My wife shoots a bowtech tomcat, at 262 feet per second at 63 pounds, in 2007 at 18 yards she shot her first elk with it, she zipped right on through him. After the elk took off I went and found her arrow about 25 -35 feet beyond where the elk was standing. More important than the speed is the kinetic energy that you are delivering in my opinion. Like said you should not have any issues.
