    Prone- Slung and Biopod

    To Natural Point of Aim Now that you've built your position, the butt of the rifle is solid into your shoulder. That butt is compressing the clothing, fat, muscle, etcetera, all the way down to where you've got a consistent foundation in your shoulder. The sling is supporting the rifle, and...

    Prone- Slung and Biopod

    I would challenge each shooter to investigate the placement of the forward elbow, relative to the centerline of the rifle. "Wag" the rifle left and right, as you place your elbow in different locations relative to the centerline of the bore. You will feel the resultant tendencies, and you will...

    Prone- Slung and Biopod

    The next point is absolutely critical, and controls BALANCE. You've heard all kinds of folks talking about the recoil of the rifle, and how the darn thing bounces around all over the place. Well, there are a bunch of reasons for this "bounce". One of the predominant reasons has to do with...

    Prone- Slung and Biopod

    Now, remember where your forward hand was positioned on the forend of the rifle, when the butt of the rifle was firmly lodged into your shoulder. It's just a little tricky here, but the key is to place your forward hand on the stock at the same place as where you were able to achieve good butt...

    Prone- Slung and Biopod

    The next series of pictures show the progression of donning the sling, of "wrapping the sling", and of attaining roughly a good prone position. Thousands of words could be used to describe the progression of steps, but I hope these pictures do a better job than words. Again, please forgive the...

    Prone- Slung and Biopod

    This next picture shows what happens when you slide your hand out too far AND have too low of a forearm position. Note the position of the head and the eyes: Very un-natural, and strained. Not good. So, too low of a forearm position does tend to cause this awkward head position, as does too...

    Prone- Slung and Biopod

    You'll also notice too that we've not added the sling yet. It's important to understand the fundamentals of the rifle and the shooter, before adding the sling. The below picture shows the rifle slid back into the shoulder, while the forward forearm maintains roughly the same angle. This is...

    Prone- Slung and Biopod

    This first picture is used NOT as a practical analysis, but rather to show that you start with the above position (roughly), then you simply add the rifle to it. In this below picture, you'll notice that the rifle is placed far too forward in the FORWARD hand, and as such, the butt does not...

    Prone- Slung and Biopod

    forgive the ugliness Well folks, if I can start posting some pictures, there's two things you notice: First, I'm not a Hollywood actor, and I don't look like one either. Second, it might be better to let the pictures do the talking instead of 1,000 words. Let's see where this goes... Oh...

    Optimum barrel length for .22LR

    Hey RG, Yes, the propellant is actually almost all burned out in the first inch, depending upon any cylinder gap or throat. Now, the "push" continues after max pressure, so just because all the powder's burned out, it does not mean that the GAS is not still working on the base of the...

    Not satisfied with my Remington 700's group size...

    Well, it seems that we have two schools of thought. First is that pencil-thin barrels just can't shoot, and the other that the OP just can't shoot. Ultimately, none of us know the answer, but it has been fun reading all the ideas. The one thing that no one has mentioned yet is "Scope...

    Gunsmithing I Know I'm Gonna Get Hammered ;-)

    You say it's bedded to the rear tang. Is it possible that the glass...hmmm...how do I say this? OK, you certainly have a vertical wall of glass, just behind the recoil lug. Do you have ANOTHER vertical wall of glass, just behind the rear tang? If so, grind this vertical wall of glass behind...

    Primer rupture help

    OK, I'm going to retract part of my statement, but re-confirm another part: If a primer manufacturer "pinch-trims" the lip of the primer cup, and leaves a jagged edge (like a burr), or if that locally worked area becomes "work hardened" compared to the rest of the primer cup, then a leak, with...

    Primer rupture help

    If you have a look at the edges of the primers that have been fired, you'll note that they're no longer radiused. They're now square. I would ask the OP to prime a shell, load no powder and no bullet. Fire that primed shell in said rifle, and take a picture of that fired brass. Let's see the...

    Primer rupture help

    Somethings wrong, and I suspect it's your chamber/bullet seating depth. According to a reputable website, IMR 4350 should generate ~ 62,500 psi at 69.5 grains. You're at 65 grains. According to my red-neck math, you should be at about 55kpsi with that load of 65. However, you're definitely...

    Night Vision Another sounder wiped out.

    This video certainly shows that it can be fun to eradicate the little buggers. But, if you're a farmer, you know the economic costs of hogs on your land. If you're serious about Hog elimination, I'd suggest you investigate Jaegerpro. My friends run it, and their methods are spreading across...

    Advanced Marksmanship "Reading" wind

    Well, as is the case when dealing with various interpretations of a situation, a great many thoughts can arise. Sinister has got it right; he's well versed in LR shooting. I am almost sure that there's a lurker out there who could blow the doors off of everyone now chiming in. The New Yorker...

    .338LM + 300 Bergers = fail

    You'd probably better get a comparator from Sinclair. Don't measure to the tip. Measure as you would with a "ring gauge", somewhere off the ogive. I take it you're also attempting to "jamb" the bullets into the rifling? If not, how far off the lands are you seating? I think some folks will...

    Large change in accuracy with barrel temp

    Lowlight is likely very right. Many quality barrels are heat-treated to relieve internal stressors (stress relieved). Cheaper barrels are generally not heat treated. You'll normally notice a degradation in accuracy when an economy barrel is heat-stressed. Better barrels WILL show some forms...

    Advanced Marksmanship "Reading" wind

    I won't claim to provide all the answers, but I will throw in my 2 cents. First, know that wind closer to the shooter has the greatest effect upon the path of the bullet. As the bullet gets closer to the target, wind does not have the opportunity to "redirect" as it does when it's close to the...
