300 wsm 180 gr Barnes

[Deputy Sheriff]

I was looking at Barnes reloading site and they list 68.8 gr of HV100 produces 3144 fps. This is quite a bit faster than any published data for 300 win mag 180 gr. Is this a misprint or has anyone come close to those numbers?

QL says that load should run over 86000 psi with a 180 TTSX. Speed is close with QL predicting 3155 fps in a 24" barrel.

Wow pressure looks too high, I believe 64,000 is top end.

Do not try that load.
