I plugged the numbers of my pet 35 Whelen load into quickload, and adjusted the parameters of my case capacity and seating depth, and QL shows me at over 70,000 PSI!
Here's the load:
310 gr Woodleigh Weldcore
56.4 gr RL-15
CCI large rifle primer
2350 fps actual
24" Ruger Hawkeye 1/12 twist
Woodleigh says 57.0 is max with RL-15. Last year, I used the ladder method to work up from 52.0 gr to 57.0 grains of R15. I got the best accuracy with 56.4. I have ABSOLUTELY NO high pressure signs from the load... no flattened primers, sticky bolt, anything... seems like I have a winner (also got a moose with it- full pass through, DRT at 80 yards).
But obviously, QL says I'm lucky to be alive. Anyone got ideas/ experience with this?
