Which grain?
I'll take a look! Load development pages are really helpful for me to get an idea of the process for a particular bullet. ThanksHere is my experience with the 275s and the 338 Lapua:
My 338 Lapua Magnum by Cloud Peak Gunworks
Pressure Test Complete (by .5 increments): 90 - 92 grs of H1000 / .020 off (3.009) 91.5 - Had ejector marks and slight bolt lift. 92. - Had ejector marks and heavy bolt lift. All shots fired 2 minutes apart.www.longrangehunting.com
