The GameKings by Sierra are great animal getters. I know with this next comment I am going to open a huge bucket of "My buddy this, my dad that, I did this" so here we go.
Just be careful to not get any loaded with MATCHKINGS. They DO NOT OPEN. They are designed to be used on paper and sniper work. The are designed to group very tight, stay streamlined and consistant. That is what we shoot in my agency for sniper work and what I have used for benchrest comp and IHMSA work.
I have traded over to Ballistic Tips and have great success with this load on hogs and 'yotes.
