Seems like anytime the .223 Remington and deer hunting topics come together, fireworks begin. I'll only relate my limited experience with this topic. I matched a Youth Model Superlite .223 Handi with a small 4X scope a couple years ago. I wanted a short length of pull/low recoil rifle to use with kids who were particularly recoil sensitive. So far, none of the kids who've used the gun have managed to pull the trigger while hunting. However, before I began providing the gun to kids, I used it myself for that purpose. I loaded Barnes 53 gr. (all copper) bullets over 25 gr. of H4895. The load printed well in my (9" twist) rifle. I ultimately shot an average sized doe from 50 yards or so through heart/lungs. The performance (in terms of internal tissue destruction) was very impressive, though the round only managed to break the skin on the far side of the animal (i.e. no blood trail). Put another way, the "clockwork" of the deer was completely trashed. The deer did a tiny, circular dance and dropped dead. In my view, modern .224 projectiles intended for use on deer enable cartridges like the .223 Remington to perform well, so long as people respect their limitations. I don't think I'd be comfortable with quartering shots, but others may have a different view.
If I had it to do over again, I think I'd probably buy the standard weight barrel. The Superlite does fine for normal hunting purposes, but it certainly heats up in a HURRY on the range. Also, I think I'll probably bump up to the 62 gr. Barnes next time for a bit of added performance. As noted in some earlier posts, remember that while recoil is nil, the report of the tiny .223 Remington cartridge is BRUTAL! Make sure adequate hearing protection is available for shooters/mentors.
