I received that exact comment about the Hornady dies just the other day!
I ordered my 22" from Ritch Monday. 58's at 3650 as easy as pie. No brainer!
I,m not sure you will see 3650 fps with a 22" barrel unless it's 10 twist then maybe. I have 22" 6DTI ( which holds more powder than the 6-6.8 )with a 12 twist and I am around 3560 fps with 58 gr vmax. If you get that speed that would be great. My buddy has a 24" 6-6.8 from ritch and he shoots 58 gr vmax at around 3450 fps.
My buddy's 22" 10 twist from Ritch clocked over 3700 with h322. We backed it off to 3650 ish to tight up the spread a hair and we felt sorry for them poor coyotes lol. If it won't cooperate with the h322 we will be happy with being in the 3500's and 8208.
I was a bit shocked when they hit 3700 plus and my graph is nothing to special but it sure doesn't seem to be any too generous.
This is my gun he is talking about. Just want to confirm that this is true. Chronograph verified. 3720-3730 fps was 31.5 of h322. We backed it off to 31 grains and the group tightened and the standard deviation was very low. Using CCI 450 primers. Its shoots 75 v max 3330 0.5MOA with 30 grains of AR Comp.
