Spoke to Jes the other day about getting my stainless tikka T3 06 re bored to 35. Stainless is 25$ more. So 275 if not the basic 3 groove 1-14 twist. What twist are you thinking of doing and why?
1:12 to better stabilize 250s & up, in .35W. The CZ 550 Kevlar Carbine in 9.3x62 has a 1:10 twist rate, in contrast.
High noon, I know you keep saying the CZ550 carbine 9.3x62mm has a 1 in 10 twist, but it has a 1 in 14" twist. Just like their CZ 550 Americans'. I can attest to how well they shoot 286gr. partitions, 285gr. Norma Oryx, 270gr. speers and a couple others. They know what they are doing in regards to twist rate and building barrels and rifles. Good luck with your endeavor..
