Wowsa, a 280 out of a 358 STA with 86 of H4831 @ 2856 fps or something like that...

For quite some time I used the 250's and H4831 in my 340 for about the same kind of speed and if I recall right I was running 85 grains.

I have no knowledge and or clue (which is totally obvious) but that seems like an awfully stout load for a 280? Doesn't it...?

Thx
Dober
