Hi everyone,
I just loaded up some Woodleigh 405 flat-nose into cut-off 300wm brass to keep the 458x2 fed. My goal is to find subsonic loads from N320 and Red Dot. I haven't shot any yet, but I have ladders worked up in N320 from 17 to 20gr and with Red Dot from 15 to 18gr.
But a question came to mind about my max pressure. Is it safe to assume my max pressure is the same as it was from the original 300wm parent case (SAAMI 64,000 psi)? I have been playing around with GRT and while I don't yet know how accurately it predicts for this rifle, it is fun to play with. GRT predicts 60kpsi and >1870 fps with Woodleigh 405 using 56gr of 4227 and it comes with 41 ft-lbs recoil.
Merry Christmas to all, and to all a good night.
