another data set to burst some bubbles. In these six 15" encore barrels, the cartridges that have bore diameters closer to the cartridge case width (350 magnum and .308 win) performed differently regarding powder burn rate and velocity than the cartridges that have wide case diameters in comparison to the bullet diameter (6.5-284 and 6mmbr). Using the fastest powder in the top 7-10 best velocity loads from Lee, VN, and Hornady, I get near long-barrel velocities in the 350 rem mag and .308 winchester (with no pressure signs), but with the 6.5-284 and 6mmbr (skinny bullet and fat case), the velocity spread between the fastest powders and best velocities powders is much closer.
Stated differently, fat bullets and skinny cartridges perform differently than skinny bullets and fat cases regarding powder burn rates, velocities, and barrel lengths--at least in these 15" rifle cartridges. If someone can explain why the factory produced TC encore barrels contradict the accepted truths of burn rate, barrel length, and velocity, please tell me.
And don't even bother telling me that I don't know how to reload--I reload for 23 different cartridges, using A&D medical lab powder scale, best cases, best bullets, meticuluous case preparation and loading, best dies, and best reloading presses.
