That’s for a .44 mag pistol. Here’s the actual verified data for my 12 gauge rifled barrel with Hornady 300 gr SSTs at 6000 feet elevation.
300 gr bullet with a .2 G1 BC
Barrel: 2010 FPS
100y: +1.6” 1702 FPS 1900lbs energy

300y: -33”. 1230 FPS 997lbs
Seated, arms over my knees. A position I've practiced out to 500 yards and it's my favourite fast/stable postion to use (shot a coastal blacktail @ 420 yards in that position, bang flop). But this time I was sitting to stay concealed while calling. The bull walked into the clearing and shot him at 25 yards
Ditto on the fallen log. Was rock steady. Clean missed one the day before, standing with sticks, while under duress. Never again. If there's a tree standing or fallen, I'm using it. Using sticks during a quick fluid encounter is only asking for problems. If I'm sitting with sticks and have time to set up properly, maybe.
Off hand at about 50 yds. It happened fast and I was still wearing my backpack. I've shot variations of @Formidilosus drill some over the last year some (not as much as I probably should have) and I'm kind of glad I did.....
So I'm on my third year hunting elk.
2019 - I missed at 440y laying prone. Spent a lot of the off season working on my shooting.
2020 - 2 elk: cow at 33 yards siting, rifle resting on one knee & then a bull at 40 yards, standing off hand
Had a miss on a late season cow at 520 yards trying the tripod for long range for the 1st time.
Did a ton of work on the long range efforts in the off season.
2021 - 2 elk: bull at 140 yards, standing, rifle rested on a pine branch & then a cow at 650 yards, sitting, off the outdoorsman's tripod.
