Found the Magic Pill
« on: August 26, 2017, 08:49:06 AM »
For my Weatherby Vanguard S2 in 257 Wby Mag.
117gr Sierra Game King
69gr IMR 7828
Primer CCI 250
(Best group)O.A.L. 3.25
*Be warned this is prob at or near max so approach with caution*

Playing with seating depth I started at 3.19" and worked my way up .01" at a time. Groups only got tighter. First pic is 3.20"
Best group is 3.25"

Thank you to all on Weatherby Nation that gave me advice on my load development.

Cabelas didn't have any Accubonds in stock so I shot all Sierra today. Still gotta try to duplicate this group and see if I can get Accubonds (which is what I really want to hunt with) to do the same.

If you can't tell... I'm beyond thrilled with this rifle at this point!

I don't own a chronograph but I'm estimating this load from the data I've read to be around 3300 fps. Am I wrong?

With that kind of accuracy, I wouldn't be concerned with velocity.  Very Nice!   :)

That'll work
Sorry... Yesterday was the last and final day for any and all complaints whatsoever.

I try to avoid temptation unless I can't resist it.
