Warning:
Remington does not recommend this primer for use in the 17 Remington, 222 Remington, 223 Remington, 204 Ruger, 17 Remington Fireball. Use the 7-1/2 Small Rifle Bench Rest primer in these cartridges.
This 6-1/2 Small Rifle primer is primarily designed for use in the 22 Hornet.
Heard the same thing about Winchester Primers. Never had any problems with them either.
