I've had two recovered bullets, from previous successful hunts, that are in good enough shape to Reload and reuse on two hunts again this year. A 405 grain hardcast .458, originally used in a 1874 Shiloh Sharps to harvest an Elk way North in Saskatchewan. I Reloaded it and used a 1885 Winchester High wall breech loading rifle and harvested a nice Elk with it.
The second was a .454 Casull, 300 grain bullet that took a 400lb hog. Reloaded it and harvested another large hog with an open sighted .454. I am amazed that it all came together, and during my 12 days on the road, traveling 6400 miles, I actually succeeded in cleanly and humanly harvesting two critters, filled both my freezers, had a fantastic time, and created an awesome story to tell. 4 hunts, from 15 years apart, using two bullets to take 4 animals.
