Oskar,
Every rifle is different and every handloader is different. I have a couple 9.3x72Rs and an 8x72R, so I'm hesitant to shorten long cases if I can use shorter, available cases. Once I get the lathe set up, with appropriate stops, it is no problem to thin and turn rims. I haven't been able to find a good 6.5x58R at a price I can afford. I didn't want one, until I read of your experiences with yours.
Mike
