[QUOTE="Catfur, post: 812015, member: 41271"] Just running with your bullet (using a basic online, browser based ballistic calculator). Nosler recommends 1800fps for expansion of the ballistic tip (from their catalog). Using a G1 BC discounted 5% for Nosler's "Optimistic" published BC. At ISA, you have 575 yards until the bullet drops below recommended expansion velocity, 400 yards before you hit the 1000ft-lbs that many go by. 400 yards is farther than the overwhelming majority of deer will be shot at, and 575 is starting to get out there pretty good. Using, as another example, the load I am working on in my 6mm, and a book estimated max load velocity, with a 6mm 105gr VLD, I will have 1000ft-lbs out to 600 yards, and minimum expansion velocity out to 775 in ISA. In atmospheric conditions I'm likely to encounter during my deer season this fall, I have 1000ft-lbs out to 700 yards, and 1825fps at 900 yards. I'm nowhere near a good enough shot (yet) to be comfortable taking a shot at a deer at 700 yards, let alone 900, so I figure I have more than enough rifle to get the job done for any shot I am likely to take (my 300 RUM would kill a deer at artillery ranges). Find a ballistic calculator you like and play with the numbers. [/QUOTE]
