Has anybody here ever used these? I came upon them in the new Cabela's catalog and they chamber them in .221 Fireball so I am real interested since there is a real shortage of variety of factory loads for this caliber. (There is currently 1 and Nosler is designing another one now but I don't think it has been released yet) I could not find any good Calhoun websites that show expansion or ballistics. Also what is a double hollow point? Does it have a hollow point front with a hollowpoint boattail or what? Thanks in advance for any info. I posted this in the Caliber Corner and did not get too many responses so I thought I would try it here. Basically I am looking for coyote/varmit/target bullets.
