[QUOTE="ar10ar15man, post: 1578047, member: 106836"] big problem with JAM is it also jumps pressure...quickload says add about 7200 for starting press. you did not say for hunting or target? i agree no reason to JAM hunting loads. i start all my work up AT THE LANDS, TOUCHING no jam. clean the gun....zero copper in the throat it takes work, polish a bullet, seat, look and marks and change seater, do it all over again. till the marks go away, then make it longer .001 at a time till you see the lands touch( it helps to have a nice clean square throat) you are at high pressure point for your max load, anything else will be less pressure. if you go to jam, you KNOW you have to decrease and work up.
