Just some basic information about 10/22 magazines ..... The normal 10 round factory magazine is rotary fed with an adjustable tension rotor spring. All highcap 10/22 magazines to include Ruger BX-25s are "in-line" feed with fixed "ribbon" type tension springs. Before any magazine will feed properly, spring tension on the round being fed (top round) must be within limits. If spring tension is too tight, the bolt will have problems stripping the cartridge out of the feed lips. If tension is too light, the top cartridge won't seat properly in the action. Either condition (too heavy or too light spring tension) will cause feeding problems.
With factory 10 round rotary magazines, spring tension is adjustable. As long as the first round isn't too tight and the last round isn't too loose, the magazine will normally feed flawless. In-line magazines (all brands) do not have adjustable tension feed springs so you may get one magazine that is too tight and another that is too loose. The concept is simple ... the magazine spring has to have enough tension to push the rim of the case up and into the breach face pocket without binding the bolt.
There are several compounding problems with in-line magazines that can cause feeding problems ... the first being the magazine follower. Factory 10 round magazines use a rotary device and do not have a follower. In-line magazines all have a follower that can bind in the magazine body. The most common malfunction with highcaps is .... the follower gets stuck in the body, which reduces spring tension on the top round that is trying to feed. Without proper spring tension, cartridges rim will not seat in the the breach face "pocket" and the nose of the bullet will point down slightly, which will cause a misfeed. So, if there are any burrs inside the magazine body or the contact area of the magazine follower, feeding will stall when the follower binds. Built up powder residue will do the same thing. If you buy a highcap magazine that can be completely taken apart, you can clean and remove burrs on the follower and body, which will eliminate most feeding problems.
As mentioned above, ammo can also be a contributing factor with any magazine. Some bulk grade 22s suffer from what I call the "pop-bang syndrome" (especially Remington bulk pack). When you shoot, most rounds make a normal BANG when fired but some rounds make more of a POP sound. When you experience something less than a full report, it means the powder charge was light. These light powder charge cartridges may not develop enough energy to blow the bolt all the way back. Of course if the bolt doesn't move all the way back, it may not be able to strip the next round from the magazine. Factory 10 round magazines with a rotor are not fussy about bullet design because the cartridge is contained in a dedicated "slot" in the rotor. With all in-line magazines, the bullet nose can drag on the magazine body and bind ... more common with hollow points.
Last is the gun itself. Because rotary 10 round magazines are way more forgiving, you may find your gun feeds perfectly with them, even if there are minor issues with the gun. The first significant issue is the extractor, which is the leading cause of malfunctions in all 10/22s. The only time an extractor actually extracts a chambered case is when you manually operate the bolt handle. When a round is fired, the extractor doesn't extract the spent case, rather the case is actually blown back from pressure inside the chamber. The extractor's job is to hold the case rim tight against the breach face until the case head strikes the ejector and flings it out of the receiver. If you experience a malfunction where a spent case remains in the receiver, the extractor is usually the cause. It is very common to get a factory new extractor that is not shaped properly. Three issues .... the first being the above where the extractor lets go before the case rim strikes the ejector, resulting in stovepipes. The second is where the extractor is shaped wrong and won't let the case rim slide into the breach face pocket. Even a rough breach face will impede feeding. Last is the seating depth of the magazine. If the magazine seats too deep, its lips will contact the spent case and cause the case rim to break loose from the extractor. Yes, there is a slight variation from gun-to-gun and from magazine to magazine so it's not unusual to have a magazine that works perfect in one gun and nothing but malfunctions in another. An aftermarket extractor (I prefer Volquartsen "Exact Edge") is a great $15 investment that helps eliminate feeding and ejection problems with all magazines
When you use a highcap magazine, any slight imperfection in the gun may cause feeding or ejection problems that don't show up with a standard 10 round rotary magazine. Trouble shooting is simple ... if your 10/22 feeds and ejects properly with one highcap magazine and not another, it's obviously not the gun. If your 10/22 doesn't feed or eject properly with highcap magazines but works well with the standard 10 rounder, you have an issue with the extractor, breach face, or magazine seating depth. If your 10/22 has feeding problems with 10 rounders, I can almost guarantee it will malfunction with highcaps too.
So in summary ... it's really a crap shoot when using any brand of highcap magazines. The absolute best highcaps for 10/22s are TI-25s, see:
TI25™ ADVANCED COMPOSITE ADJUSTABLE STEEL LIP MAGAZINE FOR These magazines are fully adjustable for seating depth, can be totally disassembled for cleaning or deburring, and have steel lips. Of course they cost more than BX-25s (about $40 each) but I have found them to work exceptionally well in all three of my 10/22s. I only own one BX-25 and it is "fussy" (follower binds up) in all my 10/22s. I don't think I have ever fired a full magazine without at least one malfunction. I bought a new 10/22-TD recently and the BX-25 wouldn't even seat. I had to file off both edges of the stock's magazine channel. Proof that variations that affect function.
