I decided to split this Field Test Shooting Review of the Umarex Colt Single Action Army into two parts since i wanted to do multiple tests with multiple types of ammo and dummy shells. at the end of the video I also throw in my Cybergun / KWC 1911 Blowback BB Pistol just for fun since both of these pistols where used in the US Military.
I start off by testing out the Umarex Colt Single Action Shell Loading BB Revolver shooting 6 rounds through my Chronograph using the included Umarex Dummy Shells with steel 5.1 grain 4.5mm BB's since this is what most people will experience. In my second test I switch up the ammo slightly and try out some much heavier Lead BB's that are a bit larger than 4.5mm (about 4.7mm) and weigh in at somewhere between 7-8 grains.
On my third test I go back to the standard 4.5mm Steel BB's but switch out the included Umarex dummy shells and replace them with some Dan Wesson Dummy Shells. Both shells are about the same length and width but with the included Umarex shells, you load the BB's into the back of the shell. With the Dan Wesson shells you load the BB into the front of the shell.
Of course lastly I bring out my KWC Cybergun / KWC 1911 Blowback BB Pistol and put 6 rounds through the Chronograph just for fun :)
You can watch the below video to find out how each shooting option worked in the Umarex Colt Single Action Army Shell Loading BB Revolver, to quickly summarize how each 6 shot gun averaged out:
The Umarex Dummy Shells with 4.5mm Steel BB's shot just under 400 fps.
The Umarex Dummy Shell with 4.7mm Lead BB's shot around 270 fps.
The Dan Wesson Dummy Shells with 4.5mm Steel BB's shot just under 250 fps.
My Colt Government 1911 shot pretty close to 300 fps using standard 4.5mm Steel BB's.
