Greetings,
I am getting ready for a long range clinic and I would really use my M1A instead of a bolt action or my 223 AR.
After tens of tries, I can't find a load that will perform consistently in my M1A (in 308 of course).
One day, I'll get sub MOA groups with one load and the other day I'll get 4 MOA groups.
As of now, the groups who gave me one day sub MOA and crapola groups:
Nosler HPBT 168 grains, 2200 Sierra, Gameking Sierra, A-Max 168 gr
40.1 gr I4895
40 gr WC844
Yesterday I though I got the winner with Hornady SP 150 gr. with WC844 43.5 gr. The bullets holes were all touching each other in a 5 shots group. Then, the next 2 groups were 3 MOA. Moreover, when shot with my Howa 1500, I noticed quite a big flash at the muzzle that meant for me I should bring down 1 gr of powder.
BTW, with my Howa 1500, I can get very satisfying groups with those loads.
Anyway, anyone has a pet peeve load with I4895 with Sierra 2200 or Nosler HPBT 168 gr bullets?
Oh! I forgot to mention using one of those 2 powder. I did some reading and now I am trying the classical 41.5 gr of IMR 4895 under the Nosler 168 gr HPBT.
BTW, Any of you noticed a precision difference between the Sierra 2200 and the Nosler 168 HPBT?
Thank you
