I have already reviewed several Crosman 357 Pellet/BB Revolvers in the past like the Crosman Vigilante which also has the ability to shoot both .177 caliber pellets and 4.5mm Steel BB’s, (Really they all are with the right magazine). With the Vigilante my pellet chronograph tests got similar results but with Steel BB’s the Crosman Vigilante did a lot better than my Crosman Triple Threat CO2 Dual Ammo Revolver using a similar 6 inch barrel. As expected both the Crosman Vigilante and the Crosman Triple Threat did about the same in terms of accuracy getting better results with pellets over Steel BB’s.
Starting with the velocity portion of my Indoor Field Test Shooting video, I placed a brand new 12 gram CO2 into the Crosman Triple Threat CO2 Dual Ammo Revolver and tested out some 7 grain .177 caliber Lead Pellets. I averaged 382 fps in what I would consider normal indoor temperature ranges so you can expect a bit higher velocities in warmer conditions. Moving on to 4.5mm 5.1 grain Steel BB’s, I averaged quite a bit lower velocity at 288 fps. I was surprise since it was almost 100 fps lower than the heavier 7 grain lead pellets. The logical reason for this is that lead Pellets fit the barrel much more snug, stoping any CO2 from getting around them which helps increase the velocity over Steel BB’s which are a hard metal and need to be slightly smaller in diameter and therefore do let some CO2 get by reducing the pressure behind them.
For the accuracy porting of the the Indoor Field Test I shot 10 rounds for my pellet magazine first and then 6 rounds for the BB magazine, simply because this is how many rounds each magazine holds… Makes sense right? Even with the pellet magazine holding 10 rounds over the BB magazine’s 6 rounds, the Pellet magazine was still able to get a much tighter grouping at around 1 inch over the BB target which was closer to 3 inches. BB’s seemed to really like to hook a bit with the Crosman Triple Threat CO2 Dual Ammo Revolver, so I would for sure go with pellets if accuracy is importatn to you. Both pellets and BB’s shot a little bit high and to the left from the bulls-eye but that can easily be adjusted with the fully adjustable rear sight.
The Crosman Triple Threat performed rather as expected and was not a big surprise other than the BB’s really having a much lower velocity this time around. It is clear to me that I would not waste my time shooting Steel BB’s unless this is all I had on hand as they where not only much slower but also a lot less accurate. Over time the steel BB’s could damage the rifled steel barrel effecting future pellet accuracy. The Crosman Triple Threat CO2 Dual Ammo Revolver offers a lot of options with ammo choice and barrel choice that alter it’s looks and even performance to some degree but if you want a Crosman 357 type CO2 Revolver than it for sure gives you the most flexibility.
