[QUOTE="D.ID, post: 726255, member: 14340"] Those are extreme variances but it happens. I always suspect the chronograph even three different ones that where calibrated while the stars were aligned and my horoscope said it was my lucky day. However in my 338 edge (unique at 24") I went up to 94.5 grains with the 300s and with each .5 grains I gained about 25fps consistently untill 92 then a huge jump up of 75fps then 50fps then it dropped way back down and the last couple charges rivaled about 88 grain loads in fps and hammered primer pockets. FPS can get extremely inconsistent in an overloaded case. Including going down as the charge goes up. I currently run 89.0 grains of h1000 behind a 300smk in rem brass, on a cci250 out of a 24" for a true 2781 fps. Chronographs lie but gravity and brass life will tell you the truth. [/QUOTE]
