[QUOTE="RockyMtnMT, post: 859109, member: 7999"] That would be amazing velocity for a 230. I have not heard of many getting that from a 200g AB with that barrel length. Given this kind of performance with the 230 berger you should be able to run the 177 up around 3700fps. The faster you push the GS the better the bc should be. As it slows it will degrade. When you get up over 3500 fps this should be so. If the Berger sheds half it's weight in the first few inches you are left with 115g to finish the job. VS 142g in the GS at 80% retention. Momentum is definitely on the side of the GS. Steve [/QUOTE]
