My reccomendation would be to return the bst's to the shop. I tried them in my 7-08AI. The rifle has a 26"tube and due to the velocities I have been able to get while still keeping pressures at a sane level it is considered to be a "fast" barrel. Accuracy was so so with the bst. But on game performance SUCKED. Bullet exploded on impact at 175yds. Deer was shot BEHIND the shoulder and bullet never penetrated. The blood trail resembled a deer shot with buckshot. Needless to say I never recovered that animal. Crappy part was it was a legit B&C buck. Now, I shoot barnes bullets only. Accuracy is great and on game performance is devastating to say the least. Lighter bullet weights can be used with out fear of bullet failure. I have never had a barnes fail to do its part if I did mine. The only negative point to the x bullet I have found is my tracking skills have gotten to be a little rusty. Havent had to track a single animal yet.
