While shooting my savage 10T-SR 6.5 Creedmoor when temperatures are colder than 0 celcius, the accuracy goes to sh!t. Took the gun out of the house and shot a 6” target@500yds 4 times in a row. Let the gun sit on the bench for a couple hours and went back at it again. It was then shooting 8” high. Went to the 100yd target and was 1.5-2” high. Took the gun inside and let it warm up for an hour. Went back out and zero’d at 100 and hitting the 6” target at 500.
Re torqued the stock, have had no success figuring this out. Anyone have ideas?
 
Just to be clear, was the ammo cold also? Due to the fact that your rifle was shooting high, personally I believe its a rifle issue, not a powder/primer issue. Cold weather has been known to cause improper primer ignition of certain powders, but to me, that would cause a lack of pressure, and a low shot.
 
Could be the scope is moving. You could try another optic if you have one. What kind of scope are you using? Also definitely check your mounting setup
 
They are hand loads(very precise handloads, not a newbie)
I had the opposite thought of the stock and that its contracting causing some weird torque issues
Both cold ammo and tried some warn stuff from in the house.
Scope isnt moving or the problem, worked on the last gun in the cold. Bushnell Elite Tactical 6500 4.5-30x50 in Alberta Tactical Supply rings.

Does your grouping move down as the rifle barrel heats up from shooting?
 
No, barrel heats up just barely when that cold outside. Definitely not enough to warm up the stock.
Again, this is why it has me thinking its in the stock and not the barrel or action.
 
Oil in the chamber? It would get cold and get thicker and get worse. Try a cold weather chronograph vs your warm data to see if velocity is changing.
 
I haven't tried mine in cold weather yet (same rifle). If I get a chance over the next few days I'll fire a few and see if my zero has moved.
I'm using H4350 and Lapua SRP brass with CCI BR4 primers. 123 gr SMK's.
Were you shooting off a bench, or bipod, prone?
If it was a bipod on frozen ground a high impact wouldn't surprise me.
