If it will not fit, the bore is probably too tight for easy loading. The no go gauge should not fit in the bore at all. If it can be inserted into the bore of the muzzleloader, the bore is probably too loose for optimal accuracy. However, you may find that the sabot will still give satisfactory performance.
