M1A load

[devster55]

The US Military Mk316 load, which is the load for 1000 yds, is 175 gr bullet with 41.7 gr of IMR4064, loaded to 2.81+". So, as was mentioned, 41.5 with a 168 gr bullet will be fine. Load to about 2.815". The Mk316 load is probably a little hotter than it needs to be for most shooting.
