[QUOTE="Calvin45, post: 2466381, member: 109862"] Well…I’ve consulted my idiotic brain (the crystal ball previously mentioned) and predict 2867.8 fps (yes, .8 included) Now I’d like to tell you that it’s based on something intelligent. I know that’s a good bit less energetic than the hammer load you worked up. And I could account for my prediction with the btip having all kinds more bearing surface and no pdr voodoo grooves and such…but here goes: it’s all the metric system’s fault! .270 cartridges are designated as 6.8mm in metric. So obviously 680 meters per second makes sense. BUT only works out to 2244 fps. Somethings missing. Gotta pay homage to the fact that it’s not a metric cartridge. So obviously you add 277 to this total. And 170, that’s the bullet weight, it just makes sense. Add 64.5 to reflect the case length in millimeters and 47.3 to indicate how many hundredths of an inch the case head diameter is (continuing to acknowledge both imperial and metric measurements to be diplomatic). Finally, today is the 65th day of 2022 and only an idiot wouldn’t account do this in his calculations, so add 65 too. Adds up to 2867.8 [/QUOTE]
