use approximates very closely to the behavior of the 
service rifle in that respect. The muzzle velocity has 
been taken at 2060 f. s., and the value of “C” at .415. 
Working by Handco'ck’s table, and after slightly adjust¬ 
ing two of the results, the following angles of elevation 
were obtained: 
50yds. 100yds. 150yds. 200yds. 250yds. 300yds. 
2.0' 4.3' 6.6' 8.9' 11.4' 14.3' 
Metford’s table gives an angle of 4.4' for 100yds., and 
15.8' for 300yds. Hardcastle’s table, published in these 
columns on Dec. 16 last year, gives 9.0' as the 200yd. 
angle. From these angles the following values of drop 
are obtained, drop being the distance which a rifle must 
be aimed high to hit a mark at a given distance: 
50yds. 100yds. 150yds. 200yds. 250yds. 300yds. 
1.05in. 4.50in. 10.37in. 18.64in. 29.32in. 44.92in. 
From these values an ordinary table of trajectory has 
been compiled. The official Text Book says that when 
using 200yds. sighting the bullet is .4 of a foot high at 
the halfway distance. This is equal to 4.8in. Our table 
gives the same figure exactly, but this is merely a co¬ 
incidence, as the true calculated value might vary be¬ 
tween the limits of .35ft. and ,45ft., viz., 4.2in. and 5.4in. 
All that can be said is that the two tables are in ap¬ 
proximate agreement on this point. Shooting with 
300yds. sight adjustment, the Text Book table says that 
the height at 100yds. = 1.0ft. = 12.0in., and at 200yds. 
1.1ft. = 13.2in. Our table gives these values at 10.5in. 
and 11.3in. respectively, implying a slightly flatter trajec¬ 
tory, no doubt due to the higher velocity and better 
shape of bullet assumed, 'the differences are in any 
case very near to the limits which practical shooting 
tests could distinguish. These values, the only ones 
available for comparison, show that the table to be 
introduced, while more acurate in detail, makes no 
bold bid to strike out a new line of its own. It is merely 
a fuller table, and in the matter of odd inches in greater 
accordance than any other published figures with the 
latest statistics of the service cartridge. 
Quotations only have been given so far from our own 
table of trajectory. This is because the table which we 
propose to publish lias been extended to show the 
amount of drop which the bullet sustains after passing 
the distance for which the sights are adjusted. Fre¬ 
mantle once published such a table for the .303 rifle; 
but his table was. we believe, based upon the assumption 
that the line of sight was level with the barrel at the mo¬ 
ment of the bullet’s departure. Giving the foresight a height 
of ihree-quarters of an inch above the axis of the bore, 
an assumed value which is near enough for practical pur¬ 
poses, material corrections must be made in a table which 
aims at extreme accuracy. For instance, when using 
100yds. elevation to hit a mark at 300yds., the table value 
says aim 31.4in. high, but the height of foresight necessi¬ 
tates a reduction of this allowance by 1.5in. This may 
not be a practical difference, but the existence of a source 
of error of this extent stultifies the use of highly exact 
figures throughout the table. It is possible that the ex¬ 
istence of this source of error- accounts for the absence 
of particulars in the Text Book tables for drop values 
beyond the sighting distances. The particulars are of 
very great practical importance to all shooters who are 
called upon in the exigencies of the amount to take a 
shot at an object, the distance of which is clearly dif¬ 
ferent from that for which the sights are set. We ac¬ 
cordingly place before the reader a trajectory table for 
the .303 rifle, with an assumed height of foresight of .75in.

All values are given in inches. 
A 50yds. sight adjustment is clearly unsuitable for the 
.303 rifle, since it multiplies errors at the longer dis¬ 
tances, without giving any compensating advantages 
near to. The same remark applies in a lesser degree to 
* u hlOyds. setting of the sights. . With 150yds., on the 
f) 1 t ' 1 “ r ,hand, the errors at the nearer distances will but 
slightly exceed 2in., while at 200yds., viz., at 50vds. be¬ 
yond the sighting range, the drop is only 4.6'in. At 
250 and 300yds., allowances of approximately 1ft. and 2ft. 
respectively must be made. The ^OOyds. adjustment 
makes a 4.4in. allowance necessary at the middle dis- 
tance and reduces the necessary lift for a 300yds. shot 
t? p . W-G’n.. and so forth for the other adjustments specified. 
YY ith this table before him the shooter can easily ap¬ 
preciate the niceties of snap shooting at short ranges, 
and he can gain a great deal of useful knowledge con¬ 
cerning the behavior of his rifle.—Field (London).

Most of the members are now turning their attention 
to the evening indoor shooting in preparation for the 
coming matches for ihe fall and winter events. Regular 
shoots are held Tuesday and Saturday evenings, with 
special practice between times, including ladies’ use of 
the galleries on Thursday evenings. Saturday after-
