Clogging has been a known problem for years with JHP's. Lot's of new tech out there nowadays in regards to bullets. I like the XTP's for the wife but I have recently (in the last year or so) been introduced to the Lehigh Defense manufacturer. Mainly in their MLer bullets but I did get some of their Xtreme Penetrator for my .458 SOCOM for hogs. Excellent performance. Good enough that I am going to get some of their pistol bullets for one of my .45ACP's, probably the old trusty colt since she aint to picky about bullets but sassy about powders, and do some testing.
Namely these
And these
Those last ones are the same design as I got for the SOCOM just littler
