[QUOTE="LoneTraveler, post: 1791984, member: 77249"] Every Weatherby made rifle I have dealt with has excessive free bore. . Roy Weatherby designed that into the rifles back many years ago so he could get velocity with the available powder of the time. H 4831 was the slowest market powder available to reloader in that era. Case neck thickness, Case length, and distance from diameter on bullet ogive to rifling in the barrel all have affect on pressure. Most reloading books state, Their printed loads are to be used only in Weatherby rifles because of the free bore in their rifles. The reloading data is based the OACL they post with the bullet being used. Go by the loading books and be safe, [/QUOTE]
