Inconsistent Pressure Signs

I shot 4 shots today and 2 of the four showed alot more pressure that the other 2. This is a .270, I'm shooting 150 gn. Nosler Balistic Tip, this time with 49.5 gn. of IMR 4350. Nosler shows a range of 48 gn to 52 gn with this powder (actually nosler tested H4350), 52 gn. is like 2782 fps. It has showed pressure signs no matter the load or the O.A.L. But today kinda confused me with the inconsistent pressure signs, two of the primers were flattened and the other weren't. Another thing, you would think using less powder would cause the bullet to hit a little lower but it hit about 4 in. higher. Any suggestions?
