true for the 9,3x53R Finnish but the 9,3x53R Swiss isn't more than a hot 9,3x72R load. this two cartridge's may look similar but playing in two different league's. the Swiss round is a roe deer and
chamois cartridge from a time when wild boar and reed deer were almost non existent in Switzerland.
notice that the 9,3x53R Swiss is the rimmed version of a 7,5x55 open up to 9,3mm. the measurement's are very close to a 7,62mm Mosin basic case but this is pure coincidence.
