The cold can affect burn, but the bottom line is you just need to shoot it and see. It is likely you will lose a few FPS in the winter but it might not make any difference as to how it shoots. I don't like having two loads for a rifle, it is hard enough to get to know one rifle
If you were shooting bench rest it would be an issue, but for varmints I dont see a problem. Mine is a 1/2 MOA gun or better all year round.
21.5 grains of H4198
40 V- Max light in the lands
"This is a max load and may not be safe in your gun work up with care"
I work up all loads in the summer is I can (all max loads) so I wont have problems in the winter.
I have seen max loads worked up in the cold that caused big problems in the summer. I sont think you will see problems with H4198
The old 222 is a blast for G-hogs and fox. And on a calm day the little A-Max can get out there and still so some damage.
