Hi all,
I have a rem 7600 in 35 Whelen and was trying loads for it - I used a federal large rifle primer with remington brass and a 250 gr hornady round nose bullet. I started with 50 gr of RL15 and was going to work up to 54 gr.. i must say i am normally very conservative with reloads looking for decent hunting accuracy and never pushing the pressure/speed envelope.
The fired brass came out very hot to the touch with the 50 gr load and the primer was a touch proud - no other signs of excess pressure. same thing with the 51 and 52 gr loads so i just stopped there. I tried 4064 in the past and got the same results - very hot brass with slightly proud primers.

any idea what's up with this? I am going to get a box of factory ammo and see what happens with that.
none of my other rifle reloads have brass this hot.

wondering if it could be something with the gun?

thanks for your thoughts.
