On the .260 142g SMK box, it says they are designed for 1:8 twist barrel. Is it worth running them through a 1:8.5 barrel or would another weight bullet be a better choice?

Kumaichi,
They'll work just fine, no problem at all. Sierra does their in-house testing with 1x8.7" twist barrels for these and they shoot just fine.

Shot to 950yds with my 8.5tw Kreiger and had no problems.
they should work fine, I mean I know they'll work in my 1:8 barrel
Thanks guys for all the info, guess I'll be buying some 142g SMK's then
