I was wondering if anyone knows the speed of the Liberty VFT set at 80 lbs. at 5 grains per pound at 30" . I' m assuming the ibo speed listed on their website is 70 lbs. (300-308 FPS) I figured the extra 10 lbs would translate into approximately 10-15 fps, but was not sure. If so, the 80 lb Liberty' s speed should be right there with the Patriot SC with the extra 1/2" BH and Freedom Cam!!!!! Thanks for any info.
