In the LE .308 Loads sticky, it says the following down near the end of the thread:


Some of the the characteristics of an ideal performing general purpose rifle projectile are described here: https://www.m4carbine.net/showthread.php?t=22323 as well as in commentary by SSA Buford Boone of the FBI BRF:

-- Penetration of 12 to 18 inches
-- No impact AOA induced variations
-- Blind to barriers
-- No deviation from shot line after impact
-- Minimal fragmentation
-- Consistent terminal performance from 0 – 300 meters
-- Sufficient accuracy to hit threat targets out to 600 meters

The current .308 rifle loads that best meet these requirements when fired from a 16" barrel, include the Remington 150 gr Core-Lokt Ultra Bond, followed by the Speer 150 gr Gold Dot and Barnes 130 gr TSX.


My question is this: What rounds in other calibers fit this same description? Are there any 5.56 or 6.8 SPC loads that fit the above criteria? If not, what are the loads in these calibers that come closest to being considered "general purpose" according to the above description?

Pretty much all the barrier blind loads listed in the second paragraph of the 5.56 mm duty load thread (https://www.m4carbine.net/showthread.php?t=19881 and the recommended LE loads in the 6.8 mm ammunition thread (https://www.m4carbine.net/showthread.php?t=19884) will offer performance that meets the listed criteria.

Thank you very much, Doc.

My primary round to stock up on in 5.56 has been the T556TNB1. I know it's not as good in terms of terminal performance as the other four recommended 5.56 barrier blind loads, but it's cheaper, readily available, sealed around the neck and primer, has crimped primers, and matches the BDC on my ACOG.
