I also use the 180 grain Speer Spitzer flat-base Hotcores which have the exact same point of impact at 100 yds. Sounds like that might be a better option. The only thing is, the lead tips get flattened in the magazine with the recoil. My third load is the 150 grain E-tips at just over 2900 fps...I'm thinking they might be a bit too hard.
