OK, new project and I need some advise. I am going to build a 300 whisper on an Ar15 platform. I am sick of carrying a levergun around on our hog doggin trips. Then when I get there they just blast my ears. The rifle is a DPMS it will be a 16" barrel and will be suppressed. I talked to Shawn Carlock as he now does most of my smithwork but, I cannot even remember what all we talked about on this project. Should I build it myself other than having the barrel threaded or the quick release for the suppressor? It seems that all the parts and even barrels are easily obtainable. Should I buy an upper like the Olympic Arms or something similar? Would it shoot decent? Should I send it to a smith and let them deal with it (slow way and I am a right now sort of person) Should I let SSK industries do it because they came up with it to start with? Now, the vast majority of my shots with this rifle will be point blank range. I am a little concerned with bullet performance on a hogs head at point blank range. Velocity will be in the 1000FPS range at impact. I am mostly concerned about riccochets and hitting the dogs. Also, even though the majority of the shots will be at point blank, I hate to limit myself to that. I might occassional shoot an exotic or something else. I will most likley be using the 220 or 240 SMK. Any thoughts on this bullets performance under 1000 FPS? Thanks for the advise! Oh and Shawn, feel free to chime in anytime.
