If I understand you right your getting a single stage press?
If so whether you start reloading pistol or rifle, get a reloading block either a multi caliber or the 50 round individual caliber blocks. Then whether you get a powder measure or weigh individual charges on a scale, you can place your loaded cases in the blocks. When the block is full you can look in the tops of all the cases in good light to check your powdr charges to make sure they all look and are charged the same.
Then you can start to seat your bullets. It's a good way to avoid a light or no charge or a double charge.
If your actually getting a progressive press, ignore this.
