If you are not cutting your patches at the muzzle, here is something to try. Using the recommended diameter patch is fine if you get them centered on the bore perfectly. A little off center and you get gas leakage that blows apart the patch.
On my rifles I use the next size up for patch, for example in my 50 cal. I use patches for a 60 to 69 Cal. and in my .36 cal I use a 40 to 49 cal patch. The advantage is, if the patch is slightly off centered on the bore like happens, it still seals very well.
Try it you'll like it.
