Hi Fiveoh. To expand on Paul's answer, the patches are not SUPPOSED to be cut by the rifling, but can, and often do get cut during loading, for the reasons Paul stated. If cutting is occuring, evidence can be observed by examining the spent patches.
The cuts may be in the form of slits in the material, but can also be seen as small-to-large ragged holes, or even the total loss of material on one side of the patch. I've found that most of the time, material failure that occurs off center of the patch can be attributed to some kind of adverse patch cutting.
If you find material failure in the center of the patch, or throughout the entire patch, it's usually due to some other factor, i.e. weak material, burn through, etc.
The tightness you are experiencing during the first few inches of the ball's travel is typical of having too much resistance during loading. The resistance goes away as the ball conforms to the bore, usually after about 6" or so past the muzzle. You'd think the ball would get progressively easier to push down, but in reality, there seems to be that "spot" where it suddenly gets easier. I don't understand it either, but that seems to be how it works :idunno: This condition can be caused by a ball/patch combo that's too tight, fouling in the barrel, or as Paul mentioned, lack of lube. Or a combination of all of the above.
I suggest swabbing between shots to see how that affects the problem. Next, try a different lube. If the problem still exists, then try a different patch material. You don't neccesarily have to go in that order, I'm just relaying what I would do.
Just a side note: If you are trying to find the most accurate load, a consistant amount of fouling in the bore should be kept from shot-to-shot. This means swabbing between every shot, the same way, every time. It's all about consistancy. Bill
