RE: ABOLT 270 130 OR 140 GRAIN BULLETS
When switching from a conventional bullet to a Barnes X you need to clean your rifle barrel completely void of copper & powder fouling. The Barnes is a pure copper bullet and the gilding metal jacket fouling of the ballistic tip will only cause the Barnes to foul heavily. You will also need to readjust your scope for the Barnes bullets as point of impact probably won't be the same at the ballistic tip. I've used both bullets and had good success with both. If you like shooting in the kill zone behind the shoulder I would use the BT. If you like shooting in the shoulder I would use the Barnes. I would stay away from the Barnes if shooting in the rib area because unless you encounter a rib it has been my experience the Barnes passes through with little or no expansion.
