Elevation too high for 25m zero

[samirkilachand]

Hi,



I have an FX Crown .30 with 600mm barrel. It’s shooting 44.75g at 850fps. I put in a Viper PST Gen 2 5-25x50 with Warne 216L extra high mounts. 


I tried to zero the scope at 30m and it needed 39 MoA of elevation. Is that normal? The dial doesn’t have very much more elevation adjustment.

It’s likely the extra high mounts . Good place to use FX no limit rings

Yes, the adjustable mounts or shim the rear mount. Cut out two pieces of business card thick material. Install on the rear mount between the scope and mount. That should give you about 20 MOA. Easy day... and yes, that is normal with the high mounts.

If I have to shim (which I don't like to do) I will usually use a soda can and cut out a rectangle that will fit the bottom of the mount saddle on the rings. Two pieces, at the most 3 should do the trick. Don't really like to do that though, scope tubes can be fragile if torqued down on a surface not very close to being absolutely level. In the end, I will usually go with the FX or SM adjustable mounts.

One place where it didn't matter at all was when I shimmed my Impact (1st Gen), put the shims under the raised pic rail. No stress on the scope whatsoever.

I don't shim scopes either but many seem to have it work well. I'd suggest being careful with torque on the top strap screws if shimming for the exact reasons mentioned. I use SM rings on several rifles and they work great. No experience with FX but many like them as well.

I'm with CC, Buy no limit rings. I shimmed a scope once using the tin can method and it worked but I still couldn't get the range I wanted. No limit rings fixed that, Plus if you want to stretch out to 150+ you will most likely need them anyway.

Good Luck!

Thanks a lot guys. I’m gonna get the FX no limit mounts. I’m new to serious airgunning and I’m loving the technical aspect of it. 


I don’t know how I would have sorted out all my issues without all of you on this forum



bit by bit it’s coming together. Can’t wait to stretch it out. Where I am we can’t have firearms so this is all I have. No regrets either - definitely more backyard and hearing friendly.

FX No limit or Sportsmatch fully adjustable will either one do the trick. The Sportsmatch are easier to adjust in more precise increments but I have used both with much success. Either one will solve your problem.

Hey folks,

So I got the fx no limits mounts and cranked the rear up enough so that I have 40 MoA left to dial up on the turret plus the reticle gives me another 32 MoA. StrelokPro tells me that’s enough for 200m if I can do my part.

Thanks for the assistance everyone!
