In case nobody mentioned it, I personally have had better terminal performance out of the flat base Hornady 100 grainer than the BTSP 100 grainer�.
YMMV
Not so much terminal performance, but it is scary accurate in my rifle. I averaged groups in the .6s with that bullet....until they quit making them.
Like the 170 grain FP for my .30-30.....geeeezzzz, I think Hornady took inventory at my house and said "Let's discontinue these"...
