Winter ELR rifle systems ?

I swear years ago I seen a Video of Chuck Adam's hunting in blueJeans and a plaid shirt ...he smacked a monster with his Bow !

I don't own any rifles that have POI shift due to either barrel heat (cold bore) or from fouled condition. If I discover a rifle doing this, and the usual accuracy work doesn't change it, ie bedding, floating and pillaring, I don't keep them.
My rifles HAVE to put the first shot where I aim, I will never compromise on that, ever.
There are certain powders that DO show POI due to the temperature, but, if you avoid those, it will never rear it's head.

Cheers.

Could one reason for those "mysterious
misses" / "differences between the first
and the second shot" be that the
rifle system (rifle-barrel-scope-mounts-
rings-screws...) has been kept warm
in vehicle (offroad car/...) while travelling
to destination and the temperature
difference may have been over 40°C (100F)
between the first and the second shot ?

ref 1:
"in colder temperatures bullet speed
differences may vary between 5-20m/s
depending on the rifle and ammo
due to barrel heating"

ref 2:
"mysterious shots" right ~0,5 mrad !

ref 3:
"make sure you tighten your scope
properly for which you need strong
screws and rings designed for colder winter
temperatures"

ref 4:
"riflescope slipping occurs more often
in cold temperatures"

Have you noticed any difference
between the first and the second shot
accuracy - after all the temperature
difference in the rifle barrel must be
considerable between those shots
in cold winterly conditions ?

The first shot is what I'd worry about on a cold bore. If for some reason I needed a second shot and it wouldn't follow with the first, id be looking at the rifle pretty hard. If I couldn't get it to stop I'd get rid of it like magnum said. All of my customs follow the cold bore shot. Maybe I'm just Lucky they do? But that first shot cold bore is what matters most to me. I don't think camo will matter unless it's walking over top of you and I'm just partial to stainless!

Don't know whom, or what you are quoting, but sounds like noise from someone that doesn't hunt with a controlled load, a rifle worth a **** or any experience in such matters.
As I stated, I do not own ANY rifle that changes POI due to cold, heat or fouled/cleaned condition. Such rifles are not part of any controlled system, which includes all the other things you mention.
If you are so inclined to be concerned with what you have quoted, don't shoot in the cold…or the heat either for that matter.
Guessing is not my forte.

Cheers.

has anyone iused
expedition sled
while ELR hunting in snowy winter
conditions ?
if so,
did you use the sled as support
when shooting ?
did you keep your ELR riffle in sled
when skiing or did you carry the riffle ?
did you have the sled tied
in your car roof rack or inside your car ?
did you ski or use snow mobile ?

Isn't black/red plaid with blue jeans the best elr camo ever made?? That's what my grand pappy said

lets say, same altitude and a very damp to almost rainey day with temps in the 40's, then change to a day (same altitude with temps in the 110's.............you still have the same 0 (zero)...if so, then that's a point of shift/aim right........i'm asking as i only shoot in weather in the 70-100* range w/o shift or aim issues. vertical is more of an issue than horizontal as the winds get really mixed up/changing.

My question is this, what powder is going to give you 10fps change from the 40's to 110's?
I can tell you there are several powders that will do this, if you don't test you will NEVER know.
I don't know Fahrenheit, I know Celsius and my loads do not shift point of impact from -8°C to 40°C due to elevation or humidity because of the powders I use.
I know very well how some powders shift with temp and elevation, which is why I avoid them.

Cheers.
