Has anyone here had any experience with the 110 SMK?
A friend of mine use it for prs matches in his 7 twist 6xc.
He runs them at roughly 3000fps and about 0.02 from the lands with good results. Not quite the groupings as with 105 bergers but the bc makes up for it.
Going to try them for fun in my 6br this summer
Tried them in Dasher and 6BRA, both 7.5 twist. Could never get them to shoot consistently like the 105 Hybrids. They'd bughole one day then open up the next. Flew nicely with good BC, but I'd rather have the consistency and precision so I have stuck with shooting 105's.
Sierra recommends a 7 twist barrel. Perhaps that helps explain the inconsistent results.
I tried them in a 7.5 twist Bartlien. They shot nearly as good, but not better than 108 bergers. I don't currently own a 7 twist like sierra recommends.
I tried them in a 7 twist Mullerworks 26” Barrel chambered in 6 Creedmoor. Multiple outings with two different powders and never could get them to shoot consistently. Switched to the 108’s and immediately produced fantastic groups.
I’m shooting a 7.5 twist 4 groove running them at 3,120 FPS. I’ve only dropped 6 points in the last five 3x600 yd. matches using a sling and coat so I’m sold on them.
I hope this helps,
They aren't as easy to work with as 107SMK's or 108 Berger's but when you find the right combination they shoot very well in the wind!
I worked hard to get them to shoot for me in my Dasher as well, 1:7.5 twist. As above, would shoot well one match, then struggle the next. Shot clean at a 600 yard fullbore match, to turn around the next weekend and shoot a 587 in a 3x600 match. I had unexplained vertical flyers with both powders that I tried with multiple seating depths. Switched to Berger Hybrids and I am back to shoot <1" groups at 300 yards with very little load development. Substituted a couple of Bart's bullets with similar (little better) groups with no load development. I still think they are worth pursuing them, but I would go 1:7" if I were to chamber a barrel for them (probably will next barrel).
I put a Shilen 1/7 on and have about 500 rounds through it now with the 110smks. I tried a few different powders but in the end I settled on RL-15. I'm getting .3moa when I do my part. I havent stretched it out yet but the nice weather is near.
I may give them a try. The bc is awesome!
