I've heard this rule too, but it makes loading anything for the .300 Winchester Mag impossible. which makes me skeptical of the rule, bc my .300 win mag seem to work pretty well (other than the excessive noise & recoil ...).


Sir,
respectfully

here is a 300 Win Mag factory cartridge, 150 gr. Tipped Barnes bullet. COAL is 3.305" SAAMI Max is 3.340OAL.

Note the pix. there are two markings on the 150 gr. Ballistic tip (green tip). The mark closest to the tip is COAL 3.340" the second closest to the case mouth is 3.305". This would allow for a minimum of .490" of bullet purchase, significantly more than .308"

The second bullet is a 200 grain Nosler Accubond. By my measurement there will be approx. .813" of bullet inside the case at a COAL of 3.340".

Best,

GWB
