No. Start again with cast bullets. Or cup and core only, but just bullets that can be driven to 2800 fps or more safely from a 22 inch, gold plated barrel.
They have to group 0.5 an inch or less at 100 yd., and double in size when they mushroom. Naturally, they must retain over 95% of their original weight.
Shot offhand, at a running target, wearing camo pants, at night, from a moving truck.
For the campfire, this is probably done regularly.
