[QUOTE="redleg1013, post: 1924558, member: 49994"] To the point of the thread: to teach about overbore. This, while drawing an arbitrary line, did the best when I was first reading PO Ackley's work. [URL unfurl="true"]https://www.accurateshooter.com/technical-articles/overbore-cartridges-defined-by-formula/[/URL] Essentially, you're going to take the H2O case volume and divide by the bullet diameter in inches. The other thing that I've learned about the "barrel burners" is that a lot of competitors use them, and the strings of fire is what does the majority of the damage. If you were to subject your rifle barrel, continuously, to the heat and pressure it endures while firing, it would last for just over one second, which thermodynamicly makes sense, as heating is not a linear increase, but logarithmic. Sorry, starting to wade out into the weeds. I would think, given those parameters, a 7-08 might be worth looking at. [/QUOTE]
