Sapper, yes that was my thread. My 40 gr Varget load tops out at 800 yds on electronic targets. It’s running under 1200 fps at that distance and giving warning messages. But that is a great short range load with good accuracy out to 300 yds. I use it exclusively in 200 yd matches. But, I’ve had mixed results at 600 yds, so I will do some tuning of the load with the No. 4(T) to try and reduce the vertical stringing that sometimes occurs.

I got lucky on the .308 loads, the Varget powder charge required to work the electronic targets at 1000 yds also gave best accuracy by far at 600 and 800 yds. But it’s a stout load, the recoil is noticeably more than 40.0 gr. I’m carefully monitoring headspace and throat erosion to be sure I’m not causing excessive wear on the rifle. I plan to use it exclusively for long range use, perhaps 4 or 5 times a year.
