Until you get a new scope, cheat with the one you have.
1. just find an accurate load with the a good 140 and stick with it.
2. Set the gun up to shoot 2" at 100. That should put you about right on at 250 or so.
3. Email redfield and ask for the dimensions of the crosshair and duplex top and bottom for your model scope. Or you can use a yardstick at 100 to measure exactly the distance between the cross hair and the pointy top of the bottom duplex. I am guessing somewhere around 6-9" at 9x. Once you know that distance, and what load you are using, someone with a ballistics program can get you pretty close to where your POI will be at the top of the bottom duplex.
4. That should give you bullet path distances to somewhere around 450-550 yards or so with a 7 rem mag and 140s at 3000 fps. Practice with some paper targets at distances will quickly confirm your exact drops. Put them on piece of tape on side of scope and practice on some water filled milk jugs at distances will quickly give you some confidence.
Where in MO are you? Grew up in Brunswick and deer hunt there 10 days every year.
Welcome aboard!Find out how fast you are running which ever bullet you decide on and email me I will run it on some of my ballistics programs not saying they are accurate but work pretty good for me. [img]/ubbthreads/images/graemlins/wink.gif[/img]
Well, there was some Federal Premium 150 Grain Solid Bases something's on sale for $9 a box. Vital Shock stuff is usually much more so I got 3 boxes, should keep me busy. The cheapo Core-Lokts shot under an inch at 100, I'm hoping the Federal's do 3/4" or better since I got 3 boxes. If they are real accurate I might not even mess with handloads loads for deer this year, everything is real busy going into highschool. I think it's 150 grain going at 3100 or 3150 fps.
The other thing you need to do is practice you range estimation techniques. A range finder is a luxury not a neccesity for distances to about 500yds. After that things get a little tricky.
Go to a football field and pace off several times a hundred yards walking "normally". I count on a right foot step and my pace stays right at 55 per hundred yards. I use this information for bowhunting a lot. Uphill is different and going around sleeping skunks will also affect your pace count.
Once you know your pace and have memorized what a hundred yards looks like, then you are ready to practice.
Practice is best done when you are just goofing around. Find an object that is out there at a good distance and estimate where each hundred yard increment will be and what the final range to the object is and then start pacing and counting to see how close your eyeball estimate is. With practice you can get very very accurate to about 300 yds and then eyeball accuracy will degrade. Hardest to estimate is over open air. When you are on a ridge and the object is on another ridge you have no visual clues such as size of a tree or rock to get your increments estimated correctly. Without being able to count off each separate hundred yards to an object the final estimate will be significantly off.
By following Bounty Hunters advice you may be able to use your duplex reticle for range finding but we can discuss that technique once you do the measurement.
I am in total agreement with BH, and BB on this. That plex reticle u have there is one of the best entry level ballistic and rangefinding reticles going, and will get u to intermediate ranges just as effectively as any ballistic reticle out there really. These days if you're 14 y.o. u probably have more math knowledge than most on this board (especially me). Once u find out what that reticle subtension measurement is (that BH mentioned) u can easily apply a "tactical-type" system with it for downrange trajectory (both elevation and windage) and rangefinding, by applying simple mathematical formulas, and ballistic programs. Once u learn to apply these systems in the field it will blow your mind (and your buddy's) watching 500 yd. milk jugs blow up with a good degree of consistency from the 1st shot on, believe me. IMO, intermediate-range shooting (beyond point blank range), is more relearning optics applications than anything else. Get out to that 550 yd. range close to your grandfather-- in a way that'll become your research laboratory.
Here's a link to a system that should help u some--
This forum is a great place to further your knowledge-base on this topic. A world of info at your finger tips--literally.
Oh yeah, and when u ask people for help on shooting-related matters, tactfully slip in how old u r (just like u did here)-- most shooters r pushovers when it comes to helping kids get started in their favorite pasttime.
What brand is the 150g bullet you are pushing 3100 fps? You can take much guess work out of shooting with where you have your zero especially with a flat shooting rifle... [img]/ubbthreads/images/graemlins/wink.gif[/img]
Tyler, Im 20 and started reloading and getting into longer range shooting right around 14-15. I started with a 25-06 and a 3-9 leupold. I practiced on milk jugs at 300 yards. When I got good, consistently hitting them, I moved out to 400, etc. Now I practice at 500 and 800 pretty regularly. Its great to see youngsters get into this sport. I am glad I did. I have learned so much great information from a lot of great shooters. The best thing about this place is that were all interested in the same thing, long range shooting. That means no one will put you down for taking a long shot if you think you have the confidence to do so. Anywhere else on the internet you speak of shooting past 300 yards, your going to have an all out war. Just remember knowledge is power and the more you know about this sport, the farther you want to shoot.
