Rifle Scopes S&B Reticle Change

They’re $500 for standard reticles and $900 for Horus.

It would depend what you currently have and what it is you want as to whether you’d be better off to have it swapped, or sell and buy. There are bargains on used S&B’s.
 
Any experience on the timing for a swap? ... want to go from a P4 to a H59.

the cost for a new S&B would well cover buying a slightly used and getting the reticle I want.
