6.8 SPC (4)
There is much contention about which round would/should replace 5.56 NATO. I doubt that anything will at this time due to our huge investment and general funding climate. If anyone does first I think that it will be MARSOC.
Anyway, if you follow the 6.8 debates on the internet you often hear that the 6.8 is a military-used or tested cartridge. Detractors usually say that it is not true and that there is no evidence that it was ever used despite that some of the folks stating first-hand knowledge are pretty credible. (Not to mention the comments from companies like Black Hills and Silver State Armory). But, as written proof I submit the following quote (and link and pdf) from folks that know a little something about M16/M4/AR15's:
LMT Press Release
The 6.8 has been used by Special Forces troops in Afghanistan with much success. As the obvious benefits of the 6.8 become more apparent, the US Army is taking the caliber under consideration to replace the 5.56 currently carried by US troops. The 6.8 has proven to be more accurate at longer ranges and have greater hitting power than the 5.56.
LMT should be known to anyone posting anything on an internet forum discussing the AR platform. If not, a quick Google should fix that. They are pretty well regarded :)
Yes, it is a little old (2006) but I am not arguing that it is going to be replacing the 5.56 just that it had been used/tested.

This looks like a good load for deer. The ballistic coefficient is about .40 which is better than my favorite load the SSA 110gr Sierra Pro. The only thing is that according to Hornady's charts (shown below) the drop in the 120gr SST and their 110gr VMAX @ 200 yards is the same.
Notice @ 500 yards (further than I would be hunting deer) the retained velocity is almost the same with the additional energy of a heavier bullet. Drop @ 500 yards is only a little over an 1" more. That's the BC.

I wonder how far off a 110gr caliberated BDC will be with it.
Definitely have to get my hands on some of the 120gr and try it out.
So, a lot of the "tactical" scopes come caliberated for a 223 BDC. Usually 55gr. Now you can use it with any caliber/weight but you will need to compensate for your compensator.
A couple of the scope companies will make a custom one for you that you can swap out. Much easier, especially if you have a favorite load. Leupold and Vortex come to mind.
I am considering an MK AR (1.5-4 or 3-9) and was curious how much it would. Not finding the price on the website I emailed them. The next day I received a price quote of $59.99 + tax. Not bad!
In case you were wondering it would be for a SSA (Silver State Armory) 6.8 SPC 110gr Sierra Pro SP load.
I am a huge 6.8 SPC fan. I made these for an avatar to use on 6.8forums.com, or maybe a t-shirt.
