I found what i think, is a good deal on a 3-12X50mm Bushnell scope for $75. The store has a few of them and at the other end of the scope, it has settings for 100-200-300-400 yards. How does that work? Sight in for 100, turn the turret to 200, sight in for that yardage and so on? I thought that would be cool to have all of those setting preset and just have to give it a turn to the 200 yard spot if the shot will be that far. If i get the scope, this will be my new sniper rifle
FG,
That's a scope with BDC (bullet drop compensator). I am getting a Bushnell Banner BDC scope for my Apex. If you have the right wheel in the scope, you just sight in at one yardage then youare set for all other ranges. Basically you need to mimic a cartridge. Since you are getting some BS conicals, a 45-70 wheel seems a good choice. I've not looked into it, but I would actually prefer a wheel without yardage but instead just counts clicks, that would give me more flexibility in loads and ranges depending on what I have chosen for a load.
By "wheel" I mean an insert which goes into the top of the scope that has the graduation marks on it for the different yardages. when you twist the top it turns the wheel which in turn clicks off the elevation adjustments. Each wheel is made for a specific cartridge, ie. I have a 100 grain 25-06 wheel in my 25-06 BDC scope and a 150 grain 7 Rem Mag wheel in my 7 mag. To be honest, I have never used the BDC feature. I have the wheels on both riflesset at 250 yards which gives 6" PBR to 280 yards. I shot a few deer from 200 to 250 yards but most have been less than 100 yards. I've never needed to make adjustments for ranges beyond 280 yards while hunting. Now with a muzzleloader, I could see thiskind of scope coming into its own because the projectilesare so much slower and trajectories more curved. Good luck with it if you get one.
