I'll definitely try different ammo, thanks.
In the meantime, for the cost of an entry-level scope, I think I'll replace the one I have now anyway.

Also, I don't like the clutters reticle much.
Based on Edinburgh Rifles' recommendation, I think I'd give Wulf a go. They come with lifetime warranty, and while the Vortex warranty is probably superior, for the price I could buy another scope... and, the Wulf is the lighter of the two.

Any advise please?
