    Wow, I’m surprised you are shooting 24.2 of N140 with the 90s. My go to bullet these days is the 80gr ELDm from Hornady and I’m getting 2,700 fps out of them with that same powder charge & LC cases.

    My barrel is a Bartlein 6.5 Transitional and it has a Wylde chamber. I don’t think I could shoot that much powder. We tried 23.7gr in a buddies rifle and it was popping a lot of primers. Incredible accuracy, but too much pressure. It was fine in my Bartlein, but his was a White Oak and it would not take that much powder.

    Thanks for sharing the information, very informative.

    Oh that’s good to know! What’s your elevation where you were shooting them? We were going to be shooting 1K at sea level, so I was a little concerned. I ran the number through Applied Ballistics and they seemed to be right on the edge of supersonic.

    We are using N140 and getting about 2,630 fps. I’m pretty sure Varget has a little more energy and can produce better velocities though. We did try N540 & PP2000 but just could not get the accuracy of the N140.

    We have had good luck with the 90s out of Wylde chambered 1/7 Service Rifles, but that was only shooting them at 600 yards. We had planned to go to a 1K match, but it got rained out. I would be cautious if you are shooting them on acoustic targets at 1K, as I’m not sure that they give enough of a crack to make the targets work reliably. If you are shooting paper, the 90s should work really well.
