I don't have a 7mm-08 but i do have an 18" .243 and it's both loud and breaths fire lol. Running 105gr Berger VLDs at 2700fps (max load). Has a bit of a muzzle flash
Most people go .308 for 16-18" rigs because the higher the overbore ratio on the case, the more hit you're going to take for chopping the barrel short.
"Combined synergy of a man and rifle is matchless, the steadiness of hand and acuity of vision, and finally the art of knowing how to make the rifle an extension of the body, all equate to the ultimate synthesis of man and machine."
