On pepper poppers it is always important that they are made of the right steel. Secondly, the upright angle of the pepper popper is always a consideration. Col. Jeff Cooper himself [ met him in the early days of Combat shooting and IPSEC, yes I am that old] always lectured on these very important considerations. There are safe steel targets and then there are unsafe ones. I use flat nosed 230 grains on them. A safer bullet design for steel. Hornady continues to make them. ............ best regards, and practice when you can my friend.
