Hi, I recently saw a comparison test and it shows how great the challenger 12 gauge slugs are at penetration. Decided that ill probably pick myself up a box. What I found Canadian tire was charging is $28 in one location and $31 in another both for the 10 round packs. Seems quite steep to me. Is this the going rate? Going to check my LGS soon before I give Canadian tire some money. Looking for what you folks are paying.
