Cooper 52/Swarovski Z5 issues. NEED HELP!!!!

[20VarTarg]

I recently purchased a Swarovski Z5 3.5-18 with the Ballistic Turret. I have mounted the scope on my Cooper Model 52 chambered in 338 Win Mag. I have zeroed the scope at 100 yards and have shot it out to 300 yds using the BT. I punched in all my load numbers in the Swarovski Ballistic Calculator and set the BT. My problem is I run out of elevation at 400 yards. I would really like to have clicks out to a minimum of 600 yards. How can I correct this issue?? It's a 2 piece Warne Mount if that matters. Scope is in a set of Warne Med Rings. There is about 3/8" between scope objective and barrel so I think I could possibly put it in a set of low rings. But not positive that will help my situation at all.

I put a one piece 20 moa base on my model 52. Then use the signature rings with synthetic inserts. The 20 moa base should help you be able to use more of your scope’s adjustments.

Hey Gary, was it a Ken Farrell base or does someone else make a base for the Model 52. I saw the price and almost died.

I think it is one of his. I’d have to pull the rifle out to check. Yea, they aren’t cheap.
But I’m pretty sure that there were others, I’m not sure where I saw them, one of the online places - Midsouth , Midway, etc.
