High Speed Alloy Pellets are LOUD

I shot five. They were so loud I thought people would call the cops. I think I shot a total of about a hundred rounds tonight. The Crossman Alloy pellets sounded like gunshots. Oddly the gun itself was quiet, the noise was further out, like ten feet or more out from the gun.

Sounds like your pellets are going super sonic. Experts here on the GTA claim anything over 950 fps won't be accurate. Assuming this a spring piston rifle light pellets can be damaging to the rifles internals.

Yep, you were hearing a sonic crack. Alloy or any too light pellet, are damaging to spring powered air rifles.

As Kailua noted, you're hearing the sonic crack of your pellets break the sound barrier.
And, as KYMike notes, you are damaging your spring gun by shooting those junk pellets because they don't have enough resistance moving down the barrel to cushion the piston for your compression chamber.
You're wrecking your seals, spring and compression chamber itself, the last of which cannot be replaced without scrapping the gun and getting a new one.
Go back to lead, and forsake the alloy pellets as the gimmick that the likes of Gamo put out to create bogus numbers for muzzle velocity.

If you live/shoot in an area where lead is banned, or you just want to use lead free for safety concerns you might want to look at the Dynamic pellets from Airguns of Arizona. They're well made, not quite as light as most alloy, accurate in some guns/barrels but they are pricey. I would stay away from the lead free Crosman/Gamo junk....

ya those pellets ive seen damage piston seals in 5 shots.. so id stop using them unless its out of a co2 gun or a pcp but even then they are inaccurate... altho out of a co2 pistol they actually do decently.. my walther ppq co2 pistol shot very well with them

Oh, no worries. I was just going through my pellet selection box trying various pellets. I'd put up a target with five lines of targets and shoot a different pellet type for each line to compare. Daisy pellets are about as loose as Gamo pellets. I shot four shots with the alloy (one line on my target) and halfway expected car alarms from the noise. I hope I didn't hurt anything. It shot fine afterwards, I went on to shoot a 182/200 ten yard match score. I generally shoot 7 or 8 grain pellets out my Whisper. It loves RWS Superdomes and I just found it also loves RWS Basic Match pellets. They are both on the loose side but not nearly as loose as Gamo and Daisy. It shoots decently with CPHP but they are tight, loose and all over the place and Kodiak Coppers which are on the tight side. It shot decently with Crosman Pointed Hunters and pretty well with Crosman Destroyers both loose with quite a lot of variability although neither were very impressive.
If you shoot one pellet of a given brand/type and it's tight and then another from the same batch is loose, your not going to get any sort of real accuracy. RWS and Beeman both seem very consistent.

I found them to be inaccurate - trashed the tin I had after 8-9 shots.
