+1^^^H414 has been my go to powder in my 22-250s and Swift I also used WW760 in my 17 Rem which is essentially the same powder. I did notice the velocity was down in the 17Rem in the Colorado winter by almost 200 fps, perhaps a magnum primer would have helped it. I put a new barrel on the 17 as it was shot out which I'm sure contributed to that issue as well. I wouldn't hesitate to use H414 in your 22-250 during the winter but I would definitely chrono your load or at least check your zero in the weather you plan to hunt in. You can't give any advantage to Ole wiley at all.

41 -Have a newer 22-250 & a stock of H 414. Good for year round use? I'm in NW Montana so hunting temps range will likely be Winter zero to 90 degrees in Summer. If it's over 90 I'll be in the lake.

Yup for, Mid sized 7 MM's,. It's Perfect !Not a 22-250, but used the heck out of H414 in my 7mm-08AI year round.
I'm in central PA, so aside from possible altitude and humidity levels, I shoot the same temperature swings.
Unfortunately unless you have an old stock of H414, you are now going to be shooting W760.Yup for, Mid sized 7 MM's,. It's Perfect !
I Use, H-414 in my 7 X 30 Waters, 21" barrel, Contender Single shot with 120 grain, NBT's, in the Fall for Hunting,..
Varmints / Deer and with the weather being, NEVER over 90 Deegree's SO,. NO,. issues !
This Load is Sub, 1 MOA,.. easily !
Yup,. I've Got a couple of Pounds of it, "set aside" and WON'T be using, this Powder for, anything else but,..Unfortunately unless you have an old stock of H414, you are now going to be shooting W760.
I haven't tried the W760 yet, but supposedly it's the same powder.
Hell yes !!!Heat sensitivity isn’t an issue until it is. When things go wrong it is not pretty. Being the slow learner, it took two booms to learn my lesson. A person can go years or decades without an issue but that doesn’t mean the danger doesn’t exist.
