I am helping my uncle get his new build up and running. It's a 300 weatherby built from the ground up by a good local smith with premium components. Topped with a new nightforce SHV F1 and nightforce rings.
He did maybe 10-12 rounds for break in and then wanted to get a load dialed in.
Shooting 180gr hammer hunters in virgin weatherby brass over RL 23, fed 215M primers.
At 77.5 and 78gr he shot three shot groups with all holes touching. Going around 3150 with 20fps ES. Very promising and typical in my experience with hammers. After some more "tinkering", he starts to get large 2-3 in groups...so he comes back to the 78gr load and it sprays a 3in vertical dispersed group.
We checked screws and mounts nothing appears loose.
here's the "kicker" (pun intended)...most of this shooting is being done from a Lead Sled. I hate those things and won't use them but he likes his. My theory is that he's losing scope zero with that much recoil into a solid wall!
Any other ideas??
