Hopefully we are back in business after the YouTube Attack on Airgun channels. I'm still waiting for YouTube to get back to me on the video that they put a strike on. I did appeal the Strike but so far YouTube has not responded...
We must push forward and so here is my first video back and it's a good one! If you haven't already watched my Table Top Review of the Umarex SA10 CO2 Blowback Pellet and BB Pistol, make sure to check it out for details and some nice up and close video of this fine dual ammo CO2 air pistol.
As always during my indoor Sea Can Field Test Shooting videos, I first test out the velocity of each gun. Since the Umarex SA10 CO2 Blowback Pellet and BB Pistol can shoot both 4.5mm Steel BB's and .177 caliber pellets I tested both ammo types using my Chrony Chronograph. I fired three shots of each ammo to get an average fps velocity. Interestingly the heavier 6.9 grain lead pellets had the higher average velocity of 376 fps versus 304 fps with 5.1 grain Steel BB's. I have a feeling the lead pellets fit the barrel more snug and did not let any of the CO2 blow by creating more back pressure and a higher velocity.
After my velocity test I proceeded to find out which ammo type was going to be more accurate with the Umarex SA10 CO2 Blowback Pellet and BB Pistol. Since each rotary magazine holds 8 rounds it made sense for me to put 8 shots of each ammo type into the paper target setup 30 feet away. Keep in mind the Umarex SA10 CO2 Blowback Pellet and BB Pistol has a riffled barrel best suited for lead pellets so going into this test I was expecting the pellets to be the clear winner here.
I was able to get about a 2 inch 8 shot grouping using .177 caliber lead pellets with the Umarex SA10 CO2 Blowback Pellet and BB Pistol. All shots where fairly well centered but I did notice that most shots actually hit all within a very tight 1/2 inch group with 3 shots coming out a bit and extending the grouping more or less vertically. Switching up the ammo to steel BB's and as expected the groupings extended to about 3 inches with one outlier hitting very wide for some reason? Even with the steel BB's shot placement on the target was well centered in general.
The blowback on the Umarex SA10 CO2 Blowback Pellet and BB Pistol is very pronounced but does not rock your hands too much keeping this airgun on target between shots and the trigger is one of the best rotary mag type trigger I have tested to date, extremely smooth throughout the entire trigger pull. Overall the Umarex SA10 CO2 Blowback Pellet and BB Pistol has great looks, decent power and good accuracy going for it and could perhaps be one of my top pics if you're looking for a blowback pellet pistol option.
