The 320gr Woodleigh round nose Weldcore doesn't have near the shank left under the cannelure as the Protected Point version of the same weight, i think you'll have plenty of room for your charge of Varget under that bullet, plus, we all have basher loads, i like em, in fact several cartridges of mine happily live right there.
These can all be loaded up or down, especially in the cases of 458 WM at 3.575 COL, a 500gr trophy bonded Sledgehammer solid at 2358 fps is the load in another rifle, the Gibbs will run those 600gr Woodleighs to 2500 fps if one cares to sit/stand behind it, i have, it's only fun for a little bit! ; ]
