I accidentally purchased 11 cans of .45 caliber GOEX Pinnacle Pellets at an auction. Would it be safe to use these in a .50 caliber inline?

I haven't opened any of the containers to measure the length and diameter of the pellets. There's 100 pellets per container and the container is marked with weight a little over 10 ounces. So I'm assuming each pellet will be +/-44 grains each.

What can I use these for???
