@Dr RayI’ve never had issues with “old fashioned” bullets.
We've never had problems with old fashioned bullets because we are just old school and old fashioned.
We learnt what worked and didn't and use what worked. We didn't shoot into the next country for a shot at game.
We kept ranges reasonable and put the bullet where it was meant to go.
Yeah that's right we went HUNTING not shooting. We still had stuff ups but it was usually OUR fault with bullet placement and impatientance,Not waiting for the right shot. The bullet usually did its job if we did ours.
