got a 300s and a hawke sidewinder 4-16. Have zeroing issues.

[bruceruth1988]

I have the scope mounted in a BLK-354 mount. I can get the windage adjusted but it is shooting 4.5 inches LOW at 10 yards. That equates to 45 minutes of angle. The scope, and I doubt any scope, will not adjust that much. SOOOO, how can I make this work?

If I calculated correctly I am looking at a .040 shim. That is huge I think.

Looking for suggestions.

Thanks

That's totally normal to have droop even with fixed barrel springers and SSPs unless you run a really low magnification scope with lots of elevation. You can buy the UTG Picatinny droop base to do what you need.

Modify FILE the stop to fit in the groove to avoid creep.

I cannot in good conscience recommend the BKL brand due to recent post having issues.

You can try the cheapie RWS Lockdown mount too but not sure if you will have to DREMEL IT (DREMEL WORKS!) a little to clear that HAWK belly. Mod the stop pin to fit the 300 groove.

Check for 15% discount if it still works there.

Man this is cheap!!! I paid $30 for mine!!!

 

[bruceruth1988]

thanks but that is not going to help. It mounts the scope WAY to far back. Has to look like the attached pic with the eye piece even with the back of the action.

If you go with the UTG dropped Picatinny then get the Burris Signature XTR rings with the shim inserts inserts to perfectly optically center your scope that won't put a mark. $70.99 THIS IS CHEAP! These usually sell for $99.95 and often well over $100 from dealers.

Here's someone selling shoot an offer with the $70.99 price reference.

Mount both rings only on the rear section of your scope tube or just buy the 0.007 droop compensated version of that BKL Or send yours to MAC1 to machine the droop in that mount you have.

You can also bend your barrel up too it's real simple. No need to change anything. Accuracy should still be the same. The best airgun tuner in the world bends barrels FYI.

 

[bruceruth1988]

dont think I will be bending my barrel. Dont have the tools or knowledge.

How bout the FX no limit rings

 

[bruceruth1988]

is .007 even enough??

50 minutes of angle or 50 inches at 100 yards.

the rings are 4 inches apart.

100 yards is 3600 inches.

so if we are talking 1 inch at 100 yards or 3600 inches that would be 1/3600=x/4 so x = .0011 for one minute of angle. ,0011x50=.055 for the shim or droop compensation.

Somebody please check my math.

JUST To get an idea what some do. If you lived close I could offer 5 seconds of my time and my right knee and 2 arms and no fixture needed then done. No more droop. Seriously that simple.

FX might not clamp down firmly enough to avoid scope creep compared to BKLs but you would mount both against each other on the rear tube and need a scope stop.

Here's my setup. First, get a UTG 11mm to picatinny drooper rail adapter from Pyramyd:

https://www.pyramydair.com/s/a/UTG_Drooper_Scope_Rail_11mm_to_Weaver_Adapter_Compensates_for_Droop_Stops_Scope_Shift/4191

Then, any Picatinny/Weaver rings should work ok. Don't be afraid of the scope height. This will give you enough clearance to insert the pellets into the barrel. I use this for 25 M BR shooting and it works well. I'm of the firm belief that the barrels don't droop and are straight with the receiver. It's just that the pellet trajectory is so loopy that you need to adjust the scope angle to match. "Drooper" mounts are used on firearms too, especially 22 rimfires.
