Posted specs are 3.340 in. as stated by Shoney . Thing is with the 300 Win. Mag. they very often run out of magazine length before you get the bullet anywhere close to the rifling lands which seems to be the case with butta9999 and in my Browning A-Bolt as well . I actually had to go with the Barnes 168gr TSX with a COAL of 3.360 and that being all my magazine would allow and the bullet being seated .055 off of the lands. Barnes bullets for whatever reason tend to favor longer bullet jump than other bullets and was the answer for my very elusive sweetheart load . I could get many others to fly as well but were seated too long for the magazine limiting me to one in the chamber and one only in the top of the mag as that one would have the bullet tip resting over the feed ramp. If this turns out to be the case with yours as well my load for the bullet I listed is 73.0gr of IMR4350 , Federal GM215M primer in a Federal premium case for a speed of 3225 fps and 1/2 in groups @ 100 yds, sub moa at 200 yds.
