There is definitely compound but only around the screw hole and behind recoil lug. It is not a full bedding like I am use to see.

Thanks

That's probably the dollop of white-yellow-greenish stuff that Weatherby puts in there. I find it usually is cracked if the rifle has been used, and is of little good.

Bedding at least the recoil lug, if not the action, will definitely help. This is especially true on a 30-378.

Re: Accuracy problems wby 30-378

How many rounds has the barrel had through it. If the round count is low I would inspect to see if the RECEIVER was threaded square with the bolt face. I have had 3 30-378 that were good enough to met quality control inspections but definitely not good enough for sub moa. If this is the case Weatherby will true and thread correctly. All other replys are good but will not fix any machining issues. On a side note The 30-378 is the most problematic out of all hunting caliber Weatherbys. This is due to powder that is being used to get the highest velocitys. Many people shoot tight groups at 100 yds and finalize there. I would strongly suggest looking at some Norma powders followed buy the Hodgen extruded lineup. Switch to Win MAG primers. And load to 3.8 to 3.85 coal depending on the manufacturing tolerances of your box. Let us know how it turns out...

my suggestion would be to try a diffent bullet. In my experience either a gun loves barnes bullets or hates them. You can throw alot of money out there buying barnes bullets try to find that majic load that may never come.
