I have an omega bdc scope. Just switched my scope from my omega to my encore. Shot it last night and dialed in at 100 yards. Here is my question. I know that they are set for 150 grain loads but I am shooting 100 grains of pellets. I am shooting a 200 grain shockwave. Have anyone used this combination? What are the experience with the yardage coresponding with the circles. I am dead on with the crosshairs at 100 but I have to jump to third circle to be dead on at 200. What does the circles corespond with what range from your testing?

I have no experience with these scopes. The "circles" are supposed to be 150, 200, 225, 250. You say you need to use the third circle to be on at 200, so you are shooting at a little less velocity than the scope is designed for.
You could increase your charge a little, or adjust the scope so the bullet strikes slightly higher at 100.

Those circles suck. Need a center dot or something. I prefer to not buy these gimicks instead opt for traditional duplex reticles and use the heavy part of the post for distance.

I love my circles..to each his own.Just cause you don't like em doesn't mean they suck..I love mine. I think Traditional duplex reticles suck..Different strokes for different folks..I also think Thompson Center sucks, but you don't see me posting that do ya?....oops I just did. |

I will second what Timex says. Just get a good Leupold standard recticle scope, sight the gun in dead on at 100 yards, then shoot targets at 50 yards, 150 & 200 and measure exactly how much high or low your bullet groups are at each yardage. Then record that info and put a little sticker on your gun with the data.
When you hunt use a laser range finder, then hold accordingly.
Another important point regarding sighting in a muzzle loader, Clean the gun between every shot so you get truly consistent conditions. Your killing shot in the field will be out of a clean barrell, so that is how you need to zero in.

870 as you can see in the chart you are kinda in between solid range points with a 200 grain load. You may consider moving up to the 250 recommened load and see where that puts you. I know some do not like BDC but I can tell you from experience if you learn to use them and trust them they can be extremely useful.

Leupold.....and im sure others....will install a custom reticle based on ballistic data you provide.
Just a thought.

My Savage shoots better with a Fouled barrel, After I clean I shot a few Caps through it also, I have never used a BDC Scope, I use a Leupold with standard recticle, and I sight mine in at 1" high at 100 yards, But with a Savage the Loads are way different than your's, where I can change loads very easy, I shoot 67g of Reloader7 but can also shoot as low as 62g of powder and change My POA very little. But I have a Friend that shoots with a BDC Scope and he loves his, and I think he zeroed his in at 100g of pryodex cubes? and he has never had a Problem hit his POA. Best of Luck getting this figured out.

I entered your info into spot on this is for a Omega bdc 250.... 100 grains of powder 200 gr shockwave... MV 1430 fps i56.tinypic.com/kaoad4.jpgThat's pretty cool software. I, too, have a T/C Omega with a Nikon Omega 250 BDC scope. I'm using Triple 7 powder and a 250-grain Shockwave sabot. I understand that the BDC is set for three pellets (150 grains) but the brochure that came with my pellets said to not exceed two pellets. They're probably just saying that to cover their own butts, but I went ahead and set it up on two pellets. I sighted it in at a coworker's range since my bench at home was rendered unusable. A quick check with my laser rangefinder revealed that his 100-yard target was actually 113 yards. So, my main crosshairs are zeroed at 113 yards. I shot it at 200 yards one day this past week, and the bullet impacted the center of the third circle down (15" low). I figure that halfway between the first and second circles should be pretty close to 150 yards. If you ever get a spare moment and could figure my BDC for both 100 and 113 yard zeroes for my load, I'd greatly appreciate it -- no photos necessary, just data. If not, no big deal. Thanks!  |

I also hate the circles. I have Burriss scopes on my rifles with Ballistic Plex reticles and love them. My muzzleloader however has the same scope you are talking about. The reason I got it is because I was shooting for Nikon at the time. My contract has since ran out and I am now switching to Burriss after the season. I never could get those Nikon BDC reticle to be accurate like they say. IMO theres too much going on in the Nikon scope with the circles. Too much room for error.

How many people like the op bought one and dont have the resources to ask the questions he did? I bought my son one for his 20 g slug gun. He can shoot it but I dont use the circles, Im 30 years into this and have a hard time w this new ...stuff. |
