Yup, the old school Win. and Remmy crowns that were basically a round over were nothing special for sure. They worked though. The barrels shot fine. The thing people don't really think of is the bullet doesn't see the crown. It sees that the barrel has ended. As long as that ending is square to the bore axis there should be no imparted yaw.I don't like radiuses on crowns like many factory rifles have. I am sure my 375 Weatherby gets some buffering from powder…
Cheers.
There are a few ways to cut buffeting on the bullet. A muzzle device like a brake or suppressor can re-direct some gas away from the bullet's tail. Using a faster burning powder can help a bit by dropping the pressure as the bullet gets to the muzzle, therefore pushing less as it leaves. Some guys (like my Pops) prefer to use flat base bullets when they can, partly so the bullet has less inclination to yaw as it leaves.
