In the new cabelas catelog ,they are selling a bullet drop compensating scope for the new leveroution (spelling ?) ammo . The have three models 30-30 45-70 and 444 . All scpoes are compensated for each calliber. My question is , Which calliber would best replicate a .50 cal muzzleloader. At $99 these scopes seem ideal for a bullet drop scope for a muzzleloader also
