This is the LPS load and as mentioned above has a steel core. It is boat tailed and is 32mm in length and weighs 148 grains. The M1908 is flatbased and has a lead core. The M1908 is 28.6 mm in length and weighs 149 grains. The M1930 looks like the LPS (in that it is a boat tailed bullet 33.2 mm in length) but it has a lead core and weighs 182 grains - and it has a yellow tip.
The silver (or white) tip colour is now generally omitted as the LPS is now the sole ball loading in Russian service and the need to use a tip colour to differentiate it from other loads has now passed.
