Actually, I have a few rifles with scopes. Some are simple, with just a basic cross hairs, the others with the more complex settings. Truth is, I don't know anything about them beyond just setting the cross hairs on the target and trying to hit it.
I'd like to be able to use them successfully, how to range, adjust settings, etc. What do I need to know? TIA |

Fist step is to know if your reticles are moa or mrad. The scope's turrets should be marked as such.

Someone gave me a 'manual' range finder that I think is MRAD (I haven't looked in a while) ranging monocular. Scopes: A Leopold Rifleman 3 X 9 X 50 on a 24 inch Varmiter, and a Vertex Crossfire 4 X 12 X 44 on a Remington 700. Both are 223/556. A couple of others but buried away somewhere. |

As I said, if you look at the windage and elevation turrets, it should tell you which type you have. Post pics of the turret if you aren't sure. There are different procedures for your questions depending on what kind of reticle you have. Kinda like asking how to take apart your pistol. Well what kind of pistol is it? Can't answer without that info. |

Neither of those scopes will help you learn to range with their duplex reticles. You will need either an MOA or Mil based reticle to range but honestly it's a dying art and if you have a LRF then use that. It's faster and much more accurate. If you did want to try it then you need a different scope. Not sure what manual rangefinder you have but stick to lasers. |

Say I range a target at 337 yards with the LRF. How do I use that with a scope? I see videos of guys spinning away with the turrets/setting but what does that do? |

OP, you need info on your loads(ammo) and how specifically it shoots in your rifle..you then pick a target, range it(as in the above example we will go with 337 yards) you then go to here or another program and figure out your dope(the correct adjustments for your scope, on your rifle, with your ammo) and then you dial the elevation and windage as provided by your dope, then you shoot..if everything is right, you should get center of target hits....
https://www.jbmballistics.com/ballistics/calculators/calculators.shtml This is what your dope should look like, it has distance, it has the adjustments for windage and elevation in either MOA or MIL depending on your scopes needs, and it tells you velocity and energy at your measured distance.. This is for one of my rifle/loads...  Attached FileETA: OP, I highly, highly recommend you spend a few dollars on this book, it will explain the whole process of long range shooting from start to finish for you in easy to understand terms....

I see videos of guys spinning away with the turrets/setting but what does that do? As posted above you get your velocity and bullet along with your environmental data and rifle data and put them into the ballistic program and it will give you data. Run it in either MOA or Mils depending on what your scope adjusts in. I will say JBM works great but use the Simplified version I linked below. It allows you to input the stuff you need and nothing to confuse a newer shooter. I use the Simplified when I get data from JBM for matches for just shooting. The only two boxes you leave at 0 are Line of Sight and Cant Angle. Everything else you put in data but Target Speed may be another as not a lot of people shooting movers. https://www.jbmballistics.com/cgi-bin/jbmtraj_simp-5.1.cgi Sight height is one of the things people have problems with but it's simple. Use a ruler and measure from center of bolt to center of windage knob and input height. Simple as that.

I zero .223 high power rifles at 200 yards. At any range up to around 230 yards I am never more than 2" high or low of the aiming point.
At 300 yards I need to hold 7.5" high or dial 2.5 moa of elevation. Ammo selection dependent. You really need to get shooting to establish your zeroes. Changing ammunition will change your point of impact. |
