Bolt action Nosler 125 Partition load

[BjornF16]

Working on a 125 Partition recipe for my Savage Grendel.

So far, have loaded a couple of dummy rounds with Hornady once fired brass after resizing using a Redding 6mm PPC Type S neck sizing die (.287 bushing). Bumped shoulder back approx .001-.002". COAL ends up at 2.303" with a .010" jump. Cycles just fine in the Savage with room to spare for the magazine.

Looking at using 8208 XBR for its' temperature stability. Developing load in Texas but plan on hunting in Colorado mountains.

Planning on the following loads for ladder testing:

27.4
27.8
28.2
28.5
28.7

Any suggestions appreciated.
