[QUOTE="Calvin45, post: 2894197, member: 109862"] Wow that’s a huge difference. In my very limited experience with chronographing factory ammo ive found Winchester to generally be pretty true to advertising, just with the cheap super x ammo. In fact in a former weatherby vanguard with a 24 inch barrel their 150 grain power point load actually BEAT their box velocity by about 40 fps, it was legit over 3250. That was nice. In my 22 inch 270 the the 150 power point was right on the 2850 that they advertise. Federal soft points were always about 50 fps slower which I though was forgivable, they had the tightest es numbers of the stuff I chronoed and were the most accurate on target in my .270. But their fusion line…very accurate but a .270 shooting a 150 at 2700 just makes me sad haha. Remington was a whole other disappointment. I chronoed a 243 100 grain corlokt load at 2600 fps on the dot. A full 360 fps slower than advertised. And it was a 22 inch barrel on a savage 99 that was well worn but that’s not enough to explain this. Winchester still hit 2900 or so with the same weight. You could even hear and feel the difference shooting this box of corlokts, weak. The .243 isn’t a powerhouse to begin with… [/QUOTE]
