I see a bit of a pattern there.
As I mentioned in my post above I found the 100gn Ballistic Tip quite hard in my .250. Velocity is 2772 fps (20 inch brl) and the bullets are from about 20 years ago. I bought a heap back then as they were very cheap and still have some left. My load is 39gn H4350 and that was the max charge but I see the data now lists 40.5gn H4350. Maybe a bit more velocity would help the 100gn Ballistic Tips to open up more? But the 100gn Hornadys shoot into an inch or less so no real need to go back to the Noslers. The 100gn Ball. Tips are good killers in the faster .257 Roberts with an extra 350 fps.
