I was wondering what rate of twist would be best for 107 and 123gr. smk's wouldn't be shooting anything lighter and max would be 130gr. bergers. I have a .260 with a krieger 1:8.5 and it loves the 130gr. bergers but so far doesn't seem to like the 123's. Probably be getting a broughton barrel would a 1:9 or 1:10 be better? Thanks

8 and 8.5 twists work fine for my 142's so 9 or 10 should be fine for 120 grns. I would think.

Re: need input on .260 twist rate
If you are thinking you might shoot the 130 Bergers, I would play it safe and use the 1-9. 1-8 will still shoot the lighter bullets but allow you to go heavier later if you decide to. All my .260's really shined with the 140's. I did try and shoot the 120's and 123's for a while but ended up going back to the 140's.
good luck,
JamieD

Re: need input on .260 twist rate
Thanks, I'm pretty much a speed freak so I definitely want to stick with the lighter bullets and get a slower twist than what I have now.

I would go with an 8.5 twist on the barrel. I have had great success with this. You can shoot both of the bullets with no problems. Good luck

So you appreciate muzzle velocity over impact velocity?

I am shooting a 9.1 twist Obermeyer with my 6.5x47L. This twist is what Boots recommends for the 6.5x284 with 140-142 range. I bought it from a 1000yd shooter and gave it a try as I wanted an Oby and it was my only choice at the time for twist etc.
Haven't tried the 130's yet but with the 123 Lapua I ran a 10shot string @ 3015fps with an SD of 4. Load was 38gr of RL15 and CCI450. Jumping it .010. Shoots excellent and is a 28" tube. Need to work with H4350 a bit more but don't think I might get that velocity. Most are stating best accuracy etc around 2900-2950 IIRC. Mine has been a safe queen for almost a yr. Too many toys I guess.

Re: need input on .260 twist rate
Would a 9" twist stabilize the 130 and 140 VLD style bullets?
Ive heard 9" will work up to 130 standards, but with VLD's you need to speed it up???
