Has anyone had any luck with the 7mm stw 168 Long Range Accubonds with a 1/9" twist barrel? My issue is that I hunt at an altitude not much over sea level most of the year and only get to go out west once or twice a year. I want to use the same bullet and load everywhere I hunt. The SG calculations say it's marginal at that low altitude. I am just wondering if anyone has been shooting this bullet at less than 1000 feet above sea level with the same barrel twist? Thank you!
