Tried the .177 PCP versaion (Varmint) for a comparsion against the co2 version (Plinker) with and without magazines.
Same pellets, just going a lot faster and earning 2 1/2 times more energy from the PCP version.
Rifles: (and they do make a "matched pair". one for plinking and one for serious):
Co2(plinker): (to keep things "even" with gas use, Mag #1 never made it to the shoot-off):
I'm looking at Mag #2 as the "spoiler". Really way too short a test to be sure, but if I take out Mag #2 as being "off", the single shot/ mag. fed accuracy is prtty darned clase to equal (within 1/50th of an inch).
So I will measure and test mag. #2 to see what (if anything) is really different about it freom it's mates. Absolute worse case, I toss it to the back of the parts-box. Best case, I fix it. Anything in the middle will just keep me guessing.
