hello everybody

I have a problem with my gun. See, I am a new guy and just got myself cheap 150$ .22lr mossberg model 152 rifle. It came with cheap scope too. So, naturally I took it the range right from the place I bought it, never cleaned or oiled it but started shooting right away. Results were great! by the end of first hour I got my grouping down to an inch on 100m. I have some shooting experience but its been years since I ever shoot anything. So, I am a happy camper, go back home, clean my new toy and oil it and take to the range next day and all of a sudden some shots are out of wack. there will be like 4 out of 5 in a good group and one way out. Or more. Then I decided to re-sight it to 25 yards for grouse hunting (I think thats more likely range I will shoot em at) and grouping sucks even more.

Then I bring my rifle back home and clean it and see through the barrel and I think rifles are not there for the first 1/3 of the barrel. Now is the question - was it "shot out " ( I have heard this term) before I bought my rifle? Or is it possible that rifles are just covered with led? I mean do I have to re-barrel this rifle or is it recoverable? Was it me doing something wrong? Grouping was awesome on my first day of shooting, what happened between now and then? How many shots can I put through the barrel before I have to clean it? Comments are welcome

Thanx beforehand and sorry for lenghthy post.
 
I have never seen a shot out .22, with low pressure, low velocity lead bullets it's not going to damage the bore. I'm sure it just needs a real good cleaning.
Check the take down screw to see if it loosens up when you are shooting. If the action isn't snug, your groups will go to hell. Same with the scope mount and rings.
 
$150 for the gun and scope. A new barrel will cost about $500, you do the math. It would take 100,000 round or more to shoot out a rimfire barrel, unless you are in rapid fire mode.
Clean the bore first with a good cleaning rod and a bronze brush.
Take the action out of the stock and make sure there isn't any oil between the action and stock and the stock is bone dry. Put the action back in the stock and tighten the bedding screw. Check the scope mounts. The scope could be the problem, change that out next if the problem isn't solved.
Keep the action clean, forget about the bore. I will put 1000 rounds through mine before I even think about cleaning the bore. Then is take a few fouling shots to get it back grouping again.
 
Sounds to me like you have a leading problem here. I have a 152 series Mossberg, and it is an accurate Semi-auto. To get rid of that lead, you need to avail yourself of one of the lead removal methods and get that lead that is filling in those grooves. I like metallic mercury, but since it is a restricted substance, it can be hard to come by. If you can find some though, it will take that lead out lickety-split!! There are mechanical means to remove lead out there. Whatever you do, do NOT run any stiff steel brushes in there to get it out, you could wreck that soft rimfire barrel. I only clean after 500 or more rounds, even with my expensive, super accurate 22 rimfires. Regards, Eagleye.
 
If you did need a new barrel, Numrich has them in stock for $43.25 US, and will ship to Canada, I've dealt with them a few times, great service.

I happened to have some mercury, from my gold prospecting supplies from years ago. How do I clean barrel with mercury? As far as I know mercury does not get attached to about anything, can't moist the rag with it or anything like that.

Any other lead removal methods? I couldn't find anything yet on this forum... Give me some ideas or key words to use in searching this forum please.

And thanx again everybody. Yes, there is some oil between barel and stock (I think I put it there accidentally). And some loose screws.

Thank you Ross, I just googled em and looks like if everything else fails I will just order a new barrel.
 
Just give her a good clean, and tighten everything up.
I have never seen a shot-out Mossberg .22, but I have seen some that have never been cleaned. :eek:

Also Havlin might have spare parts if you need some, and are great people to deal with. :)
 
Shooting an old gun with a dirty, may be slightly rusted barrel may have
caused leading, especially if you done rapid fire (excess heat).

GB bore paste is an abrasive cleaner wich can remove lead. It is not
supposed to harm the steel of the barrel but I only use it on extrem
case. If you use it give more scrubing on the dirtier third of your
barrel following instructions on the jar.

I second: don't use a steel brush in a soft steel rimfire barrel!!!
 
You plug one ond of the barrel tight. put about 2-3 oz of metallic mercury in the other end. Plug that end also and then tip the barrel back and forth while rotating it. The mercury will absorb the lead in any quantity, and leave the barrel lead free. Dump the mercury/lead amalgam out of the barrel into a tin or jar, and discard it environmentally safe.

One other thing worth mentioning. There's a common mistake that even experienced shooters sometimes make. Make sure that the sandbag or rest you're shooting from is supported by the stock not the barell. Ya I know it sounds stupid, but I'm sure we've all done it. Your accuracy will go to crap when this happens. It's really easy to fix. Just something to look out for, before going to new barells, mercury poisoning or other more complicated suggestions. Sometimes it's something simple.
 
x2 for the jb paste I give all new and new to me guns a solid scrubbing with it.

Mercury Holy Cow ! ... That does explain some of the posts around here :)
 
I brought this old thread of mine because I think I found the right answer to my own question. It turns out rifle was shooting extremely well only when I fold down that foldible forestock piece. It is designed so that when folded down it wedges the barrel throwing off the point of impact. I was slightly pissed with that fact and removed that thingey and thats why grouping opened up.
 
Glad to hear it's resolved. Try putting a shim in front of the holddown screw under the receiver to float the barrel up just a bit; that may remove any interference from the folding foreend.
