Has anyone had any issues with the 452 American in 17HRM? The local gun shop had a customer bring a gun in that was rupturing the cases and sending gas back at his face. The gun was sent back to CZ with some ruptured cases and this was their response.
"Checked headspace, was slightly tight. With Rem ammo neck expansion measured 0.002" and 0.004" on body at body/shoulder junction. 1 in 5 cases split. They were included. The reason 17HRM brass splits is because when it is necked down it gets work hardened and it makes it brittle. The ammo manufactures do not anneal it because the brass is not reloadable so it is not worth the effort for them. Test fired good."
Does anyone else think that reply from CZ is crazy? The same dealer has sold hundreds and hundreds or Marlin and Savage guns in 17HRM and they don't have case ruptures.
What have others seen in their 452 American guns.
