близък е и ще върши работа. малко по бърз е
-1gr по малко ще му слагаш от N135
Ако е 26gr за 55gr с N135 то тогава 25gr ще е с N133

====
At that length you definitely don't have enough bullet in the case. In two different popular name AR's 
for Hornady 55 FMJ's to touch the lands one had an oal at 2.370" and the other was 2.390" overall length. 
Now in my one bolt action .223 Rem to touch the lands the overall length was 2.246". 
Seat them to recommended lengths from 2.200" to 2.230" and you're most likely to not notice any accuracy improvements 
trying to seat longer especially in AR's.
