[QUOTE="Cold Trigger Finger, post: 733771, member: 56732"] As it turned cold again I was staying home today to keep the house warm. I figured it would be a good time to do a little Chronographing. I put the rifle and ammo outside for 45 minutes with the bolt open. I got the chrony ready and went out in the yard with chrony and rifle. Set chrony down, turned it on backed off 18' and commenced fire. Temperature -40°f Rifle, Ruger M77 Hawkeye Stainless Cal. 6.5 Creedmoor bullet, 110 gr Barnes Banded Solid moly tumbled Powder, Varget. 39 grains Primer CCI 200 1, 2931 . 2, 2931 . 3, 3007 . F. P. S . I have chronographed this load at 40°f and got 1,3040 2, 3020 3. 3034 . Same distance to chrony. I didn't have any high pressure signs and I don't think I'm at Max. [/QUOTE]
