Re: 1:11 Twist rate??
I have a Tikka made by Sako, you probably have the same brand, or not. I have No problems with the 1:11 twist though I wish it was a 1:10. From what I understand Sako makes most of there tac. guns with the 1:11 twist. Also, if you didn't know the length of your bullet NOT weight should be the primary factor when picking what bullet to shoot. Though there is no doubt a coralation between the two(weight and length). Glenn Daughtry and Brandon Webb(former Navy Seals) have a great book out entitled 21st Century Sniper. It's a good read...
