11.75" or 12.5" Which barrel should i get for my new SBR? 5.56mm or 6.8mm SPC?

I am often asked what is the difference between the 10.5", 11.75" and the 12.5" barrels when I am preparing an NFA trust.

Murderman, DevL, Myself did some testing at the Impact Zone a couple of weeks ago. Murderman finally compiled the results and posted them on ARFCOM.

Murderman on ARFCOM was kind enough to post this. I thought some of the guys over here woudl find it interesting.

Two other long time arfcomer's and I spent most of last Sunday chrono'ing various SBR combinations. The data is presented below. It is safe to say that we all wish we could have run the additional 10 strings to complete the tables, but the heat/humidity was pretty rough, and time simply ran out.
