Hammerdown,
Yes. I personally prefer the Call gold bead, as the round bead, for me, tends to reflect light toward the side the sun is on and my shots drift accordingly. With the square topped Smith Call gold bead front sights, I personally sight in for the bullet to impact at the top of the front blade at 25 yds., using the bead mostly to catch my eye better than a plain patridge.
However, with FA flat bead front sights, the top of the blade is not square, but round. These I sight in as you apparently do, by centering the bead in the center of the square notch rear then zeroing to place the bullet in the center of the bead @ 25 yds. This seems like an odd concept for an old target shooter to adapt to, but it has worked well for me for years out to iron sight distances where the bead begins to cover too much of the target. The "V" express rear blade is too imprecise to satisfy me.
Interestingly to me, although I've shown this technique to several other shooters and although I know it is not unique, you are the only other shooter to ever mention it to me. We must both be awful old...or else " great minds think alike."
S.B.
50 yds. is not what I would call "longer distance". Handgun Silhouette shooters began to see the potentially disruptive transition down from supersonic back to subsonic closer to 100 yds., depending upon the ammo and barrel length. At 50 yds. a great shooter, rifle, and ammo should stack 'em in a hole, whether the ammo is super or subsonic.
