Make your own.
I've been reaming out 300gr JHP's to about 255gr for the last few years for groundhog. Just a couple weeks ago I've been attempting to form a rubbery point to partially fill in the cavity some to add to the BC of the slug instead of being a flying ashtray.
Right now, I've settled on using hotglue to use as the tip. Working on making a mold for them now. Once the mold is complete, I'd use the gluegun to fill the mold - then once cooled, open it up and just push the tip into the nose of the bullets. I'm gonna guestimate that the point would help expand my ashtrays for more red-mist effect.
