So I got a Diana 34EMS and just mounted a UTG droop correcting base a Vector Optics Veyron 3-12X44 scope and Vortex rings. Everything has been tightened, loc-tightened and allowed to sit overnight for the loc-tight to cure so I went out this morning to zero this new scope. At first, things went going too bad and I was in the final stages of fine tuning my scope when it appears things started to open up with flyers all over the place. This happened with both Crossman Premier 14.3 grain hollow point pellets as well as H&N 18.21 grain Baracuda Hunter pellets.
Now it may be the scope is defective but it’s an air gun rated scope with an etched reticle or it could be my general lack of experience with pellet rifles although I was shooting from a prone position with the forend resting on a sand bag on top of an ammo can a bit loosely to replicate a offhand artillery hold and I’ve been mindful of my follow through after the shot breaks. Could the cold weather here be a factor? It’s about -24 today without the windchill. I know from long range shooting with cartridge rifles, those kind of temperatures can have an effect on a bullets point of impact so I am wondering if using a rifle that has to use this same cold air rather than powder for propulsion may be having problems with these temperatures? Thanks in advance for any suggestions.
