This is all the old catalog said about this one:
311413 The Squibb gas check bullet for the Springfield and other .30-06 rifles. Perhaps the most accurate gas check bullet yet produced. Excellent for target practice up to 600 yards. Has also been largely used for small game shooting in the Northwest, particularly for ducks at long range. Makes a most excellent load where one wishes to save the wear on his barrel from the full charged factory cartridge. Powder charge 16 grains Du Pont No. 80 powder, or 23 grains Hercules Lightning powder. Also very good for other 30 calibers. (GC, SP, 169 - TP is 413)

Ah, this one is more interesting:
257231. This is like the No. 308206 Kephart. The front groove is for catching dirt or holding lubrication. These different weights will be found good for all of the various .25 calibers. (PB, FN, 66, 88, 111 Also Perfection – TP is 420)


ldeal Series of .25-Caliber Bullets No. 257,23. The Iron Age, 23 Jan 1902, pg 62.

The Ideal Mfg. Company, New Haven, Conn., are offering molds for a new series of .25-caliber bullets, shown herewith. The shape of the extreme point of the bullets is referred to as being such as to permit their being seated in the shells with the regular tools for the 25-20 single shot and repeating rifles; also for the 25-21 and 25-25 Stevens. The bullet of 66 grains weight, it is said, will be found a very good one for short range, and the 88 grains weight is alluded to as being correct for full charge for the above mentioned rifles. For the 25-35 Winchester and 25-36 Marlin high pressure quick twist rifles the three different weights, it is remarked, will be found very satisfactory; the 111 grains weight for 200 yards, 88 grains weight for 150 yards and the 66 grains weight for 100 yards or less. The bullets are formed on the lines of the .30-callber Kephart. The base bands are wide and strong, so that they will not jump the quick twist. The forward portion is made small enough, it is pointed out, to obviate the possibility of the lead striking the barrel, while the front groove is for holding lubrication. The edge of the forward band is left sharp to act as a dirt scraper and catcher. It is stated that the lubrication will be the first to touch the barrel, and thus obviate leading. It is shown that with these bullets a greater number of shots may be made without cleaning than otherwise. Single molds will be made for any of the weights specified; single weights to cut off the point, and molds for casting all three weights.

You are very welcome JS47 I had a feeling we have been talking about two very different designs. Thanks to Fitz's input I had a better idea of what to look for in regards to finding a good picture of what I believe he described.
