Jared,
Up until a few months ago, I would have agreed with you. But in the past few months, shooting a .25 Panthera 600mm with Altaros ATP Smooth 49.5 grain BT slugs at about 890 fps, I know differently.
Yes, the gun has a VERY good barrel, and I feel like I won the "barrel lottery" with this one. I also have the gun tuned mildly, at about 87 FPE, so it's easy to shoot smoothly, and also shoot with a VERY low SD, less than 2 fps.
But the KEY to shooting long range in other than ideal conditions is BC.! I agree that the 'Tuber vids showing long range are almost always in ideal conditions. But when we shot the long-range event in Oregon April 30th (120 to 240 yards), the wind was anything but calm. It was mostly over my left shoulder from 5 to 10 mph, with gusts to higher, and changing directions.
The BC of G1 0.21 (I used an equivalent G7 0.111) made shooting fairly easy. I knew I had my dope worked out for distance, so all I was concerned about was windage. For most of the targets I held left edge middle height and pulled the trigger. For the 240-yard target to the right of the rest, the wind was directly at my back, maybe even a bit right to left, so I held middle-middle. Having shot the gun/ammo in similar conditions with my buddy Gerry
@Gerry52, I was confident in my set up and knew if I did my part I wouldn't miss. And I went 25/25 for a perfect 250 score.
I was playing the odds for each shot, but reality is that most of my shots were closer to the left edge than the right edge.
Prior to Oregon, I had worked out the DOPE and verified out to 286 yards, so further than that I have no idea. The gun/ammo combo is definitely "minute of squirrel" out to that range...
IMHO, these .25 Altaros ATP Smooth 49.5 BT slugs are "next generation" and significantly more advanced than anything else on the market... https://www.airgunnation.com/threads/altaros-b-c-set-a-bnew-standard.1289204/#post-1493648
