[QUOTE="RockyMtnMT, post: 852728, member: 7999"] How long is the barrel? I will be starting load development at the end of the month on what we are calling a 6.5 ultra cat. The reamer is based on the 300 rum with a 40 deg shoulder. GS Custom made a 128g HV for us to shoot out of this chambering. 7 twist is what we are running on 30" length. These bullets are going to have a bc around .640. Running them near 4000 fps will make this chambering a legitimate long range contender. If were not for the GS bullets we would not have done this because of the barrel life and slow powder issues. As well as the problem of conventional bullets not being able to stand the launch. We may take one of these barrels and run as many as we can to test barrel life. GS is willing to give us the bullets if we document the shot numbers. I am not sure if we want to donate the time and other recourses needed to do that. We will decide later. Needless to say, I am very excited about this. It has been a long time waiting. I was not going to say anything until we were able to shoot it but this thread seemed like a good time to say something. When we start shooting I will give reports as to how it goes. Steve [/QUOTE]
