80% if my 45 ammo is FMJ and I'm happy with that for certain application like running a supressor but I'm looking to expand so to speak. I was comparing Federals EFMJ with Hydra-Shok and HST. What are their strengths and weaknesses? What I'm understanding is 45s have enough mass to expand reliably and still get good penetration. I'm not running a 45 that's picky about hollow points so I don't see a particular advantage to EFMJ apart from if my primary would go down beyound repair and I pick up a 45 that did prefer FMJs (though off hand I haven't heard of 45s ever being picky in that way). Also I hear there are certain locations that prohibit JHP so EFMJ is ok there. Of HS, HST and EFMJ which has the best wound characteristics and barrier penetration? Anyone with thier own favorite please chime in, I'm collecting opinions right now.
