/2" drill bit and reamed out all the orange gunk. No more rust, but no more rifling. He said it would miss a sheet of plywood from a stone's throw away.
Now with even more aplomb

Or Some Moly and no more cleaning. More than one way to skin a cat.

I would eat moly on toast before I would put it into another one of my barrels. Terrible stuff that often required just as much cleaning or more than clean bullets.
DBC replaced moly anywhere I thought it was needed, such as rifles for high volume shooting.

Not saying you are wrong Ive just had opposite experience than you have in the three guns I have used it in. Like I said more than one way to skin a cat. Good day.
