[QUOTE="dchamp, post: 678716, member: 51652"] Can't argue with those kind of groups. I ran your load (270wsm- 72.6mm oal- 70.0gr's of N570) with an estimated 66cm barrel length with quick load and here is it's estimated prediction; 925 m/s (3037fps)- pmax 3171 bar (45995psi) - 92% propellant burnt -100% fill. With a 250M zero at sea level it shows a 7cm rise at 100M and a 1M drop at 500M. Please let me know if these numbers are close to what your getting as generally quick load has been realitively accurate but occassionally off with it's estimated predictions. dchamp :) "Political correctness is tyranny with manners." - Charlton Heston (1924-2008)] [/QUOTE]
