168 Grain A Max?
 

Does anyone have subsonic load data for the 168 Grain A Max? I have some 190 Grain bullets on order but i picked these up locally and I was going to start at 10 grains of 2400. Any info would be appreciated.

I haven't shot the 168's subsonic but a 240 SMK is subsonic in my 10.5" Novesky barrel with 8.5gr of 2400. Hornady's reloading manual shows a 168gr bullet going 1300 with 11.4gr of 2400.

11.4gr is probably a good place to start. With subs, always start supersonic and work down so you don't get bullets stuck in the barrel.

I am starting to work up loads for subsonic 168s.

I have been running 175 BTHPs at 9 grains of H110 with an OAL of 2.14".

My throat is short and the bullets are pulled milsurp so the ogives are all over the place which is why the shorter OAL.

I get around 1000 fps out of my 10.5" barrel.

I loaded up some 168s last week with 8.5 grains of H110 and they seemed to stay subsonic and had decent accuracy.

I couldn't get velocity readings on them so I will next time.

They cycled my rifle which has a pistol length gas system and the adjustable block was full open.

Thanks for the info, I should be able to try some loads this week. I really need a chronograph, but there allways more toys than money:smile:
