Bushnell DOA with a 250 reticle. It is made for muzzleloaders. About $150.00. I use a rangefinder along with this and can hit a clay pigeon at 250 yards holding dead on with the doa reticle. The muzzleloader is whipping a T/C shockwave 250 grain out at over 2000 fps. That's crazy for a muzzleloader. Nikon binos are mid range but well worth saving for. Even if a guy puts 20 to 50 dollars a month away it will add up and before ya know it ya got what ya want. But again if ya can afford it I like leupold because they are tested tried and proven along with a no hassle repair policy.

I have heard alot of god things on the Nikon Omega with BDC for muzzleloaders. Don't shoot one so i can't say from experiance.

Optics,
It's not to hard to fall into buying a bad set of optics for far to many reasons for here. However, Since the purchase of my brand new scope I have a major amount of hind site.
What are you hunting?
How much gun do you need? (243, 30-06, 7mm, 22, 410 ect.)
Now matter what gun you choose, setting the right ammo up and knowing how to read the riase\\decline at specific yardage. (50, 75, 67, 400,?
Then practice. more then just the two weeks before your hunt.
