You need a reloading press....nothing fancy just a simple single stage press. A great press here. Nice because it lends it's self to being mounted upside down for sizing (An advanced option...lol)https://www.ebay.com/itm/RCBS-Jr-2-RELOADING-PRESS/264153408073?hash=item3d80c52249:g:kc4AAOSw6IdcOMJy:rk:7:pf:0Then this from NOEhttp://noebulletmolds.com/NV/product_info.php?cPath=564_104_410&products_id=2415Then select your bushing sizes you want to use for sizing your bulletshttp://noebulletmolds.com/NV/index.php?cPath=564_104_412Will need the push through punch for the caliber you are sizinghttp://noebulletmolds.com/NV/product_info.php?cPath=564_104_412&products_id=3011Some info on youtube.
Peter, I went with this little low cost Lee O frame press. The arm can be change to any location you wint. Not many presses allow this. I mounted it upside down and it is a dream to size AG bullets with. I went with the NOE system, which makes different sizes very low cost and quick to change.As usual, noe workmanship is first rate. Love this system!I use imperial sizing wax for lube. with this system I can size from .260 to .251 in one step. which is not supposed to be possible. I am getting very-very good results. For longer bullets, I size to .256 and then step down to the .251 or .250 for a given bullet. For the .257, I size to .2575. One step only. Makes life a little easier.
