Great response,I put failure in quotes hoping to imply sarcasm as so many folks are split on copper vs cup/core. I also felt the good performance of the hammer on the second pig with much poorer shot placement (in the bum) would add the the irony, but text doesn’t translate like true speech. I try to never give a product negative reviews unless totally warranted. I prefer honest experiences based on a given occurrence and everyone can choose for their own. Thanks for your input and I’ll try to keep my words more clear in the future. To be fair to the Mfg (Hammerbullets), I am fixing to order more!
