I live in Southern Arizona and specifically use RL 26 for the 6.5 PRC. I don’t experience any pressure spikes and minor velocity changes from 55° to 95°. Velocities range from 2936 to 2954 fps with temperature changes. Acceptable in my opinion
EL glass is impeccable! Rangefinder is spot on with my sig2400 abs ballistics. They range lightning fast out to FOREVER! The app could use some improvement but is easy to use and set up. Still working out the Tracking Assistant. Hope that helps.
I use the Alaska guide creations for my 15s. Lots of pockets and it attaches to my pack. I also use the marsupial full closure with my 10x ELs. It does great with keeping dust out.
