Thread: Redundant Calibres

@Bill999 do you mean the westerner of the new SIG 277 fury. Both not the same but I know exactly what you mean about projectiles. the only thing is the newer ones usually need a higher twist rate and that is something 270s could've had for years, Same deal for one of my projects, 264 win mag. You will always hear me banging on about their twist rates. Its standard 1-9 from memory but a lot of the new projectiles need better than that as they are longer. They hype up the 6.5 man-bun as being able to beat it out past 400 as they can use the slipperier projectile even though they lose 2-300 fps. If the 264 had that it would mash it to bits.
400 is a long way for me I might add so I'm not worried. I'll take the extra horsepower up close.
