Those images look off to me.

The bead is way too big in relation to the V.

Never ever seen a fine sighting like that. Hiding three-quarters of the bead under the V. The bottom of the V sighting should show the full head circle nestled in the bottom of the V fully visible.

The other sighting method is to level the top of the bead level with the top of the V. As I understand it, this is the usual method. Though I learned to shoot using the bottom of the V method. I find that more accurate.

The writer of the article talks about his much leisure and that determines which sighting method you use. NO! It depends on how your rifle was sighted in.

Personally I also do not understand these old books referencing shooting the bottom of a circle target. I know this is very common. Instead of aiming say the top of the bead, or the centre of the bead, directing where you want the bullet impact. Subject to trajectory of course.

Aiming the bottom of a circle approach. What size is the circle? Is it 6 inches? 12 inches? Is your rifle sighted to shoot three inches or six inches high? And at what range? 100 yards? 50 yards? 200 yards? With a multi leaf express sights, are all the leaves sighted to always be aimed six inches below the target aim?

Plus I have never seen a 12 inch convenient circle on an animal! I'll pick my aiming point, calculate six inches down and Sim there. Or this charging buffalo, that's the brain, I'd better aimmsix inches lower however .... I've seen the bottom of the circle advice. Never use it! Maybe why I often shoot too high? But the rifle range is different from the field.

Recently I attended a BGRC visitor day shoot for another club. All firearms were provided. All had some sort of V sight. Some rifles were obviously designed for the bottom of the V. Others for the level top of the V. In some cases the V was so big, the bead would be lost floating at the top of the V. Only nestled in the bottom of the V would provide good accuracy.

Was a good day, shooting lots of different strange rifles. Iquite enjoyed the .303s. Lee Speed versions my guess. I want one!

I much much prefer the wide Express V to those aweful narrow notches usually on modern open sights. Often these completely hide the target.
