Why 1:7 twist for .244 Valkyrie?

[ericbc7]

why in the world are the .224 Valkyrie barrels 1:7 twist when years of competitors know that you can’t stabilize a 90 gr smk properly with less than a 1:6.5 twist?

Probably to shoot their 90gr Fusion hunting bullet and lighter ones.

7s do fine with the 90 SMK. It's the Berger and JLK 90s that need a faster twist.

Actually with the extra velocity and depending on the ALTITUDE(s) you will be shooting at a 1-7 could work quite well with our 90gr VLD.

I had excellent results with a Krieger 1-7tw on a M700 in 223AI several years ago. It was finished at 26", and shot several 1/2 MOA groups at 1000yds. OTOH, the last 1-6.5tw bbl I had on an AR15 match rifle blew-up just about every bullet I tried in it, including S77MKs. If it really does take a 1-6tw bbl to stabilize Sierra's new 95gr MK, I'll pass...
