No you will need a balance beam scale(accuracy and price-go with lee unless you want to spend more) -if you plan to weigh cases, bullets and completed cartridges go with a better scale!, Trimmer with a chamfer deburring tool-make sure it has all your collets.
Dial calipers to measure length, ogive headspace or whatever you decide to get pressed about in the future. DO WORRY ABOUT LENGTH THOUGH.
