Shooting Positions in the Field :: NSSF Ryan Cleckner




I have only shot from a few positions while hunting. While sitting in a tree stand, sitting in the snow with a bipod, knelling in a corn field and standing during a drive. I've had varying degrees of success with each position which is why it's important to practice them.

What do the Numbers mean on a Magnified Optic?


The numbers we see on a magnified optic; whether it is variable or fixed, are the specifications of magnification and size of the objective lens. For example:

3-9x40mm

With the numbers listed above we know that the optic is a variable power scope that offers a three times normal magnification at its lowest setting and nine times normal magnification at its highest setting but can also be viewed anywhere in between.
The 'forty' at the end is giving the measurement of the diameter of the objective lens in millimeters (mm). This holds true with any set of numbers:

2-7x32mm
4-12x42mm
5-20x50mm

When you have a fixed power optic you will only be able to view a single magnification. The numbers will give you the magnification first followed by the diameter of the objective lens (like above on variable optics) for example:

2.5x32mm
4x38mm
5x40mm

Now when you are optic shopping you will be able to understand what that jumble of numbers and letters mean and make an informed decision

.38 Special Ammunition Recoil Comparison :: Ruger LCR and S&W 637


When you begin carrying a firearm one of the most important decisions you will have to make is what type of defensive ammunition to use. There are many factors that come into play during this decision; manufacture, consistency, reliability, performance, cost and type are a few qualifiers. One aspect often over looked is controllability. Whenever we press the trigger and fire a round there will be recoil. There are actions we can take to mitigate this recoil including grip and stance but also includes your choice of ammunition.

The Guns
I wanted to see what kind of recoil was developed from a couple popular carry revolvers chambered in .38 Special. The Ruger LCR and Smith & Wesson 637 are both staples in the world of concealed carry. How would they perform firing some of the most popular defensive loads?

The Ammunition
I gathered five loads that were locally available. LuckyGunner.com sent me a sixth load, MAGTECH First Defense; that was not available to me locally. The ammunition I fired was:
  1. Blazer Brass 125gr. .38 Special FMJ (Control)
  2. Winchester PDX1 130gr. .38 Special +P BJHP
  3. Remington HD 125gr. .38 Special +P BJHP
  4. MAGTECH First Defense 95gr. .38 Special +P SCHP
  5. Federal Hydra-Shok 129gr. .38 Special +P JHP
  6. Hornady Critical Defense 110gr. .38 Special FTX
The Test
I drew 1/2 Inch grid squares on a poster board to help find the exact point of muzzle rise after a shot was fired. I setup two tripods; one with a camera and the other functioned as a rest to ensure the pistol was placed in the same position after each shot. I fired the ammunition, in the order above, in hopes of being able to discern a difference in recoil once I slowed down the footage.


While firing I was not immediately able to descern a difference from load to load but the camera saw a difference.

The Results
Each load had a comparable amount of recoil in each revolver. The biggest surprise for me was that one load displayed a lower recoil than all of the others. It happened to be the MAGTECH First Defense load that LuckyGunner.com sent me.

Was my test super-duper scientific? No. I wanted to see which personal defense load recoiled the least. Does this mean you should carry that particular load? Maybe. Remember I said there are many different qualifiers you should consider when choosing a defense load and this is just one aspect.
Being able to mitigate recoil and keeping rounds on target is important and how quickly you can recover from shot to shot matters.
