Motor1's avatar shows a good sized, well appointed rig for deer, varmints, and such.
Short barrels (16" and under) do not allow the bullet to accelerate to higher speed of the 20" bbl because of limited internal ballistics. If you are hunting feral hogs, ground hogs, heavy brush game, and the like, 16" is probably sufficient.
[ETA] Practically all of Hodgdon's tabulated muzzle velocities for rifles are based on 24" test barrels.
Everything on mine is stock. 16" barrel, all original parts. I'll admit, I just hopped on the AR bandwagon last month. Trying to find parts right now, well, you all know....lol I'd certainly like to do some upgrading but right now it's mags, optic and all the ammo I can get.
Anyway, back to the topic, I'll be hunting Michigan Whitetail. The deer we usually harvest aren't the biggest so I don't need a load to take down a mule. But I want to be sure that I'm packin enough power with what I have right now.
Ive taken whitetail with the rifle in my avatar. It is 1 in 9 22" .223 I highly recommend the Sierra 65gr Game King, It performed great every time. I would still avoid heavy bone like front shoulders. I did notice too that there is now a 55gr Sierra Game King and it is getting very good reviews from deer and hog hunters. Personally I will stay with the 65gr. I load mine with Reloder 15 but since you only have 16 inches of barrel you may want to experiment to see what you can get out of it velocity wise. RL-15 may not be the best choice for the shorter barrel.
