Oh am I peeved.I bought two Butler Creek Banana Magazines with the steel lips. Right on the bag it says: "No Fail Feed Lips".
I tried it out today on my new 10/22. Every second shot jammed. I mean EVERY second shot jammed. No matter if I put slight pressure forward, rearward, or downward...it still jammed.
The gunstore I bought them from is 3 hours away, can`t really return them easily enough. I have absolutely no issues with the factory 10 shot mag. I could shove these up someone`s _ _ _!!!
 
Try loading 5 to 10 rounds at a time to see if it feeds better with less spring pressure. Fully load the mag and leave it loaded over nite or for a few days. They usually function after a bit of a break in period and the spring tension finds it sweet spot. If that doesn't work then return it. Good luck...
 
Mine did that too (both of them!!)

Today, using Blazer 525 bulk... I ran through 25 rounds in each, multiple times, with ZERO issues!!

I did spray a bit of that 'dry lube' once, but really, I didn't do anything. I got bent rounds and stuff, but just keep going and it seems to fix itself.

I was peeved too, but keep trying!!! Putting two of them together and ripped 50 22LRs was pretty darn fun...

Don't give up yet...

Wow, thanks guys!!! Patience is something I wasn`t born with. I`ll try and sort these out. Maybe someone will come along and buy the whole she-bang and I won`t have to deal with breaking them in! Oh well, in the mean time....I`ll keep trying. Thanks,Darcy
 
You haven't mentioned what kind of "new" rifle (Ruger of some breed) you were cycling these rounds through, or if you tried different types of ammo and/or magazines.


My suggestion would be to first try the same ammo in a different magazine if you have one handy. The stock 10 rounder mag makes for a good benchmark test. You could also try a different brand of ammunition in the same BC mags and see if the problem persists. Same treatment for the second magazine if you haven't tried that one yet. If the jams persist despite the different ammo and different mags, you may have an issue with the rifle itself.

I have never had any issues with any of the several Butler Creek magazines I have owned personally, or heard of issues from friends with the same magazines, which is why I suggest a bit more troubleshooting! My Ruger doesn't like to eat that cheap Blazer ammo, for example. The waxy crap they coat them with jams up my business like crazy. I've had the best luck so far with Remington Thunderbolt; might be worth a shot! ...pun intended.
 
Ruger 10/22. I know the factory 10 shot will eat anything I put through it. As for these 25`s, I had just tried the one. I couldn`t take it anymore....switched to my old rimfires I enjoy more. I`ll have to try one certain brand through these mags and see.
 
Man BC needs to either adjust their tooling or put instructions on the bag. First, you need to file the top of the feed lip header and the left hand corner edge (opposite side of where the rds feed) to clear the bolt. Otherwise it will bind up the bolt slowing it down enough to cause a lot of ftfs. Next, you need to load them to full capacity and let them sit for a day or two to set the spring. Do this and they'll feed great but they all need it. "Never fail" means they won't wear out like plastic feed lips. Also, don't put any oil in them. They're made with self lubricating polymers and will last longer dry. Oil will attract powder fouling and make them gum up sooner then they'll be harder to clean. They're great mags but they need just a little work first. Then they rock.

I need pics lol. The feed lip header...this is the tall one of the two? If so, how much does a guy file????What would be the left hand corner edge? Are you talking the taller metal feed lip where the "rim" would be???
Here you go, the culprit itself.

I too bought my 10/22 and two steel lip butler 25s all brand new .
At first I had EXACTLY the same thing you are reporting . After about 400 rounds the problems went away .
Now , at 5000 ++ it works every time unless the round is a dud .
Keep shooting it , I bet the problem will disappear like mine did .
I remember thinking I had gotten a crappy 10/22 at the time . Don't sweat it though , until after 500 or so .
Cheers
 
I have a steel lipped Butler Creek mag and a plastic Shooter's Ridge. The BC mag in this case has been fine, but you can see a little bit of wear on the back end of the lip, from the bolt. That corresponds to the same area I had to do alot of sanding on the SR plastic mag to get it to work...though in that case it was like the entire lip assembly was set too high, hence the visible sanding marks across the entire rear of the green plastic lips. It's been a while since I did it, but I think the symptom was that the bolt wouldn't close at all with the mag inserted. Both work reliably now.

You want a bad jam, see what happens when your mag loader gets an empty case mixed in and you load that 20 rounds deep into one of these things... f:P:2:

I filed that corner so it is more beveled(round). It seems better, but when a shell is being pushed forward into the barrel, its like the rim is digging into the lead of the shell below it. This makes me think that it is the spring pushing too hard upwards. They had been fully loaded for about 2 days before I had tried them. I`m just going to have to wait for them to wear in, like others have said.

Dagmaar and I had the exact same experience. Just keep shooting. Yesterday I had fantastic luck with the Blazers. Try different ammo but that's just an excuse to put rounds through it!!

I own about 10 of these mags now, I find that I usually have to run about 3-8 times through each mag before they really start working smoothly.

Here is a really useful tip.

Before shooting the mag, use a black sharpie and cover all of the metal feed lips and areas that can get touched by the bolt. Run through a bunch of mags, and when you are done, the marker should have worn off in the areas that need a bit of filing. Works every time.

I thought of that last night. I need to take the old Cooey 67 out this afternnon....its been at the door begging me. The Ruger might as well come along also.
 
First thing I do when I get new mags for any of my guns is load them up and put them away for a week or two. Helps to loosen up the springs a bit. That being said I don't know if it helped avoid feeding problems but I have never had any issues like you are describing. I have 4 BC SL 25 rounders and I have never had a problem with them. Rarely clean them either. Good luck with that!
 
The 2 butler creeks I have needed the ramp adjusted a little. What I do is lock the bolt back and look at the alignment of the cartridge and the chamber. With very very very light dremeling usually you can fix any 10/22 mag (even promag)
 
Well I ended up filing and rounding off the corner on both. Now they work pretty darn good now! Now that I look at the factory 10 shot, it is rounded from the factory.
