I was at the local gun shop last nite & over heard a conversation about repairs being done.
it seems they had a few 22 rifles come in that would not hit anything. the common denominator was the low power Aguila 22 sub sonic ammo.
the one gun had 5 rounds stuck in the barrel 3 " from the muzzle. another gun had 3 rounds stuck about 2" from the muzzle.
because these rounds are soft lead they were able to drive the rounds out of the barrel.
they also tested a brand new box of this ammo & the rounds stuck again
I own and shot thousands of rounds of Aguila subsonic ammo with my suppressor. I've never had an issue with Aguila ammo. Not sure of what moron was shooting a firearm and didn't notice more than one squib.
Aguila subsonic was/is more accurate than the CCI subsonic and other subsonic ammo that I had...I sold the rest and kept the Aguila subsonic.
All the Aguila is in that color of box. The subsonic (that I'm familiar with) is like an extra long lead bullet loaded into a .22 short case. The powderless is a regular long rifle case with a normal size but pointed bullet.
I have never had a problem with shooting the low powered rounds out of a clean barrel. My guess would be that many people rarely if ever give the attention to cleaning the ol"22" that it deserves. That may be the culprit when bullets don't make it out of the barrel.
