Thanks, John
The .300 Weatherby is the only cartridge I use RL26 in. I’ve only shot it at about 14 degrees F on the low end after the ammo can sat in the truck at -9 F overnight. I only shot 2 rounds to confirm zero and commenced to hit 200, 300, and 400 yard gongs at the Bears Ears Sportsman’s Club in Craig, Colorado, so it was not a very scientific cold weather trial. It was cold enough that hunt to freeze the balls off a brass monkey! I only fired 1 round that hunt at a little over 250 yards and it resulted in a dead elk hit pretty much where I aimed.

However, I will take your advice and transition that cartridge to RL23 or back to MagPro for cold weather hunts.

Cheers
