Since I have a little time on my hands I was looking as some of my "stuff" and noticed that my BX 25 mag for my Ruger 10/22 is about the same length as the 30 round mag for my AR, why? Seems like it would be a lot shorter since its a .22 LR. I will actually put a tape measure on it and see, it may just be the perspective that makes it seem close to the same.

Also sitting around thinking about cartridges I got to wondering why the 6.8 became the "go to" upgrade to the AR 15 Platform. Why go to the 6.8 instead of a .257 or even 6mm. Seems like the small cased of the .223/5.56 would do better with the smaller diameter bullet that a 6.8. still able to keep up the velocity and make a great medium game (deer) round. Is there a ".257 AR" type round? Playing around on my bench I sacrificed a few .223's to neck them up to .243, .257, .284, and even a .308. Gotta admit that the .257 one with a Nosler Ballistic Tip looks interesting. Just wondering.
