Back to Basics: Primers ,

https://www.americanrifleman.org/art...asics-primers/

Using pistol primers in a rifle might mean pierced primers, as the hammer spring/firing pin spring is too strong. Also, pistol primers don't have as much fire as rifle primers, so in a rifle cartridge they might not ignite the powder the same, giving strange burns.
Just hope your rifle action is well enough designed to vent 50-55k PSI of a blown primer away from your face.
