Scope Comparisons

Compare the rifle scopes
The 3.5-10x 50mm SFP doesn’t range as well as the FFP scopes.  The Turrets don’t index multiple turns as well as the FFP scopes.  If you typically use your cartridge with less than 15 MOA elevation, or prefer to Hold-Off, this scope will work well for you at a great price.  The illuminated reticle is a nice option for varmint or hogs in low light.  Pop-up lens covers are included.
The 4-14x 44mm FFP is a high end long distance hunting scope.  It’s dedicated to the challenges of big game hunting at longer distances.  Adjustable parallax ensures the reticle is properly positioned on the target.  If you regularly require more than 15 MOA elevation at distances you need to be sure of, this is the scope for you.  The 4-14x 44mm FFP includes a 4.25″ Sunshade + pop-up lens covers.
The 6-24x 50mm FFP is both a high end long distance hunting scope and a capable bench shooting scope.  24x needs a stable platform to enjoy and it will help you score your target shooting at much longer distances.  50mm objective lens provides a useful FOV at 24x.  The reticle is illuminated for even more capabilities.  The 6-24x 50mm FFP includes a 4.25″ Sunshade + pop-up lens covers.


6-24x 50mm MOA base
  1. The 6-24x 50mm has about 12 MOA of reticle-up adjustment, and 52 MOA of reticle-down adjustment from the reticle being centered.  A 0-15 MOA base will work well with a 100 yd zero.  A 20 MOA base might be a few MOA short of reticle-up adjustment.  A 20 MOA base could be zeroed to 300 yds.
  2. With a 10 MOA base and 100 yd zero, there will be about 46 MOA of reticle-down adjustment remaining.  That corresponds to about 1,100 to 1,200 yds for long distance cartridges.
  3. With a 15 MOA base and 100 yd zero, there will be about 51 MOA of reticle-down adjustment remaining.  That corresponds to about 1,200 to 1,250 yds for long distance cartridges.  15 MOA is likely the optimum base.
  4. With a 20 MOA base and 300 yd zero, there will be about 52 MOA of reticle-down adjustment remaining.  That corresponds to about 1,250 to 1,300 yds for long distance cartridges.  When the reticle is placed on target, it will be 4″ (4 MOA) high at 100 yds, and 5″ (2.4 MOA) high at 200 yds.
  5.  If you prefer MOA adjustment to 1,300 yards with a 20 MOA base, you could hold-under at 100 and 200 yards.  Since 1 mil-dot = 3.43 MOA, 4 MOA is just over 1 mil-dot, and 2.4 MOA is close to 0.75 mil-dot.
Zeroing Discussion
  1. Objective is to coordinate the line of sight through the optic with the ballistic path of the cartridge at the zeroing target range.
  2. Variables are: Environment influenced by temperature, barometric pressure, altitude and humidity;  Cartridge ballistics specified by Ballistic Coefficient (BC) and Muzzle Velocity (MV) plus consistency of those values;  Optic height above the barrel plus any type of inclined optic base;  and to some extent the age and condition of the firearm.  Best to zero your firearm close to the conditions in which you plan to use it.
  3. There is a lot of discussion whether it’s best to zero at 100 or 200 yards. A popular comment is that 200 yards is closer to the usual target range so better to zero at 200 yards.  The range you zero at doesn’t change the bullet path too much.  A 30 Caliber cartridge with a 100 yard zero will be about 13” low at 300 yards vs. 8” low with a 200 yard zero.  You are probably going to make an MOA adjustment at 300 yards either way.  With that in mind, more convenience and precision zeroing at 100 yards seems like the preferred choice.  Most ranges have more 100yd benches and even a 10x scope can locate holes in paper targets at 100 yards.
  4. The basic plan is to get on paper quickly at a short distance, make MOA corrections, and then get on paper at the selected Zero Range. Then make final MOA adjustments and test to confirm optic is zeroed.
  5. One way is to boresight at a long unknown distance so that the optic is nearly horizontal to the barrel. Knowing that, ballistic mathematics can adjust the optic MOA to be near zero at the target range.  This method is diagrammed on the Zeroing Page.
  6. A second way is to bore sight at a short known distance, then do a test shot to measure actual optic position and then make MOA adjustments to be near zero at the target range. If your plan is to zero at 100 yards, you should be about 1” low at 25 yards for 30 caliber cartridges.  See the diagram below.  Only the 0.22 Long is significantly different and rarely used at longer distances.
  7. MOA Adjustments: 1 MOA = 1.047” at 100 yards and is a linear relationship.  So 1 MOA = 0.26” at 25 yards and 2.1” at 200 yards.


FFP Ballistic Calculator
  1. The FFP Ballistic Calculator (FBC) combines ranging via the reticle with Elevation MOA adjustment.  The printout should give you a convenient field reference for fast, accurate target acquisition.
  2. MSFT makes accessing the FBC a multi-step process online.  Use the outside slider to go to the bottom of the page.  Click on the small Full Size workbook icon at the bottom right.  On the next screen, click on edit the workbook.  Next choose to edit online or use your own Excel application.  To edit online you must be logged in to your MSFT account (or create one if necessary.)  If you choose to edit online, MSFT only allows one user at a time even though you cannot save the file back to the original location.  We are working on converting the FBC to run directly in the website to avoid the MSFT issues.  Use Contact US if you need assistance.
  3. If you are not able to download the FBC, send proof of purchase via Contact Us and we will email you the FBC.  It even runs on smart devices that have the Excel app.
  4. The FBC is target size specific so you will need to print a chart for each target size.  Typical target sizes for Elk, Deer, Antelope, etc. are listed in the FBC.
  5. Remember that MOA adjustment is influenced by environment factors such as temperature and altitude, firearm factors such as scope height and zero range, and ballistic factors such as BC and MV.  Be sure to list them correctly in the FBC.
  6. For improved accuracy, you can manually list your actual MOA for known ranges.
  7. You can adjust the MV (fps) and BC to see if you can better match the FBC results with  your target practice results.  Typically, manufacturer’s MV are a little (~2%) high so it’s suggested you try MV adjustment first.
Hold-off vs. MOA Adjustment
  1. MOA adjustment is suggested for longer distances and when you have time to make the adjustment.
  2. Hold-offs are useful for shorter distances or when there isn’t time to make an MOA adjustment.
  3. 1 Mil-dot is 3.43 MOA.  3.43 MOA corresponds to the bullet drop at about 275 yards with a 100 yd zero.  The bullet drop for 2 Mil-dots corresponds to about 400 yds and 3 Mil-dots corresponds to about 500 yds.
  4. At more than 500 yards, accuracy becomes very important and it is probably best to use the precision of MOA Adjustment instead of Mil-dot Hold-off.  For instance, +/-0.2 Mil-Dots accuracy is more than +/-3.5″ at 500 yards and of course increases at longer ranges.
