If anybody's hunting doesn't vary from the 20s to 80s, then the powder doesn't matter much--and even some parts of Alaska don't vary much from those parameters. But I would tend to use RL-23 over other powders mentioned (including RL-26) if any hunting would take place colder than around 20 degrees.
That's my thinking in building up these loads, ahead of my move to Montana in 2023. Have a 8 pounder of RL-23.
Have my long range bullet loading using the 150 grain ABLR all set, it's a RL-23 load. This 160 grain load will be my shorter range heavyweight.
The 130 Ballistic tip load for Pronghorn & Whitetail I'm planning on using some Reloder 16. Hopefully I can keep my old Tanger M_77 busy as I travel from Western Montana to the Eastern side.
