[QUOTE="Brown Dog, post: 37156, member: 1622"] Prepping for an upcoming Scottish trip has forced me to blow the cobwebs off my 300 -and I've finally got hold of some 180 Accubonds and noticed my magazine will allow me to seat them about 5mm longer than SAAMI standard. Not sure how this change will affect internal ballistics. Would one of you out there with “Quickload” be kind enough to crunch the following data for me in order to find the recommended optimum charge weight for the following: Calibre: 300 Win Mag Barrel length (breech face to muzzle): 25.787in (65.5cm) Powder: Viht N165 Bullet: 180gr Accubond Brass: Norma OAL: 3.515in (8.928cm) [longest OAL my magazine will permit –still short of rifling by 1.45mm!] Primer: Fed 210M (ie not magnum primer) Very many thanks!
