Last post PPL tried to help me and answer my question, which I appreciate, but I apparently did not give enough information. Here it is again, with info asked for, if someone would not mind trying again. Thank You ahead of time for the assistance.

I am shooting a PSE Firestorm Lite, rated at 300 IBO. I was shooting 72 lbs., with a 28 1/2 inch draw, carbon express 400's, Blazer vains, muzzy 3 blade 100 gr., through a Whisker Biscuit, Cronyed out at 256 fps. We dropped it back to 55 lbs. and it is shooting 230 fps. Does that information help more.???? I am not grouping well, and the arrow seem to be going in at abit of anangle with the knock to the left of the tip. Are my arrows over-spined now since I dropped back to 55 lbs?
