i have used doubletap ammo lrx 127s 0n antelope and out to 600 yds at the range, like them alot. i am not reloading. using a sauer with a 1-8.66 twist
I also have a 6.5x55 barrel with the 1:8.66 twist. When I talked to the technical experts at Barnes they told me the 127 could have stability issues in certain cases, so I avoided it. Based on your experience, I will give them a try. I do use them in my 1:8 6.5-300 Weatherby.
