How many grooves you running?
I will be using 4 groove barrels, all of my fast twist rifles are running these with great consistency, moved away from 6 groove barrels some time ago.
Cheers.
Pleased with the 25 cal 131 SMK

I am running the 131 SMK in my 1:7.5" 25MBK. Been extremely happy with them.
I ran the old version of the 131 "SMK" (I won't name them because eff those guys) in a 1:7.5" 25SST @ 3199, and they were devastating on game.

I don't know if I will try with these. Sierra closed the nose so I think I would have to trim them to open them back up to be able to be able to hunt with them.

I can say they work well as-is. If you open them up, don't go too drastic. They get real nasty when you do. This was after opening them up with a #60 (.040") wire bit, and this is NOT an exit. It is from the temporary wound cavity. Shot entered the neck on the hard quartering to buck and burst him like a water balloon. I now use a #74 (.0225") and it performs far less violently.
