3 days late :-(

Sure wish I'd found this site three days ago, today was my 2nd trip to the range trying to get my new F1 master to give stable results

A model 1911 firing factory 45 APC loads measured 1743 fps. I tried distances out to 12 feet from the unit

A 45 colt revolver firing cowboy loads measured 1295, when all books say this light load should show 600-700 fps. again I was using distances from 8 to 12 feet, with and without the diffusers.

I went back today and re-did the same tests with just about the same results, except I took a 22 rifle
along as a test weapon. Firing stand velocity 22 long rifle ammo they clocked in at 2150 to 2300 fps. Monday it goes back and I will be ordering a CED M2. Many thanks for having this great forum.
