Non-related experience with jamming
Similar mistake happened to me in buying .22 LR ammo for my Smith Wesson M&P 15 22. I shot more than a thousand CCI, Geco without any problem. Winchester Wildcat give my jam once every 20 rounds. So I felt safe to jump on big sales. In a local gun store, I found a deal for Federal Ultra Target .22 LR 36 grain, with a plastic ammo can. Mostly for the copper coating over the lead bullet, and partly for the cute-looking ammo can, I bought a can of 2,600 rounds. First time I shot this Federal Ultra Target, it jammed my 15 22 once every 4 or 5 rounds. Obviously I could not "jam through" 2,600 rounds of this ammo. My life is too short for that. I complained bitterly on this forum.
Someone mentioned that 36 grain bullet may not give big enough recoil to operate the bolt reliably. Someone suggested that lubricating the bolt may help the jamming problem. It was true that I had been shooting my 15 22 dry, without any lubrication. So last weekend, I cleaned my 15 22, and for the first time, applied some Hoppe's 9 lubricant to the bolt and sliding rails. A pleasant surprise! Federal Ultra Target on my 15 22 only jammed once in about 20 rounds! The failure rate may be further reduced if I clean the 15 22 more frequently and apply lubricant to more places. Now I can see myself enjoy the plinking of these 2,600 rounds of ammo.
To be honest, that is not ideal. In the future, I will stick with CCI and Geco semi-auto (with bee wax). Non-stopping plinking through 15 22 is a big reward for my life. However, now I finally found a way to live through 2,600 rounds of Federal Ultra Target, and get some level of enjoyment out of it.
