Pleased with the 25 cal 131 SMK

I have a 1-7 twist 257 bee. Been a finicky rifle since day 1, probably going to retire it eventually and just do a 25 Saum and be done.
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.
 
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.
