In this Field Test Shooting Video Review I test out the brand new Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun in the Replica Airguns Indoor Airgun Range Sea Can to see what the actual velocity is along with accuracy. I first test fps using my Chronograph and I perform this test with and without the barrel extension to see how much the additional barrel length will increase velocity. I also shot the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun in both semi auto shooting 10 rounds into my paper target setup 30 feet down range and then I perform a full auto 25 round magazine dump to see if the grouping expands or not.
Staring with the velocity test I did use brand new CO2 for this and the temperature was around 20 degrees Celsius or 68 Fahrenheit so not too cold or warm. With the Barrel extension installed I managed to average 418 fps shooting 4 rounds. With the barrel extension removed as expected the velocity did drop a bit down to 373 fps shooting 4 rounds and averaged out.
For my Accuracy Test I placed the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun in semi auto for the first portion and fired 10 shots into the paper target setup 30 feet away, I was using a semi rested shooting position with a sand bag up front to rest the gun on and me sitting on a stool in the back. I did not sight the red dot in and found that out of the box the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun shot down and too the right a fair amount but at least I was able to get most of the shots on the paper target and on camera. The grouping was around 2.5 to 3 inches so not super great but not bad either.
I then flicked the main selector to Full Auto since this is what most people want to see. I also reloaded the magazine with 25 rounds from the onboard hopper and unloaded the full magazine in a second or two. I did aim a bit higher and to the left this time to get the shots closer to the bullseye and I was able to do so with most of the 25 shots all within about 2.5 to 3 inches so not really any difference shooting in semi or full auto at least in terms of accuracy.
As I mention before in my Tabel Top Review for the Crosman ST-1 CO2 Blowback Full Auto Steel BB Machine Gun, it is a bit different looking and for me took a bit of getting use to but the good news is that it performs about the same as the other Crosman CO2 Full Auto Blowback BB Rifles in this similar lineup so if you like the look then don’t be afraid to pick one up over on our Canada or US replica Airgun Stores.
