[QUOTE="Salmonhead, post: 2810065, member: 117979"] I've had two Caldwell chronographs and they varried wildly. Id use them simultaneously and consistently get about 70fps less from one of them. They were really bad when the sun was lower in the evening or if it was partly cloudy. Readings all over the place with known loads. I've also had poor results with winchester brass on at least three occasions with different chamberings. If the fire formed brass doesn't start behaving, I would switch to adg or Peterson. I also wouldn't be messing with 5/8" results from a stock Tikka barrel thats 10 years old. I'm my opinion, to drop that group, you'll need a new custom barrel. I also think your charge weight is several grains light. But if you're happy with 2700, it won't hurt anything. You're leaving an easy 250 to 300 fps on the table if you feel you could use the velocity. [/QUOTE]
