Browsing on my Sierra loading app today and it shows 2900 fps with their 225 grain bullet. 79 gr of cfe 223 or 71.6 power pro 2000.
I thought my old load at 2800 was smokin.
Sierra made an excellent point that brass capacity varies widely in the Whelen and I concur. I also believe that chambers vary widely though I only have one. Lots of reamers out there.
But the myth that the Whelen is a range limited round was never true but with modern bullets and powders it is certainly not true.
