Yes….about 1fps per degree. A2520 is temp sensitive for sure and can have pretty big spikes at max load in the sticky hot summer. This particular load doesn’t have that issue in my guns.
I also have a A2520 55sp load that shoots lights out but I don’t remember the charge off hand. My oldest son took his first deer with it out of a 18” ar. Perfect shot behind shoulder at 40y and ran 30after. No drama.
Honestly have yet to loose one to a .223 in our sample size of about a dozen. Hunting mentor buddy always has a reason it won’t work next time though.
