What is the relationship between barrel length , caliber, and case capacity? I would assume a longer barrel with a larger bore diameter would allow more powder to be used. I would also assume that a short, small bore would require less case capacity to be as efficient. If that's true, what cartridges align to different categories better?
26" barrel .33 caliber = 33 Nosler or Lapua
26" barrel .30 caliber = 300 win mag
26" barrel 7mm caliber = 280rem
26" barrel 6.5mm caliber = 6.5 creedmoor
26" barrel 6mm caliber = 6x47 lapua
