I'm keen to keep using the open sights on my 458WM. I have got a set of Warne QD mounts and they are fitted onto a Tasco scope - this is fine for my Trailboss loads (ie reduced) but I know normal loads wil break this scope, so I take it off. I'll get a good scope one day.

With the open sights, the lighter the projectile the higher it hits above the target, eg:

500gn projectile hits 90mm above the bead at 100yards
400gn projectile hits 240mm above the bead at 100yards (can still aim low on the target to get central hits)
300gn projectile hits 660mm above the bead at 100yards! (I have to pick a spot in the dirt below the target to get a hit on the target)

Anyone know of someone that makes a taller front sight for these rifles? (the site is fixed to the base in a loose "north-south" dovetail with a spring loaded button to stop it sliding off)
