No one can help you if you don't provide specifics. I will say though if it's truly shooting 25MOA I doubt it's anything component related.
You got me! Your a "Daisey" if ya do.Not sure if the twist rate. 18" barrel. I think I need to feed it better ammo.
I believe a trigger job a little bedding and possably better BB will get you there crossman builds a better BB than DaiseyRifle weighs 2.4 lb but has 4.5 lb. Pull according to my scale.
Seriously, ya had me !Not sure if the twist rate. 18" barrel. I think I need to feed it better ammo.
Try lightly oiling the barrel, fire or few rounds to clear the oil out then shoot a group.
Have you tried using sandbags or a lead sled or anything to help the rifle stay steady?
Also your rear site may be bouncing around between shots those wedge styles sites arn't very secure.
Can it accommodate lead pellet?
