Sabot's in F-open?

but it seemed like a waste of time

Oh it was... But it makes for a good story years later...

i'd start by calling the bullet mfg and inquiring about max velocity. if you push some of the long skinny bullets too fast, they are prone to disintegrating mid-flight due to the rotational stress

Saw it happen to a guy at the F Class match I was at week before last. He was shooting DTAC 6mm in a 6XC. Shooting at the 500 yard line and his bullet came apart at 200 yards. As Walter said in "The Big Lebowski"....

"...Mark him zero....."

I tried some 75 gr Hornady A-Max in my fast twist .223 meant for 90 gr.
I got one string that was nothing but 10s, Xs, and misses. Scorer said he could see the silver streaks in air as they broke up.
Loaded them down a bit and they shot great at midrange.

I had been losing 90 gr Sierras in flight, too. I fixed that by going to JKL and Berger.

Interesting notes on bullet breakup, thanks everyone!
