Curious if someone could chime in on any mods or build-ups on the TRG-S Sako in the .338 Lapua Mag. I have the TRG-S - M995 Lapua magnum Caliber rifle. I'm thinking of upgrading the barrel and doing some bedding and other such upgrades but pretty much still using the original stock and so fourth. Has anybody done this before? Please provide me the good and the bad.
