Yes, I've done testing with the penta point hp's (5 sided hp's) & the standard round hp. Both are very affective hp designs. It depends on what bbl/speed of the bullets being shot as to what ratio of alloy (pure lead, 40 to 1 lead/tin, 30 to 1, 20 to 1, ect) I use for the best expansion.
The "cookie cutter" huge hp's are my version of a jacketed hbwc. They are made out of old 9mm cases that I find laying around at the range. The jacketed segmented hp's are the same thing, old 9mm cases. I also cast my own lead hbwc bullets & they can be very affective when they're turned around to make a huge hp.
Some cast lead hbwc's along with some segmented hp's and the jacketed hbwc's for the 38spl/357.
I also cast a Keith style swc bullet for the 44spl/mag, a H&G 503 clone to be exact. I cast the penta point hp's, large round hp's & the small round hp's with this bullet. I also cast my own lead hbwc bullet for the 44spl/mag & make a jacketed hbwc version "cookie cutter" of the same bullet out of old 40s&w cases for the 44spl/mag. And I also make a jacketed segmented hp bullet out of the old 40s&w cases.

Any of these bullets can be extremely affective when they are tailor made for a specific speed that a barrel length will produce. Anyone who shoots/tests hp bullets will find that there is a sweet spot where that bullet will fully open & retain a high percentage of its weight. A bullet that performs well in a p+ load in a 38spl/6" bbl combo will not do very well in a 2" snub nosed revolver. And a lead bullet that fully opens & retains most of its weight @ 750fps will have a hard time in the 1000+fps range due to the bullet breaking up too quickly.
Testing is everything with hp bullets & sometimes the hotter loads are actually poorer performers than a slower version of the same bullet.
