Think it would stabilize the 170 Berger or 175 Sierra? Now that would make it a loonnnngggggg range rig!!!! What's the custom ammunition loaded with, bullet wise
Custom loaded ammo is with:
New Weatherby 270 Weatherby brass
N560 powder
Nosler 140 Accubond bullet
Federal 215m primer
As for shooting other bullet. I have no idea how the will shoot. Rounds fire had been the custom ammo and some Weatherby ammo for backup.
