I had hoped to have chronoed both the Liberty and the MM VFT this weekend. A problem arose in that the cold weather seems to have an adverse affect on my chronograph...and I do not have an indoor lighting unit to use instead. I intend to rectify that in the next few days with the purchase of a new unit and light kit.

Something to consider though is that the speed rating for the Liberty is between 300-308 fps without the hush kit installed. The hush kit usually reduces speed by 3-5 fps. This may account for the difference between the listed speed rating and the rating that HF found provided the hush kit was installed during their testing.
