Feed it what it likes and it makes you happy. And it don't like factory anything so far....Winchester, Hornady, in multiple weights and offerings.
But with 34.5 gr of H335 behind el cheepo 55 gr Dogtown bullets, it places all of them in 3/4 of an inch at the 100 yd line. I had the chrony with me, but was so busy resighting all the wintertime scope swapping, I didn't get to use it. Oh well, at least I have a good starting point to work from with load data.
38.5 of IMR4064 gave me just under an inch also with Hornady 50 gr VMax bullets.
I have to try a few more powders and bullets, but at least I have a load that will work in the early summer PD fields.
