Tuning Red Wolf HP .25 tuning

[ausvette]

I have a Red Wolf HP .25 and I'm after some tuning advice.

On high power its shooting:

JSB Exact King .25 Diablo 25.39 gr pellets at 919 fps .

JSB Exact King Heavy Diablo MK II 33.95 gr pellets at 805 fps.

It seems a little more accurate with the 33.95 gr pellets which surprised me. I thought the 25.39 would be more accurate?

What fps should I be aiming for with the 25.39 and 25.39 pellets?

Would the 25.39 be more accurate on medium power at a lower fps?

On my safari .25 I shoot the 25.39 pellets on low power at around 860 FPS. MOA at 100 yards if I do my part. If I speed them up they loose a little accuracy. The 33 gr on medium power at 860-870 are just as good, again, faster not as good.

Om my sarafi .25 cal shoots 34 gr on high at 995 fps and 885 fps on medium with good accuracy for both (but better on high : 0,9 MOA at 103 m / 112 yards at 8 mph wind)

For 25 gr it shoots at 915 fps with good accuracy.

You want to aim for 880-ish for the best LONG RANGE accuraccy, at closer distances the higher velocities are okay but will open up at 75-100 yards.

You high power curve seems very low velocity at 805 FPS with the 34g JSB? how old is the gun?

Its 2 years old but for various reasons hasn't been used much for the last year. Maybe I should get it serviced?
