Another shooter in the house

Really excited to be a part of this forum. Quick question for y'all, what powders are you using when you're shooting at high altitudes? I've been experimenting a bit and noticed some differences in burn rates and consistency. I'd love to hear your thoughts and share some experiences!

High-altitude shooting can really throw some unexpected challenges your way, and figuring out how your powder performs is often one of the toughest parts. Luckily, you’ll find a bunch of reloaders and long-range enthusiasts here who have faced that same issue, so you’re definitely in good company. We’d love to hear about what you’ve tried so far. Can’t wait to see your contributions and dive into some great discussions!

I use the most temp stable powders I can find. They all change a little bit with large temperature swings, but you don't want wide swings. Elevation doesn't change the burn rate, air density is what's affecting your DOPE more than anything. Bullets are slower at lower elevations than higher, as they have to plow through denser air. Same goes for early morning vs. mid day and evening, bullets are slower in cold denser air than warmer less dense air.

Use a good ballistic app that allows you to change elevation and temps then you'll be close. Get to your hunting or competition a day or two early and find a place to shoot a few rounds and fine tune your dope. You'll also have time to acclimate to the higher elevations especially if coming from sea level to hunt the high country.
