In this Filed Test Shooting Video recorded in the Replica Airguns Indoor Sea Can Shooting Range, I test out the GAMO P-27 NBB CO2 Dual Ammo Pistol to find out what the actual velocity is in fps shooting both 4.5mm steel BB’s and .177 caliber lead Pellets. I also put a full side of each magazine into a paper target setup 30 feet down range again using both BB’s and Pellets to see which ammo type may be more accurate out of the GAMO P-27 NBB CO2 Dual Ammo Pistol? If you are more interested in details and specifications along with some closer up video of the GAMO P-27 then make sure to watch my Table Top Video for it.
Let’s get right to the velocity test of the GAMO P-27 NBB CO2 Dual Ammo Shooting 4.5mm Pistol. Gamo does claim up to 430 fps, I am not sure if this is for BB’s or Pellets or maybe even light weight alloy Pellets. In any case I used standard 4.5mm 5.1 grain steel BB’s and around 7 grain lead Pellets for this test. Shooting 3 rounds of 4.5mm steel BB’s through my Chronograph I averaged 342 fps with the three shots recording 349, 342, 334 fps. Switching to lead Pellets I averaged 288 fps with the three recorded shots of 290, 291, 282. The 4.5mm steel BB’s as you can see shot faster than the lead Pellets but this was most likely due to the heavier weight of the lead pellets.
I was interested to find out if the .177 caliber Pellets where going to be more accurate in the GAMO P-27 NBB CO2 Dual Ammo Pistol as pellets traditionally are more accurate than BB’s but in the case of the GAMO P-27 the barrel is not rifled so there may be less of a benefit shooting pellets for accuracy purposes? The best way to find out is to try it out so that’s exactly what I did. Again starting with 4.5mm steel BB’s I place one side of the 16 round magazine, so 8 rounds into a fresh pepper target setup 30 feet away. I did use my standard shooting stance of sitting in the back on a stool and placing my hands on a sand bag up front for some stability. I did notice the GAMO P-27 NBB CO2 Dual Ammo Pistol liked to shoot a bit high and to the left but I did get around a 3.5 inch grouping and if I removed two shots that where on the outside of the grouping I would have had closer to a 2 inch grouping. Switching to the .177 caliber Pellet side of the magazine I then was able to get my 8 rounds a bit tighter hitting around a 1.5 inch grouping with most of the shots all within 1 inch of each other. Pellets at least for me where the better choice in terms of accuracy.
The GAMO P-27 NBB CO2 Dual Ammo Pistol is a fun little BB and Pellet plinker capable of plinking and action shooting at closer up ranges. I would not want to shoot out much further than 30-40 feet or so but it is accurate enough especially with Pellets to hit pop can sized objects at those ranges. I do like that you have the option of shooting both single and double action as the GAMO P-27 NBB CO2 Dual Ammo Pistol does have an actual working hammer and this does lighten up the trigger a bit more for accurate shot placement when shooting in single action. If a fairly affordable NBB dual Ammo Airgun is what you are after than consider grabbing yourself one over at of one of our Replica Airgun Online Stores, Canada or the US.
