Are there any solid reviews on this site or others on the current Hornady Superformance Ammo? Specifically .270 loadings. I noticed on their ammo they claim 3200FPS with a 130 gmx from a 24" barrel - that is flat out humming. That bullet at that speed would be a flat hammer.

My current Nosler Partition loads are maxed out with a 130 at around 3150 behind w760.

I am mainly curious if the advertised speeds are actual and what is the "typical" accuracy expectations as well as velocity spreads?

Thanks
