    Accuracy International 308 using 178g Hornady A-Max reloads

    Somebody please help. I have been reloading 178g Hornady A-Max for use in my 24" Acuracy International 308 AW rifle.

    I have used 38, 39, 40 and 41gs of IMI 4895. I really cannot tell the difference at 200 yards. I want to move on to 400, 600 and finally 1000yards with these reloads.

    Speed with 38gs is average 2300 going up to +2600 with 41gs.

    Does anybody have experience or recommendations of powder weight with IMR 4895?

    Thanks

    A lot of guys use Hodgdon Varget, Reloader 15.

    I am using Varget. Though I haven't tried the 178 Amaxs yet.

    Hornady manuals are on the "safe" side. I always check Hodgdons online manual.

    I also load in .3 grain intervals.

    IMR 4895 and H4896 are relatively fast powders. I use H4895 with 155gr bullets in a 20" barrel with good results and plan on using the same powder with 178gr.

    That said, if I had a 24" barrel, I would be more likely to try Reloader 15 first.

    Many thanks.

    I did 300 yard today. Best group was 1" 1/8 and worst was 3" 1/8.

    Not to unhappy but want to be more consistent. Going to try the suggested RL-15

    One final question. With my file should I be going for the best velocity I can get?

    I tried the RL-15 and what a difference. Best I did was 7/8" group at 300 yards. Will keep experimenting with this powder.

    Thanks

    Not sure what you mean by your "file" - I assume it's a typo for rifle.

    The higher the velocity, the flatter the trajectory. But that does not equate to the best accuracy.

    The real trick to reloads is consistency. You want to find a load that gives you good consistent accuracy at 100yds (as a start). If you have a chronograph then look for a load that gives you a low SD/ES and where where small variations in charge will make a minimal difference in velocity. This is the so called sweet spot and will give you more consistent accuracy.

    You might also read Dan Newberry's OCW.

    A little bit of a different school of thought, depending on what your trying to do it might work better then other reloading methods.

    One of these days, I'm going to really take the time to wrap my head around the practical application of that concept. Particularly since it is not something that I appear to be able to do myself.

    I have read it, and I think I understand it, but I haven't really tried it.

    When I get some more powder I might give it a test.
