He steered me to a 1-14' twist after asking about other options. I went with a medium contour 24" Shilen barrel, works for me.
If you stick with the lighter bullets, a 14 twist will do just fine. I have seen comments by ballisticians from a couple of different bullet makers stating that 52g bullets are ideal for a 14 twist 22-250.
The problem is that the better varmint weight bullets are all too heavy/long to work well from a 14 twist. IMO, the 14 twist is obsolete and should be replaced by a 12 twist as the factory standard. My 12 twist Shilen shoots much better than the 14 twist barrel that it replaced. Granted, the Shilen is a better quality barrel than my previous barrel. However, it is shooting the 55g bullets very well. That is something that my 14 twist just would not do.
I can't wait to get my hands on some 53g VMAX's to see what they will do from my rifle. The 12 twist will also let me step up to the 60g Nosler Partition or the Nosler 64g bonded bullet if I need something a bit tougher. The extra flexibility of a 12 twist is worthwhile, IMO.
