Before muzzleloaders got all high-tech in the 90's, patched round balls worked great for me. I used them almost exclusively until I bought a muzzleloading barrel for one of my Handi-Rifles. I never lost a deer due to ball failure. I deeply grazed a couple as a result of hangfires though. I was thinking how round balls have probably taken more game than any other style bullet because they were in use for over five centuries.

I still use them in my 58 caliber caplock Hawken.
