Remember somone saying that Sand B ammo was .310 in Diameter and that privi partizan was Boat tailed therefore not so good for older bores.
Is S&B boat or flat tailed (the 180gr FMJ stuff) and what is the diameter of the PP ammo?
Then next question.... which is going to have a bigger effect on accuracy, having a larger Diameter to engage the rifling OR having a flat tail. Just about to start reloading but I have to buy some commercial ammo first.
