Finally fired and used the Chrony on the Nosler 130 grain Accubond they shot 1/2 groups and velocity 3,075fps. The box listed its velocity at 3,100fps so pretty close. The only thing is I paid $65 a box so that sucked.

WHOA 1/2" thats GREAT.............65Bucks a box, guess I'll have to load some!!!!! Have you tried the Winchester 140 factory stuff? They shot 3/4" outta mine, didn't chrono them though......
Yea $65 a box is pretty expensive. I pick up some accubond. 130 grain to start reloading them cause they shot pretty dam good. I was looking in the nosler reloading book and they don't list data for US869 or Retumbo powder. So my question is where do you get data to use these powders
Hodgdon's data shows 70.5 grains of Retumbo pushing a 120 out at 3299 fps with 61,700 PSI. If you're getting over 3600 fps with one, I think that's a bit past the safety margin. Unless you've got a 34 inch barrel.

High vel, but I think Hodgdon uses a 24" barrel for this data. That would not make a hoot with a 308, but a 264 with Retumbo it could easily be 100FPS. I have seen recent articles fron W. van Zwoll & others that load a little heavier & of course these should be approached with caution. I don't see a problem with 3450-3500fps, but my Number 1 might tell me otherwise, we shall see. But yea, 3600 is movin on!!
Nice my rifle has a tight chamber too. I like Retumbo but so far US869 seems to be the powder that works for me. I'm using winchester brass CCI primers and COAL 3.350
Some one over @24 hour did a test on which primers where the hottest as per the post there is a difference, and is why if I have a decent load/group I'll try a different primer just to see can I get a little tighter!
