Thread: Scope issues?

Does anyone know where to get a scope checked out?
Have a weird issue with one of my rifles. Used to shoot like a lazer but lately it's been doing weird shit.
300 winmag suppressed with a Bushnell 6500 2.5-16 x 42 scope. Used it to nail two deer on a rainy weekend, took it out of the stock for a bit to let everything dry out put it all back together and checked it was still shooting staright. Last time I took it for a hunt I missed 2 easy shots around 300m.
Checked the rifle and found it to be shooting way high. checked all action screws, mounts, rings etc. Resighted in and back in the safe.
Last two times I've taken it out to check zero's have been last weekend and about 6 months before that. Both times it's been way off
Zero it back in after giving it a snake and cool down then check again and it's not quite right. Basically go through a pack of ammo to get back to the original zero.
Last time was the same.
Other rifles are shooting bang on so it shouldn't be my shooting. The springs on the turrets seem piss weak and I have a suspicion it's something funny going on in the scope.
Any one have any idea's ? I don't really want to swap scopes as the only other one with a 30 mm tube lives on my 30 06 and I don't want to split that combo.
