I will have to be forgiven for asking.... how one gets 3261 fps from a 160 gr bullet in a 264 WM,when the exact same case will not give that velocity safely when necked up to 7mm? confused

What charges and how long a barrel does it take to do that?
73gr of H570 that's my 3 shot average. I managed to score 3 lbs. of the old powder That they quit making. It does show signs of pressure but still ejects with ease. I am using a 30" barrel but when I use the book charge that was for the Hornady RN I match there 26" barrel very close.


Well.....signs of pressure and a 30" barrel...I guess I would not call that running rings around a 7mm Rem Mag.Hardly a valid comparison.



The 280 Remington is overbore.

The 7 Rem Mag is over bore.
