I wonder if all of the brands would do a recall for squib rounds? At least Sig is doing the recall and putting out the information.
I'm pretty sure the major brands would - there's a lot that depends on their reputation. I DO remember seeing occasional recalls from the big boys over the years.
Smaller "boutique" ammo makers I'm not so sure about - I've read some less than confidence inspiring anecdotes about CorBon and Buffalo Bore. So for what is euphemistically called "serious social work" I stick to premium lines of ammo from the major brands - and still keep my fingers crossed.
