Here is how I look at it... your bow shoots 245 fps.... the other bow shoots 308.. ok what is the speed of sound??? its like 2000 fps... (guestimate)no matter how fast your bow shoots its NEVER gonna shoot that fast... so oof course you want to shoot at a favorable speed but as long as you are accurate and QUIET.. then thats all that matters.. Im shooting 253 fps with 51lbs of KE.. thats PLENTY to kill lots of deer.. its been done with less.. I believe you have a great bow... be proud of it.. b/c if you second guess your equipment then you second guess yourself which throws off accuracy and self cofidence..
