The triangle of tension
 Login/Join

In his excellent book, Rifles for Africa, Gregor Woods discusses the "triangle of tension" or lockup for good shooting. Essentially, the bottom three fingers of the trigger hand pull slightly into the shoulder pocket while the shoulder exerts an equal amount of thrust the other way. The cheekbone is "welded" to the top of the comb and exerts equal pressue downward.

I tried and it works well for creating a solid hold. However, when putting my cheekbone on the comb I cannot see the front sight of the irons. Does this mean I need a taller sight element?? Or how is this overcome??

If your sights are zero'd then it sounds like you need a taller comb.

Are you far off? Will the thickness of a leather buttcuff ammo carrier or one of the adhesive recoil softening cheekpieces bring you into line? I have a similar issue with my Guide Gun "Mjolnir." It handles like a birdgun but my sightline is just a wee bit low when it comes to the shoulder. I'd have go custom to get the sights any lower so I'm looking for ways to raise my face on the stock just a 1/4 inch or so.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.



What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

actually, i'm not sure if it's the sights or the stock that is the issue. seems to me that if i lose sight of the fri=ont sight element when i weld the bottom of my cheekbone to the comb but can still see the rear sight then perhaps i need a higher front sight element? yes, no?

and Mike I'm looking to lose 10 lbs not put it on!

Before you change the sights or stock, I would suggest you "weld" your cheekbone down on the top of the comb of the stock and fire several rounds with your face in that position.

Of course, you won't be able to see the sights, and you'll need to fire the rifle safely with that in mind.

After you fire 10-rounds or so, I'll bet your cheekbone hurts and is starting to swell. That will vary with the size of the caliber, but in my experience, you need a bit of a gap between your cheek bone and the comb with a big-bore rifle.

On a shotgun, this type of mount is required. On a big-bore, it's like taking left-hooks from Mike Tyson.

Heym USA is right on the money. Then...there's the bone sructure of the face...you know, high vs low cheek bones, width of face..etc.

Triangle of Tension...isn't that what our wives/girlfriends possess?

Weld your cheekbone to that?...hmmmm, that could work. I can't attest to where the swelling would occur though.

That's why I dislike straight stocks.

It can start in a couple different places, but it usually ends up around the eyes.
