Getting ready for a possible disabled vet elk hunt this year or next year in ID. Thanks to Bryan at the Idaho Wildlife Federation for sponsoring me.
I am possibly taking two rifles, both in 7mm. 280AI and 7MM-08. Specifically for the 7mm-08, I have a 1:9 twist Carbon Six barrel and plan on loading the 139 Barnes LRX. Big Game gives the most bang for the buck, but also is not as temperature sensitive as other powders (.98 FPS per degree). Still, not too bad. I love the speed, accuracy, and low SD from Alliant powders. From Barnes, they list RL-15 and RL-17 which are not great. However RL-16 is fairly temp sensitive (.34 FPS per degree), but there is little data on RL-16 for 140 grain mono bullets.
Now, RL-16 falls between RL-15 and Big Game for burn rate. So, I am not sure why it is not an option.
Has anyone loaded the 139 LRX or any mono bullets in the 140 weight.
Thanks.
