I would consider 24" to be a couple feet. Couple usually refers to 2. In this case my "few" refers to about 3-5 ft.

I would also note I shot this distance during near perfect conditions. Little or no wind or mirage. And did not hit 100% of the shots. I've also shot many distances less than 1760 and learned my rifle and its ballistics very well.

Since you asked- Leica, Custom 260, Sightron SIII, Strelok, Kestrel, Rear Sandbags, Harris, 2835 fps (added suppressor since then), 142 SMK/Lapua Brass/H4350/CCI BR2.

I'm not trying to cut you down. You make some good suggestions for ELR shooting. Spotting/Seeing Bullet splash being a key to dialing in. But with a good consistent gun/load and a good ballistic app (or in my case real results from past shooting sessions (DOPE) it is not unrealistic to get better results. I've shot a decent amount around 1500 yards which in turn gave me a better idea of what performance I could expect at a mile.
