200yrd zero on a 50yrd range? Savage Axis II in 243

[Corpral_Agarn]

Can it be done?

Buddy of mine has a Savage Axis II in a nice Boyd's laminate stock chambered in 243.

He asked me to sight it in while he is gone. I agreed (of course!).

My home range is 40-50yrds long. I can get a longer range if I need it, but that's what I have within walking distance of my house.

I don't know much about the 243 cartridge and what distances match others (say a 223 50yrd zero is real close to 200yrd zero) so I am looking for some data on what kind of offset I should be using to achieve a 200yrd zero with the rig.

Once I get it real close at 50yrds, I feel like hitting the 200yrd range is a more value add activity.

Any tips on sighting in the Axis II, info on Boyds laminate stocks, info on 243 cartridge would be appreciated!

Thanks!

Either find the specific bullet in question from the drop-down menu, or get the relevant data from the manufacturer's website. Find an approximation of the muzzle velocity for the chosen cartridge. Plug in all the other data including your desired zero and sight height above bore axis.

It will spit out a bunch of info, including height above or below POA at all distances and increments you have chosen. So make one of those your know target distance. Zero the rifle for that height above (most likely) your POA at the known range. That should get it pretty close.

If you're zeroed at 50 yards you'll be pretty close at 200. Certainly close enough to be on paper and then fine tune from there. Most center fire cartridges with a 100 yard zero will be about 1/2" low at 50. But there is no way to get it perfect until you actually shoot at 200. There are so many variables that can't be controlled.

Ballistic AE has both the Winchester 100 gr Power Point and Federal 100 gr Soft Point .61" high at 50 when zeroed at 200. This is with sight height at 1.5".

Jmr40, my 243 zeroed at 100y then shot at 50y out of curiosity on poi. Your right, does hit 1/2" low at 50y

Thank you all very much!

Hope to get this out and on the range this week.

Appreciate the info!

let us know what you think....that is on a short list for me....recoil and screws holding your head on don't go together too well.
