I got this via email this morning from HEVI-Shot....figured I needed to pass it along:

URGENT ANNOUNCEMENT FROM HEVI-Shot
At temperatures below freezing, our 12-gauge, 3-inch HEVI-Metal® and HEVI-Steel® shotshell wads may crack on ignition. This may cause a “squib load”, with an off sound and reduced power.
While this squib load will not damage your gun in any way, it can result in a wad stuck in your barrel, because the force of some of these shells may not be strong enough to push the wad all the way out of the muzzle.
The danger comes if you fire again without clearing a stuck wad from your barrel. This can cause barrel damage or injury. If you hear an off sound with no power, please stop shooting! First, unload your gun – and then check your barrel for obstructions before you fire again!
Please do not shoot these shotshells. Instead, please contact us for replacement shells. We have fixed this problem in current production.
After we were contacted about squib loads, we began an intensive investigation that led to an understanding of the problem by the evening of 19 November. We want to get this notice out to our customers immediately. Please share it with your hunting friends.
The wads we bought between July and mid-November used a low-density polyethylene plastic. We switched yesterday to a linear low density polyethylene, which performs safely in all weather, including very cold weather. To understand the difference, please go to:

this explains a lot - last 2 guys I hunted with in cold weather used hevi-metal shells and we just chalked it up to poor marksmanship, but they were ineffective.

probably 100 guys that could say different, but i used more shells on clean up shots for them than usual

Ha! 30$ for 10 shells and they can't design a wad to work under freezing temps?

Junk.

they are still very expensive/top end shells - to only have pellets bounce off of or not even reach the birds.

Definitely way too expensive for that shit to be happening. I get that mistakes will be made but for 30 bucks a box....come on now

Didnt Remington Hyper Sonics have the same issue a few years back too?

i think the Remingtons were blowing the shot cup (wad) apart or was that winchesters?

Got lucky my case was lot code 401410. In all the for years I've shot them, they have been great. I know this shit happens, but atleast they are doing there part in making it right. Really sucks is during season

My case falls in the recall. Been shooting the hevi steel and haven't had a problem but of course this is setx so not many freezing days.

Yea, apparently it's only in extreme cold weather that their having issues.....but you never know. They're offering to replace them, probably worth it just for the peace of mind.

Ah shit, I'm about 4 boxes into a case now, gonna have to check the lot #. I swear I'm not much on blaming anything but myself for a missed bird but there were a few shots I know damn well should've went down lol!!! Gonna check this out. Thanks for the post

Royboy10 how you liking the Hevi steels? Minus this little incident
