Let me reword this. I'm wondering how many of you have gone the route of swapping of magazines to know they aren't causing an interference/inaccuracy issue, or found where one is?
Have any of you done any swapping of magazines to know they aren't causing an interference/inaccuracy issue, or found where one is?

I’ve had a similar issue as @Swells with a Brocock magazine. The issue occurred using .25 H&N Barracuda pellets. They fit loosely in the mag and the pellet’s nose affected cycling. Before I realized what the problem was I’d shaved the nose of a few of the domes when indexing the mag by forcing it to index without pushing the pellet’s nose back first. I figured out that the solution was to stick with JSBs (they sit more securely in the mag) so there was no need to purchase another mag at that point. Also encountered the issue with JSB King Heavies in an Edgun mag. The skirts were too wide for the mag. Using King Heavy Mk IIs remedied the issue, but I did notice that the issue was more pronounced in metal Mags as opposed to plastic ones. This is why I initially asked for specifics in regards to the OP’s question.

So the other night I saw listings for different diameter .22 pellets/slugs and it made me think how they line up in magazines. for thIf the design is such that they aren't held centered like a collet then it automatically creates a problem for all but the correct diameter ammo for that magazine. For plinker types this wouldn't be an issue but anything accuracy related would send shooters back to ss trays right off. It sounds like it's a common enough problem, for sure. All this doesn't even begin to take into account the inherent inaccuracies in manufacturing and needed tolerances in order for things to function.

I don't favor .22 air rifles and I hadn't noticed the varied diameters in .22 pellets until recently. I really don't know what the primary purpose of this variance is. As for holding pellets centered in a mag, I've seen some that incorporate an o-ring between a two-piece magazine design to compensate for space between the pellet and the inside wall of the magazine for a collet type of effect. Regarding accuracy, I'm convinced that pellets with bent and nicked skirts may account for some flyers that can throw off groups. I am of the opinion that jostling around in the tins during transport and dropped or beat-up tins account for bent/dented or nicked skirts. Consequently if damaged pellets aren't sorted out, they can contribute to inaccuracies. Airgunners who sort pellets have taken pics, reported, and posted slight variances (<0.5 grain) throughout their shipments.I think there should be some sort of reasonable expectation of slight variance in weight of mass produced projectiles.

I've found that even a poorly aligned magazine will push a pellet uninjured into barrel if the entry to barrel is slightly chamferred or polished.

Swapped magazines. 4 different BroCock and 2 different CARM in a BroCock Concept XR .177. Swapped magazines and ran the single shot tray in the sequence of testing as a baseline on how the magazines effected accuracy.
Absolutely a noticeable and repeatable degradation in accuracy using the magazines in this case. Each magazine produced it's own repeatable dispersion pattern, some worse than others, that was verified on many rounds of testing. We could even identify which pellets in the sequence were going to fly off and by approximately how much. This is what the magazine shelf and probe looked like after firing a couple magazines...covered in shaved lead.
I feel this is totally gun/manufacturer dependent. I've not had the same issues with an other brand I have.
