I have used Accurate 2460 and 2520 in the AR. Being a ball powder, it meters very consistently. I got good accuracy from it, but I burned out two AR barrels at about half expected life. As long as you don’t do rapid fire strings, and using mild to moderate loads, I expect 2700 would be fine. 

No, they were mid-range loads.  I believe the issue was a combination of the hotter burning propellant with strings of rapid fire.  We shoot two ten round strings in rapid fire in fairly quick succession as part of the 80 round Service Rifle course of fire. This occurs in both sitting and prone rapid fire stages, so 40 rounds in total at a match.  The rapid stages are 70 seconds in sitting and 60 seconds in prone. The barrel heats up pretty good. 

I thought the first time was an anomaly, but it happened again, at about the same total round count (1500 rounds). 

AA 2460 and 2520 are double based powders which have Nitroglycerin in the composition.  They also burn fairly dirty, which was another downside when shooting thru an AR. I stopped using this powder on Barrel No. 3 and it’s been great ever since. I changed my short range loads to H4895 and 600 yd load to N140 and have 3,000 rounds on barrel #3.  

I don’t know how much NG content there is in AA2700, but unless you’re doing strings of rapid fire, I don’t think you need to worry about it.
