The 311277 casts a nice little 90 gr RN bullet. I've used it in 30 Luger, 30 Mauser/Tokarev, 32 S&W & S&WL, 32 H&R and in the 30 Carbine in handguns. In rifles it makes an excellent plinking & smal game bullet in just about any .30 cal cartridge. I load it over 2.7 - 3.2 gr Bullseye.

Not think I have the same thing this is a plain base bullet about 180-200 gr. by the looks of the mold.

From the first Lyman Cast Bullet Handbook:

311277

Another early German design bullet (refer to 311256), nose diameter .300, 1st band .317 dia, base .308 dia.

Apparently at one time there was a school of thought that smokeless powders required a sealing band just ahead of the case mouth. It's sort of like a German "stop-ring" design except those had the ring so the reloader wouldn't have to resize the case necks to keep the boolit from falling inside.

Thanks, might be of limited use for me....

My 1935 handbook lists it as "197 grs, .30 Gov't. '06"

There is a number of heavy 30 caliber bullets that were designed in that number sequence, most by Dr. Hudson. These were trial and error type designs at a time when they were trying to find a good 30 caliber bullet suitable for practice in the 30-40 and early '06 years. Back then they didn't give the guys crates of ammo for practice. Hudson finally invented the gas check with 311284, which was sorta the crowning achievement of all the work put into finding a way to make your own full power .30 loads without what he called "fusion of the base" With the help of UMC producing the gas checks and John Barlow of Ideal making the molds, 311284 was the result. I would venture to guess that your mold, 311277, wasn't one that produced the best results and therefore has little mention, even in my catalogs of 1903 and 1910.
