I see you did very good with the 200 gr.You probably noticed that some of the petals break off the sabot,As I undersatnd they are made too.It has never hurt my accuracy by doing so.
They sure work on deer too.
Hornady made some .452 sst in 200 gr,that I would love to try,but when I called them a lady said that they hadn't decided how they were going to market them,That was several months ago.So far still haven't seen any either.
Good shooting.
