need help to replace my action screw

[Willoughby]

I have a Savage 110 FCP in 300wm with a H&S stock
I ordered the Accurate Mag DBM that comes on the FCP in 338 with a H&S stock
but with a 300wm mag- of course to get the 3.850 internal length
the metal fits fine -drop in
but the screws are to short
I have some Rem 700 screws I could maybe cut down & get to work but
I would like to order the correct ones from Savage but their parts finder only works with a serial #
I would like to use correct lenght & hardness screws -
if any one has a FCP in 338 lapua with a H&S stock
and would either let me know the length
or maybe even let me pay you to order some from savage
using your serial # for me ?
any help or thoughts appreciated
