So I have recently picked up a 30-378 Weatherby mag from my dad, we are 2nd or third owners of this rifle. I'm having a hard time getting a decent group out of any ammo or load I try. Rifle is Weatherby Mark V, 26" fluted SS barrel with magnaport type break. Synthetic stock. Black hawk rail with cabalas guide series 4-32x 30mm tube 50mm objective scope. I've removed the bi-pod and sling, and I am shooting off bags. Cleaned the be-jubs out the thing. I found action screws loose and reset them. Removed rail and checked for square, furthest back bolt needed to be filed down to run the bolt and to tighten rail firmly. Tried 2 different optics, one of the cabalas and one Leopold 3-9x 40mm. Both zeroed at 50-100yrds but 200M is a crap shoot. I give my barrel 5 min to cool between shots.
The platform seems to be in working order but shoots random and sub-par. Any input would be welcome.
