Turn the jag down?
Jeepers, just experiment till you find a patch size, a smaller jag size, or a different slotted tip that works.
It's really not rocket science.
I buy 2x2 patches, use as is or cut to fit whatever caliber needs cutting with whatever jag or slot I'm using.
Covers .45-70 on down to .22s, and scissors are do-able by even coordination-challenged fumblefingers like me.
