I'll 3rd it! Been using the 53gr Vmax in my 223, 223AI, and now 22-250 since they very first were introduced, shot a lot of 52gr Amax before that, and they've both been not only exceptional shooting bullets for me but they are my favorite coyote bullet in those cartridges as well.
I'd imagine those Hornady 53gr BTHP's would likely shoot well and if they shoot close to the same as the 52/53 gr SMK's then they'd certainly be a winner in the accuracy department because those little SMK's just flat always shoot. My only concern would be lack of expansion but maybe you could trim the meplat on them creating a little larger hole and that could possibly help them open up more consistently. If you're just punching paper or bangin steel then it really wouldn't matter though.
