Have you contacted Aguila customer service?
BTW, how long do they measure?
I don't have an accurate way to measure them, and I may have jumped to a conclusion that it was OAL because I put them back into their plastic carrier and ran a course file over the tips to knock a little off and these all fed fine, so the obvious conclusion was OAL. But it may be a complicated interaction of OAL, rim thickness and diameter, bullet ogive that have them not stacking in the magazine correctly, If I recall if I loaded 5 rounds or fewer they all fed.
I don't see any reason to contact Aguila, first it was purchased about five years ago, and it is well known that not all .22lr ammo works well in all .22lr guns, and I've no way to claim it is out of SAMMI specs. As I said it works fine in many of my other guns, just not the two pistols we shoot most often.
I certainly won't hesitate to buy more if the price is right, but it won't be the basis of my stocking up for the next shortage. The only ammo I won't buy at any price is Remmington Thunderbolt, not for accuracy or duds but because if causes horrible leading in too many of my pistols since they changed from the old (circa 20003) waxy lube to a dry "polymer" coating. It used to be my mainstay as Academy sold it for like $7-8 per 500 round brick back then. As I say to the people who won't buy Wold/Tula steel case "good, more for me" so I leave the Thunderbolt to people who don't seem to have an issue with it, but if a brick lasts you a year, it may take a while to notice the problem, we typically run 400-500 rounds per outing shooting steel plates, rate of fire may be a factor too.
