Moses on a moped: ROUGH Bore!

[rduckwor]

I have a little Mossberg MVP that is a play/excuse rifle. Had it for a short while and I have shot maybe 150 rounds thru it.

Went out yesterday to run an OCW with some new plinking bullets and it shot very poorly.

Slung bullets all over the paper.

This morning I decided that I need to do a detail clean before I started varying the other variables. Well, two hours later and maybe 70 patches, I finally got the barrel clean.

I don't have a borescope, but I would sure as hell like to see the inside of this barrel.

I realize it is not a precision rifle or an expensive rifle as things go, but holy hell, they must have rifled this barrel with a drill bit.

Hopefully it will slick up a bit as I shoot it.

Tubbs final finish system may be just what that bore needs

Well Buddha on a bicycle, that's disappointing. Had you cleaned the bore at all before? Just curious, it obviously shouldn't have degraded that quickly, even with no attention, IMO.

Elijah on an Elephant! It sounds like that thing needs some work. This is probably one of the few barrels that require a break in process.

Jumpin' Jesus on a pogo stick! What kind of ammo did you run through it at first? Any chance it may have been corrosive?

 

[rduckwor]

Well I bought it used, so I can't answer the corrosive ammo question, but I doubt it.

I have run commercial as well as hand loads thru it. It gets a light cleaning after each range session and most were low round count sessions, <30-40 rounds.

I think I will order a Tubb's kit Monday and see if I can't smooth things out a bit.

Thanks,

It used to take that many patches with Butch's on a Remington . Now i use boretech and it takes 11patches, what solvent are u using?

Wipeout for copper and Breakfree for the carbon/general grunge.

Thor on a trolley! It's a bummer that it's that rough, I was thinking about getting a MVP for my 223 mess around, hope everything smooths out. You said you used new plinking bullets, have you used them before and tried them in another .223?

No, this was the first outing with the plinking rounds.

I will get some Tubb's bore honing rounds thru it and then start anew after assesing the results of the Tubb's stuff.

It will be interesting to say the least.

Its a handy little rifle and lots of fun. I bought it as an "excuse" rifle in case things went South and the Mforgery had to disappear if you know what I mean: "But .gov, it's a bolt action hunting rifle. I have to feed my family." Yeah

You may be cleaning to much. Over cleaning can degrade your barrels life span. I usually let mine go until I see a drop in accuracy.
If you want to run a bore snake thru it with some light oil thats usually OK but I don't see the point in cleaning until you actually need it.

well with him saying that he's only put 150 rounds down with it... I hope the barrel can hold up to 5 or so cleanings. I mean the 3 things with these problems that I would think of is 1, scope/mounts problem... 2. The bullets he were using either need a faster twist or their center mass aren't correct... 3, Is the crown messed up?

These are usually the problems I've had to deal with when I had to look at someones rifle for them. I also deal with people who get most of their information about guns through a video game rather than anything, so I'm not used to dealing with people with people who know the usual checklist lol...

What type of solvent are you using? Two hours and 70 patches seems like a lot.

 

[rduckwor]

O.K. The light cleanings I referred to were nitro solvent and a bore snake at the range w/ a warm barrel. I understand that over cleaning can be a problem and I shoot until accuracy falls off too before serious cleaning take place.

Serious cleaning consists of Wipeout for copper removal, nitro solvent and patches as well as Breakfree for grunge cleaning.

As far as the scope mounting, crown, etc. I have shot <1MOA groups with the rifle before this latest cleaning episode, so likely those are not issues though they will be looked at as well.

This cleaning was a baseline issue so that I can rule the barrel state out before moving forward. The quality of the plinking bullets will be examined in the future as well.

Thanks for the suggestions.

I'll keep you posted.
