The Pro1000 overall cartridge maximum clearance height is 2 5/16" or 2.3125". Anything with an overall length of this or longer cannot be loaded on the press. This is because the Shell Plate will start to index before the cartridge is completely out of the Bullet Seating Die, and would cause indexing and adjustment issues.
2.3125” is 58.7mm.
Popular cartridges that cannot be loaded on the Pro1000:
303 British Overall length 78.11 mm (3.075 in)
308 Win Overall length 71.1 mm (2.800 in)
6.5 Creedmoor Overall length 71.8 mm (2.825 in)
Etc.
The Pro1000 offers excellent value for money when it comes to loading handgun and semi auto rifle (223) it is not suited to loading bolt action rifle loads.
If you are looking for a press that can load decent amounts of handgun and most of your bolt action rifle loads have a look at the Lee Precision Classic Turret Press.
