which twist for 107 smk & 105amax

[muzr257]

Hi all
thinking of building a 243AI to shoot the 107 SMK and 105A-max - what would be the reccomended twist rate?
If I go 1 in 8 will I also be able to shoot the 87 V-max?

I'd go 1:8.5". A 1:8" will work also, but at the speeds which a .243AI is capable, you can get buy with the slightly slower twist.

Yes, you can shoot the 87gr V-max just fine in an 8-twist bbl.
