[QUOTE="TJW, post: 1006999, member: 12413"] Just fired the 225's with a 4-shot group. 4-shot was 0.488" and the 3-shot 0.306" My 1st, 3rd and 4th were all in a tiny group, but my 2nd shot opened it up to the 0.488" I had a chronograph set up with the following: 2805, 2807, 2799, and 2797 fps Avg=2802 fps SD of 10 fps From that I can see that I just needed to back them off the lands to decrease the pressure signs I was getting. That allowed me to stuff more powder in there and get a higher velocity. Thanks jfseaman [/QUOTE]
