I have developed a load for my 10.5" 1 in 8 twist AR barrel with 2400 that is subsonic with Sierra 220 gr Matchkings (7.5 grains) and is reliable in function and relatively quiet (sounds like an airgun).
I just got a scope yesterday and have not yet tried this load out for accuracy.
Is the Vihtavuori worth the cost in regards to accuracy out of an AR in 300 Fireball?
Also since 2400 is faster burning, is there a significant sound difference with the slower burning n110?
I'm curious since the Sierra manual recommends it for most loads as the most accurate (though the velocities were far from where mine are with the 2400).
