The 12.5" 65G SBR is my favorite rifle right now. It's a great balance of weight, size and lethal capabilities.
People say the 300 Blackout is a great option for a personal defense weapon. It's quite effective in barrels as short as 8". I was wondering how something around that length would perform. Part of my hope was to only have two calibers for the AR-15 platform; Grendel and 556.
From the information published by Precision Firearms:
8.5 Bartlien 2100 FPS 123 Match King
And info from the interwebs on the 110gr Barnes TSX
8" 300 Blackout 2051 FPS 110 Barnes
I'm sure there are a lot more variables that I'm not educated enough to ask about, but I'll try and learn and keep the discussion moving. Thanks for the input, apologies for the ignorance.
For instance, I'm sure the 129 ABLR would be much more effective in an even shorter barrel. Unfortunately I don't reload.
