Twist rate for Sierra 7mm 183gr matchkings

Post by GlennA »

Do the Sierra 183gr projectiles shoot ok (good/bad) in a 32” Bartlein 8.5Twist 284 barrel? Has anyone had any problems?
There’s a reason for everything!

8" would be my first choice, 8.5" will work, but you may lose some B.C. at 9/1000 yards.
