Advise me on a build for my daughter

[FW Conch]

If the round pictured above is the one your rifle shoots, I don't see anything "improved about it? That round appears to be a standard 284 Win with it's SAMMI issued 35dg shoulder angle? As Sniper338 stated above, the 284Win was improved right off the drawing board back in 1963. Should be able to reload it with standard dies.

But, if a smaller 6.5 is desired, there's nothing wrong with that. But I would defiantly hold on to that barrel :-)

Good Luck, and let us know how it goes :-)... Jim
