Up until the last few months it was very difficult to find 300 BLK ammo, but I saw 6.8 SPC everywhere, from common sources, PSA, Cabelas, Bass Pro, LGS. I think there are a lot of 300 BLK rifles out there, but not regularly shot. I probably see more 300 BLK at the outdoor range than 6.8 SPC.
I have 6.8 SPC and 300 BLK. 6.8 is mainly for hunting (deer and hogs). 300 BLK is for fun (SBR with suppressor). Yes, I could hunt with it, but 6.8 outshines it significantly.
I reload both, so ammo shortages haven't been an issue for me. I can shoot either. My 6.8 is a lot more accurate as well, 300 BLK does seem to load as consistently for me.
I like them both, but if you really look at the ballistics, the 6.8 SPC is a nice caliber on the AR15 platform.
Sheeze..... I almost hate commenting on these types of threads because invariably a fan boy gets their panties in a bunch. And somehow their man-hood is challenged when someone doesnt agree with THEIR choice in rifles
This topic seems to come up once or twice a week..........
The ABSOLUTE fact is..... all of the calibers mentioned on this thread have their place, and are all innovative
There are at least 2 armies in the middle east that are using the 6.8 (40k rifle contract with LWRC)
LWRC is reporting that the US Army is actually considering the 6.8 again
I believe the 300BLK is actually growing faster than the 6.8 these days, AND it has many, many advantages.....but... if I am
choosing one to hunt with, the 6.8 is a better choice for what I hunt and the distances I hunt
I reload for the 6.8 as well, and the ballistics are significantly better.
The bullet performance made the difference for me.
The Hornady 120g SST stays at 1k ft lbs out to 275 yards
The best hunting bullet I could find in the 300Blk drops below 1k ft lbs at 125 yards
If you hunt at less than 150 yards BOTH will do just fine..........
Good luck, and PLEASE DONT BE OFFENDED BY MY INTERNET OPINION.... they dont really matter....
