I have had some good talks with the nice folks at Underwood

I have some velocity measurements that are a bit more specific

Using a 3566 Limited and a 3566 compact

The 5" barreled 3566 Limited produced an average of 1450 FPS

The 3 1/2" barreled 3566 Compact produced an average of 1350 FPS

The 124 grain Nosler JHP penetrated 14 1/2" of ballistic gel
