The following letter is of interest to military riflemen, not only on account of the detailed description of the ammunition used, but also from the fact that the elevations required at the various ranges are given:
“Headquarters Twenty-second Regiment Engineers,' .N. G. N. Y.Broadway and Sixty-eighth Street, New York City.Ideal Mfg. Co.,Jan. 6, 1906.
New Haven, Conn.
Gentlemen: .
The reloading outfit ordered for our armory came duly to hand, together with the 35,000 metal gas check cups for bullet No. 308290. .As you requested in formation relative to results after we got started, I am pleased to report as follows:
The shells we used were the Frankford make. They were prepared as per your instructions; the primers were U. M. C. new No. 9 non-mercuric; powder charge was 21 grains of Laflin & Rand Lightning powder. To get this your Universal Powder measure No. 5 was set half way between 28 and 30 grains. The bullets No. 308290 were cast in armory mold, they were lubricated, and the gas cheek cups pressed on in the lubricator. Samples of these bullets I sent you for your inspection and criticism, three of them as cast, the others after being lubricated and the gas check cups affixed.
The implements thus far seem to be working satisfactorily, and the ammunition made looks well. To test the shooting qualities of it‘, three or us went to Creedmoor Jan. 3, which was a very unpleasant day, -snow, rain, hail and a three o‘clock wind blowing hard one minute and stopping the next.
We started at 200 yards and on my second shot I started a string and made 49 out of 50 off shoulder with no windage on sight, and the elevation was 325 yards. At 300 yards I shot 425 yards elevation and one point wind. Walter Lamb ex-sergeant, Twelfth Regiment, now superintendent or Creedmoor range, tried it, sitting position, and after firing a few shots to find it, made twelve consecutive bullseyes. We then went back to 500 yards and with sights set at 690 elevation and 1 ½ point wind, I made two 24's and one 25. By the time we got back to 600 yards, it was so dark I could scarcely make out the bull, but Sergt. Lamb made one 22 and two 23’s. For this distance we had sights set at 775 elevation and nearly two points wind. Lamb stated he did not think the full service load could have done better.
If the 35,000 rounds that we are making for this spring's outdoor work prove as satisfactory as our first trial, we will be well satisfied. Ex-Sergt. Dardingkiller of the Twelfth Regiment is now reloading our ammunition.
Respectfully yours,
W. B. PORTER.
