Good handloads can't fix lousy bedding.
My Mk4#2 was driving me nuts as no load jacked or cast shot decently. (50 yards)

Just because encasing rifles in wood is a bad idea, I took off the upper handguards and both bands.

Just ordered two books on accurizing the SMLE. Only "bone stock" military rifles I have ever owned that would shoot 1 moa or better were pre WWII 03s, Persian Mausers and M 38/96 Swedes.
