The extra shots cost an infinite amount less than the regret of not shooting them. I learned that lesson 1 time and it still haunts meI've killed a big bull moose with a CVA Wolf, two pellets of Triple Se7en and a 250gr Hornady SST. It just stood there, so I reloaded and hit him two more times until it tipped. The moose went a couple steps after the first hit and took the other two shots just dying standing up. That first shot was 100% a kill shot, but why risk it?
