I went down that road. It's a long, dark, road. Too many at the club were shooting with MVs in the same range and doing well using similar rifles. I stopped looking for excuses and started doing a better job at reading conditions.The reason I asked is because I have had problems in the past with accuracy going south when the bullets went trans sonic.
In my case, long before 500 yards.
Some bullets seem to fall apart beyond 300. The general finding is longer bullets of the same basic shape do better. It could be transonics. Upping MV made groups get huge. Maybe getting them up to 2000 fps or higher might fix both. But it makes for more recoil and target damage in my case.
I started down this path with a .38-55. Even tried breech seating. Moved to .32-40 and put the .38 in the rack. I have the bigger bullets. Should probably revisit this winter.
