The parenthetical “(0.458″ is half the bullet diameter of a 45/110)” should read “(0.458″ is the bullet diameter of a 45/110)”

Yes, the target is very small and hard to see. When I did my Quigley bucket target, I scaled it down to 10 yards since these days I do most of my airgun shooting indoors. I noticed that it seemed easier to hit the scaled down “buckets” than it should be and wondered why.

That was when I realized that the .177 pellets I was using were WAY too large compared to the scaled down bucket and I began thinking about how that might affect the results.

By scaling the bucket down so much, I had really dramatically increased the relative size of the projectile. It would have been like Quigley shooting at a 17.5″ bucket with a 9.7″ diameter bullet. He could have missed by about 4.8″ on any side of the bucket and still score a hit. In other words, the target size was effectively increased by just under 9.7″–around 55%. My simple scaling made the target effectively half again larger than reality.

So my next step was to scale the targets down, taking the projectile size difference into account, so that the feat of hitting them was comparable to what Quigley pulled off. But I couldn’t see the targets at all then–obviously a non-starter.

So I left them the proper visual size and added the thin white scoring line inside the target. I actually have 3 target sheets, one for .177, one for .20 and a third for .22. Of course they all look the same size but the scoring line position changes.

By the way, I watched the scene again and the horse gallops for about 45 seconds. Figuring about a 30mph gallop–a decent speed for a horse not bred for racing, that would put the bucket at about 660 yards from the target.

Then again, I’ve seen some estimates that place it as close as 250 yards using a stopwatch to measure time of flight of the projectile and the muzzle velocity of a .45/110 blackpowder cartridge.

Any way you cut it, it takes skill to pull the shot off and it’s definitely a fun test of shooting acuity.

]]>That’s interesting. I find one of the biggest challenges is that, at 55 yards, the 1.75 inch bucket is just a spec inside my non-magnified front sight. If I am shooting off hand and holding my breath, as I run out of oxygen, the bucket gets dimmer and dimmer.

Thanks for your insights.

]]>Think about it this way. You can “miss” the target by just a hair less than half the diameter of the bullet and still score a nick (which counts as a hit) on the target.

So if Quigley was shooting at a 17.5″ bucket with a .45/110, he could miss by just under .458″/2 (0.458″ is half the bullet diameter of a 45/110) on each edge and still score a hit. Basically, the effective size of the target was increased by the diameter of his bullet (half the diameter added to each edge).

Generally nobody thinks about such things because .458″ is small compared to 17.5″. The effective size of the target is only increased by a small percentage–less than 3%.

BUT, if you scale down the bucket by a factor of 10, now it’s only 1.75″ in size. Shooting at it with a .22 caliber pellet gun means that you can miss by just under .11″ on any edge and still score a hit. Your effective target size is really 1.75″ + .22″. While .458 was a small percentage of 17.5″, .22″ is a pretty significant percentage of 1.75″–about 12.6%. Which means you’re actually going to be shooting at a target that is effectively 10% larger than what Quigley had to hit.

BUT, you don’t want to scale the whole target down to compensate for the fact that the projectile is now relatively larger than it should be, because that would make it harder to see than it would have been for Quigley.

My solution was to leave the target the same size and make a thin white scoring line an appropriate distance inside the target edges. That leaves the target visibly as big as it should be and allows the shooter to score a hit by seeing if the pellet cuts the white line or hits inside of it.
