If you get beaten by people using the same tool, or at least a comparable tool, then i only see 2 options.
1: you are doing it / something wrong, and lord know you can fast mess up your FX rifle if you go for the knobs on it
2: the other guys are just better shots
I am pretty sure many here will shoot the pants off me due to both.
Actually yesterday i tried to shoot a BR50 card,
Setting up my Maverick for the JSB heavy pellets, shooting the fridge i saw pellet on pellet or very damn close, them moving my aim 4-5 feet to the right where the BR 50 paper was,,,,, and OMG i had problems just getting inside the black ring in several shots to the same target, and i had like two 10s and not a single X.
I put like 100 shots into that BR50 paper, ( not counting sighters ) and like 3 of then was ringing my bell ( as in the ballpark of where i aimed ) the rest, well i am / was utterly clueless.
When i return in the weekend i plan to torch that BR50 paper while i dance around it flaying my arms and trying any silly chant / gesture / dance / language i can think off to exorcise the demons in it.
CUZ that one was a big WTF to me,,,, and after that i also ended my session.
BTW my Maverick i can have it dialed in so i hit within 1/4 inch of where i aim, and shoot nice with it, then walk away from the gun and come back 10 minutes later, and now i have to adjust scope again as shots are not landing 1-2 inches away,,,,, though some times the POI will also go back after a handful of shots.
I cant say i have noticed that on my Vulcan 3
I must admit that even if my Maverick shoot A LOT better with the +100 mm longer 700 mm barrel, then the rifle continue to frustrate me, though i do always land at a place where we are in the same ballpark.
It is of course mainly a result of me shooting " a lot" of different things, like right now i am hell bend on getting the "problematic" 16 and 20 gr Zan slugs to fly better than first time i tried those, and i am also seeing some improvements.
