Cali_Ed Posted July 7, 2014 Report Share Posted July 7, 2014 Not sure if I'm in the right section guys, but after my 100 yard zero do I just increase the magnification to increase the yardage? Or what's the proper way of let's say shoot up to 600 yards. Do I use the hash marks on reticle? Or will i still need to mess with the turrets? First time with a scoped rifle so I apologize for all these questions Quote Link to comment Share on other sites More sharing options...
LAR8Autoshucker Posted July 7, 2014 Report Share Posted July 7, 2014 Adjusting zoom wont or at least shouldn't effect bullet impact at all. As far as how to use the reticle marks, and turret consult your owners manual. It all depends on what type of scope it is. Quote Link to comment Share on other sites More sharing options...
Cali_Ed Posted July 7, 2014 Author Report Share Posted July 7, 2014 I know each mark indicates 100 yards, I was just wondering about the longer range shooting. I'm assuming I zoom up shoot and them adjust then return to zero when done? Quote Link to comment Share on other sites More sharing options...

Cali_Ed Posted July 7, 2014 Author Report Share Posted July 7, 2014 I'll have to double check the manual. Vortex viper mil dot 6.5-20x44 Quote Link to comment Share on other sites More sharing options...
FaRKle! Posted July 7, 2014 Report Share Posted July 7, 2014 You'll either have to use hold overs or dial your elevation (after calculating your bullet drop per distance). Quote Link to comment Share on other sites More sharing options...
Cali_Ed Posted July 7, 2014 Author Report Share Posted July 7, 2014 (edited) Reading the manual kinda blows me away, I definitely need to get a note pad for my range calculations and the ballistic charts for my ammo haha holy moly Edited July 7, 2014 by Cali_Ed Quote Link to comment Share on other sites More sharing options...
blue109 Posted July 7, 2014 Report Share Posted July 7, 2014 (edited) unless your scope is FFP, the subtensions in the reticle will equal different measurements at different levels of magnification. the distance from one line to another at 10x is not the same at 20x. your reticle will only be accurate (1dot section = 1 mil) at a specified power. any other magnification level and you need to do the math. there are some handy ballistic calculaters you can download for free. they do all the work for you and can tell you how many clicks to adjust or how far to hold. I have one called strelok that is fun to play with. Edited July 7, 2014 by blue109 Quote Link to comment Share on other sites More sharing options...
bubbasks Posted July 7, 2014 Report Share Posted July 7, 2014 Go to app store. Buy Shooter and GPS Status. I love both. Btw gps status I use for basic nav and pitch angles (both perty dang close) Quote Link to comment Share on other sites More sharing options...
pokey Posted July 7, 2014 Report Share Posted July 7, 2014 There is a web site you should visit, it's called rex reviews or tiborasaurus rex. The site talks about rifles, techniques, and optics. It's like crack to a long range rifle junkie. It is great watching, being a you tube channel. Quote Link to comment Share on other sites More sharing options...
Cali_Ed Posted July 7, 2014 Author Report Share Posted July 7, 2014 (edited) You know what i I started to watch a Video with that guy but it was to long, I know he suggest going by meters and not yards Edited July 7, 2014 by Cali_Ed Quote Link to comment Share on other sites More sharing options...

shibiwan Posted July 8, 2014 Report Share Posted July 8, 2014 (edited) Ed, Use the LRBC app on the vortex website. http://www.vortexoptics.com/content/lrbc If you are having problems figuring out what data to put where, let me know and I can input the data for you and generate the PDF's of the reticle at dfferent magnifications. Looked it up and figured out that the mil-dot reticle is calibrated for 14x on your SFP scope. Here is the reticle chart in MILS (mrad reticle) for FGMM 308 175gr SMK HPBT (see attached PDF). Your reticle at 14x is "similar" and the mil dots match up to the major MIL hash marks (i.e. 1, 2, 3, 4) on the mrad reticle. You'll also notice that the following image (right) is pretty close to the reticle chart, since the image is set up for 168gr projecticles. 14xVortex Optics - LRBC.pdf Edited July 8, 2014 by shibiwan Quote Link to comment Share on other sites More sharing options...
Cali_Ed Posted July 8, 2014 Author Report Share Posted July 8, 2014 So on the first image the center where both horizontal and vertical lines meet is 100. Then on the next major hash marks it's jumps up by 285 yards to end up at 385? So then its not a consistent increase using the hash marks because then it jumps up by 185 to end up at 570 or am I looking at this wrong?

blue109 Posted July 8, 2014 Report Share Posted July 8, 2014 the bullet doesn't make a perfect arc...and each round will have different characteristics. a hot loaded 150 isn't going to hit anywhere near a subsonic 175. there isn't any simple answer here. you need to either cheat like I do and get a ballistics program, or you need to spend a few days/Weeks on the net reading up on all this. I've done enough reading to have a general idea how it works, but I don't have the time or resources to practice the art so I just plug numbers into my app and it tells me how many clicks to dial up. if your setup/ammo is consistent you can make a little cheat sheet.

So then its not a consistent increase using the hash marks because then it jumps up by 185 to end up at 570 or am I looking at this wrong? It is not a consistent increase since the bullet's trajectory is parabolic (curved) the deviation/drop from the zeroed point at 100 yards increases exponentially for each incremental distance. The MIL reticle has a uniform hash marking. This is primarily for range estimation, and coupled with the right bullet drop chart, makes it universal, from a caliber/load standpoint. You'll notice caliber-specific BDC reticles have an exponential reticle. The holdovers are spaced out farther for longer ranges. e.g. Nikon M308 e.g Safariland BDC 800 reticle e.g. Bushnell BDC/DOA reticle Quote Link to comment Share on other sites More sharing options...
survivalshop Posted July 8, 2014 Report Share Posted July 8, 2014 I think you are better off not paying too much attention the the MilDots & use your Turrets for adj. for adding to or subtracting for range . If you sight in at 100 yards , thats your zero on the turrets & how many clicks for windage or elevation , at different ranges is what I use ,Once I set my zero , for example , mine are set at 100 yards , I have with a 168gr. load , its three clicks up & two clicks left for me to center @ two hundred yards , from my 100 yard zero. I Make notes or a dope chart for what bullet weight or load I use & I can always go to the notes to go to the right amount of clicks for them . Some tape these to there rifles for easy viewing . As said above , the MilDots or hash marks or BDC are just reference & will most likely never match up to different loads you are using . They are also as said for range estimation or quick shooting , Kentucky windage /elevation. Quote Link to comment Share on other sites More sharing options...
