Well I learned the hard way, I owned a PCP about 15 years ago. Like I said shortest love afair with any gun I ever owned!
In fact your exactly right, this 54 Diana is down right boring! Ive lost about 4fps the last 100 pellets, so I think with consistent Extreme Spreads holdin in the single digits, I think I got it broke in the past 5 days. The sweet thing is I aint had to stop and fill it once, just cock and load, about 500 shots thru it now.
The new Airmax 30 4-16x50 SA FS IR came this morning, and 3 shots and was on target at 25 yards, just right, so shot 4, 5 shot groups, all low 2's. Then with the AA Heavy Field Diablos it took another 3 or 4 shots to get it dead on. This is a great scope, bright and crisp as you can get. @ 25 yards both AA and Heavy Diablo JSB Exacts will group under .2" @ 25 yards. If I shoot 5 of each at the same poa, it gives me a .3" 10 shot group. The AA's are 18.0 grains, the JSB's are 18.1 grain. and 740.0 fps w/ES 9,3 and 738.7 fps w/9.4 respectively. QUITE HAPPY!
Best thing is, as boring as it is to get same hole groups, with 5/4 board full penetration at 25 yards, I'm still showing full on my first tank of air,,,,,,,
