In this Field Test Shooting Video I run the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol through its paces to find out how much power and accuracy we can expect with both 4.5mm Steel BB’s and .177 Caliber Lead Pellets. If you have not yet watched my Table Top Video for the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol, then make sure to do so for information about details and specifications along with some additional photos.
As always I placed a brand new C02 in the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol to get maximum power and the temperature was around 21 degrees Celsius or about 70 degrees Fahrenheit which is warm enough to get good velocity results but not hot enough for maximum fps so keep that in mond. I deiced to shoot 4 Steel BB’s, and 4 Lead Pellets through my chronograph and averaged the velocities out for each ammo type. The Steel BB’s weigh about 5.1 grain while the Lead Pellets weigh a bit over 7 grain so I was expecting to see higher numbers with the BB’s which is exactly what I got but not near as high as the claimed 495 fps.
My actual velocity result for Lead Pellets was a 4 shot average of 332 fps with the slowest being 313 and the fastest shot hitting 359. For steel BB’s I was able to average 346 fps so not a lot faster at the end of the day but close. My slowest Steel BB Chronograph reading was 342 with the fastest shot at 356 which was actually just a bit slower than the Lead Pellet fastest velocity reading. Lead Pellets tend to seal in the barrel better than Steel BB’s so even though they are a bit heavier they still get pretty close velocity readings to BB’s since the less CO2 blows by the ammo with Lead Pellets.
Sine the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol has a double sided rotary magazine that holds 8 rounds on each end, I loaded one side with BB’s and one side with Pellets and proceeded to see how tight of a grouping each ammo type was capable of with 8 rounds. As expected again the Lead Pellets performed better getting about a 1.5 inch grouping well centered up a down on the bullseye but a tad to the left of it. The Steel BB’s did spread out somewhat getting closer to a 4 inch grouping that this time was better centered side to side but a little bit low of the Bullseye. Out of the box the sights seem to be fairly well centered which is nice since they are not adjustable.
So the Gamo P-430 CO2 Dual Ammo BB Pellet Pistol isn’t the flashiest Replica Airgun out there, maybe not the most powerful or accurate Airgun either but it is fun to shoot and does offer more options in terms of ammo choices when shooting. Velocity is really close between Steel BB’s and Lead Pellets and since the Lead Pellets are about 2 grain heavier they will have more energy downrange when they hit a target. The Lead Pellets also performed better in the accuracy department and shot a respectable 1.5 inch 8 shot grouping so if this was my Airgun I would probably go with Lead Pellets as long as I had some on hand, but if all you have around is Steel BB’s than at least you can keep on shooting which is what it’s really about at the end of the day.
