RE: What kind of bullet do you shoot?
Used to handload Hornadys, but without a press set up, I'm using 130 gr. Nosler ballistic tips. I like the old Nosler partition bullets, but for a sometimes small East Texas whitetail they penetrate too much.
Regardless of the caliber, for a deer to take one in the boiler room and keep eating is probably just an example of weird but true hunting stories. I assure you, that a .270 will usually kill deer effectively (grin).
