Issue with semi auto and "hot" ammunition

[jrw]

Any of you guys have issues with semi autos not extracting some of the newer high muzzle velocity rounds? Have two different Remington 30-06. Fine with normal ammo but as soon as I shoot hornady, etc they are not ejecting. Thanks!

Is that the Hornady light magnum?
Isn't there a recomendation on the box against using it in a semi auto?
It's been so long since i've messed with that stuff I can't remember.
There is some ammo on the market that won't cycle properly even on a bolt action, the Prvi Ppartisan in 243 has a habit of locking up bolt guns.
If your gun won't cycle a certain ammo, simply don't use it- it's not that there is anything wrong with your rifle, it's jus that the pressure curve of the ammo is wrong for it.
