POPCan Someone run Quickload for me?
I need 2 loads evaluated. Both are for the 378 WBY Mag using FED 215 BR caps.
One is 115gr of IMR 7828 with a 270 gr Barnes XLC at 3.685" C.O.A.L. The other is 114gr H4831 SC with the Win 270 gr Failsafe. The barnes X are clocking 3200 fps the Failsafes 3100 fps. What are the approximate pressures? Thanx in advance!

<David>These Quickload results assume a 26" barrel. Quickload has no way to evaluate the effect of different primers (there is no way to select the primer).
For the Barnes XLC with 115gr of 7828
64235 PSI and 3145 fps / slightly over pressure, Quickload lists max pressure as 63816 psi
For the Fail Safe with 114gr of H4831SC
60426 PSI and 3056 fps. This is for the Combined Technology Fail Safe, they did not list Winchester Fail Safes.
