The invention described herein may be manufactured and used by or for the Government for governmental purposes without the psyment to me f any royalty thereon.

Another object of this invention is to provide a testing target which minimizes the personal factor involved in testing small arms.

Another object of this invention is to provide a, target for small arms ahd the 1ike suitable for instruction 053 persons in target shooting.

Still further objects .nd a'dvantages of the invention Will be in part apparent and in pa1t pointed out in the-following description of a preferred. embodiment as shown in the accompzmying draWihg, in which:

Fig. 1 is a view of a conventional .ta1get.

Fig. 2 is a view of a targetaccording to the invention.

Fig. 3 is a, view of the sighting alignment of a 'small firearm using the conventional target of Fig. 1.

Fig. 4 is a view of the sighting alignment of a. small firearm using a target according to the invention.

Figs. 5, 6 aand '7, are views of modified targets Within the purview of the invention In sighting a, rifie having a front blade sight and a rear peep sight, the top of the blade is centered in the aperture 0f the rear sight and, holding this alignment, the top of the biade sight is positioned so that the botoom of the bulls-=eye of the target appears to be tangent to the top 01 the blade and the center of the bulls-eye is in alignment With the vertical axis of the front blade. This is the correct alignm8nt of the sights am! target irrespective of the range, and is illustrated in Fig. 3 of the drawing, wherein I repamentiled April 30, 1928; 370 O. G. 757) resents the rear peep sight, 2 repres ents the front blade sight and 3 represents the bulls-eye of the conventional targetshownin Fig. 1.

Referring for a, moment to Fig. l, mhe target equal tathe apparent width of the frontblade sight. It has been found that at this particula-r range sighting is gre-atly simplified becauseof the ease With which the vertical sides of the front sight -are aligned With ehe edges of the bu1ls-eye. For all otherranges, the apparent size of the bulls-eye will not;allow 015 such easy sighting.

Rifles produced in laxge volume must be proofed, and a proo fing proc;edure haue, been adoptecl involving the use of a st'andard barget having a fixedsize of bulls-eye and used ab a fixedl range.- Under these conditions the bu1lseye 3 is too small completely to fillout the width While vertical aiming of thegun is relatiVely simple, lateral aiming, is much of the front sight.

more difficult because it in'xiolves the alignment of the estimated center of the bulls-eyewith the esti1'natedvertieaI axis of thefront sight. The personal equation, therefore, plays a major role in causinglateral dispersion ofs-h0t groups 0 2 different riflemen. 4

I have overcome the aboVe mentioned sighting difficulties by superimposing upon the conventional target a, sighting bulls-eye l (Fig. 2), 01 a. size diifering from the conventional scoring bulls-eye B, corresponding 3 of Fig. 1. 'Ihe sighting bulls-eye differs in size from the scoring bullfs-eye, the size of the former being selected for the particular range and apparent relative dimensions of the front anal rear sights 01 ehe rifie, and the size 01 the latter being selected in relation to the ballistic characteristics of the rifle. The sighting bulls-eye is designed in the figures shown to just fi1l the space between the vertically extended sicles of the front sight. Of course, the sig hting bullseye may be smaller or larger than the scoring bull, again depending upon the range.

For every target there is selected ari arbitrary tical diameters of the two bulls-e'yes also coincide insofar as their respective lengthg permit. This is clear1y shown in Fig. 2 wherein the sighting bulls-eye 1 and the sc0ring bulls-e'ye 8 are tangent at their lowest points. Such an arrangerangement makes it immaterial which of the two bulls-eyes is used for sighting and the airhing cf the gun is thus not afiected. However, the large bulls-eye makes it easier properly 1:0 align the rifle with the target.

An inspection of. Fig. 4 will show the correct alignment of the rifle with the targ zt using the improved sighting bulls-eye.

Alternative modifications of my improved target are shown in Figs. 5, 6 anal '7 wherein the target is shown aligned with the sights of a rifie. In Fig. 5, 9 is the scoring bulls-eye and I0 is the sighting bulls-eye which latter is semi-cifcular' in shape. In Fig. 6, H is the scoring bulls-eye and 12 is a. sqt1are sighting bullseye. A similar device is shown in Fig. 7 in which I3 is the scoring bulls-eye and 14 is a triangulr sighting bu1l -eye.

The material of construction of the target forms no part of the present invention. I1: may be made in any convenient manner, as will readily be apparent to one skilled in the art. 1A printed target is to be preferred, bui; a, target, may can- Veniently be made by superimposing a cut-out bulls-eye in proper relation upon a conventional tai'get.

It will be apparent that many modifications within the scope of the invention may be coustructed by one skilled in the art in the -light of the discl'osur: of this specification.

'I'he modifications shown and described herein are 1:0 be taken as mere1y illustrative of the invention, and not limitative thereof, the following claims defining the scope 0f the invention.

1'.- A target; comprising a circular scoring bu1lseye and a, circulzir sighting indicium eccentric 130 and la'rger in siZe than said bulls-eye, the peripheryof said bulls-eye being internally tangent t o the periprery of Said sighting indicium at, the lowermost point thereof.

2. A target for a, gun equipped with a rear sight having a peep-hole and a front sight having an upstanding blade, said target comprising a first bulls-eye and a series of rings concentric thereof and demarking zones of radially outwardly diminishing score values, there beirig asecond bu1l y eye superimposed over and larger thari said first bulls-eye, said first and second bulls-eyes having one point only of the lowermost portions of their peripheries in common, and said. second bullseye having a transverse dimension equal that subtended by said blade when viewed through said peep-hole from a predgetermined range.

3. A target for a gun equipped With a front sight having an upstanding blade and a, rear sight having a. peep-hole through which said blade and ehe target Viewed in sighting, saia target comon1y of the lowermost portions cf their outer boundaries in common.

4. In a target, a, first circular bulls-eye ha.ving a plurality of rings concentric of said first bullseye defining areas of progressively decreasing score Values radially outwardly, a second circular bulls-eye superposed on and of larger diameter than, said first bulls-eye, bulls-eyes being tangent at their lowermostperipheralportions) and said second bulls-eye and one 0f said rings being tangent ab their uppermost peripheral portions.

5. A target according claim 3, setzond bulls-eye being in the form of the upper ha1f of a circle of larger dia'meter than said first bu1lseye, the horizontal diameter of which is tangent to said first bulls-eyeat. the lower portions of its circumference.

6. A ta)rget according to claim 3, said second bulls-eye being in the form of a. square, the lo'wer horizontal edge of sai;1 square being tangent to said first bulls-e3re at the lower portion of its circumference.
