280 Rem & 160 Swift A-Frame load - anyone?
- Thread starter Ltbull01
- Start date
Using a 160 Speer Mag Tip with 58.5 of IMR7828. My records show 2900 fps but since it is rounded to 00's, it was probably based on one shot over someone else's chrono. I know I had some lower velocities when I was working up loads and ended up 2 grains over my book's max.
I can't speak to the A-Frame, but Scirrocco's are tricky to load, I got wicked pressure spikes with them as I worked up the load.
Very long bearing surface, the Aframe is like a bulky Partition, make sure you work up. If you haven't bought them yet, they are very expensive and there are lots of choices that will work just as well, TSX etc.

hope its not too late.
Reloading manual Swift number one. first printing may 2002.
barrel 24" Wiseman Case Remington Primer 9 1/2 remington barell Twist 1-10".
the powders available are H1000 H4350 H4831 RL19 RL22 RL25 IMR4350 IMR4831 IMR7828
it indicated that H4831 is giving lowest standard deviation on velocity.
see you and tell me if you need the datas.
