Colorado law states the max round cound count for a rifle is 5 rounds. This means your magazine can NOT hold more than 4 rounds. It has to be 4 rounds in the mag and one in the chamber. If you are using the PSL you have to modify the mag / block it so no more than 4 rounds will fit!! There are some expanding rounds for hunting with th 7.62x54 I have a few. They are close to 30-06 round and I have taken a deer or two with them. I hope this helps
