I think we need a little clarification; Shorts don’t necessarily shoot slower velocity than Long Rifle. CCI Quiet has the same velocity (710 FPS) as CCI CB Long. CCI 22 Short HP is a 27 Grain CPHP that is listed at 1105 FPS and are not overly quiet. I have however successfully fired the latter into my basement duct seal and plywood trap without any pass-through.
By the way, the CB Long from CCI is a 29 Grain bullet, I don’t recall what the quiets weigh. My old 1935 Western Field/Mossberg 42 has a Shorts adaptor for the magazine consisting of a screw and feeding has been flawless.
Yes, shorts arent lower velocity than LR, but lighter bullet more than anything.
Quiets have the same 40 gr bullet as a LR (as mentioned above), but at lower velocity, like CBs, to reduce noise. The heavier bullet WILL shoot through more backstop material than CBs. Id not choose quiets for indoor shooting, but as outdoor pest loads.
I think much of the problem with shorts and chamber issues was the lead or powder/carbon ring that was left uncleaned and corroded under the lead or carbon fouling. Just average cleaning of running a brush a couple times through the bore wouldnt really clean the chamber that well. I think many people probably never
really cleaned the chambers well after shooting shorts. Shooting LRs in the short fouled chamber may have exacerbated the problem, making it harder to clean the chamber well. I shot quite a bit of shorts when a kid in the 70s, that was well into the non-corrosive era, and there were not any leftover corrosive primed shells on store shelves for the unwary to buy or use inadvertently. Many guns would manually feed shorts, like Ruger auto pistols or 10-22, but wouldnt cycle the action from the lower recoil. When CCI CBs became more common in the 80s, I liked them for squirrel hunting during deer season. Wed take our 22s with CBs for the slack times in the day when deer werent active, then switch back in the afternoon when the deer started being active again. They were also good later when living in the rockies and my dogs were a bit gunshy, I could shoot grouse or squirrels and not spook the dogs, even from pistols. They were also great for shooting mice and pack rats indoors in a cabin I used to live in, and in the tipi.
Quiets are OK, but not a direct replacement for CBs for indoor or areas where the added penetration may be a hazard.
