Spot,... the way I do it, (YMMV)!!
I put 'bout 1 1/2" of the "tick'n strip" in my mouth, then I center the "lubed" tick'n across the muzzle of my rifle, place a ball on it, then "start" the ball 'til it's flush with the muzzle.
Next, I gather the "excess tick'n" with my left thumb'n index finger, pull the material "up", and slice it off (flush with the muzzle) with my knife.
Be careful to cut "away" from you, and it's also good to "not" have the ramrod stick'n up high'er then the muzzle, 'cause the brass ramrod-end will dull the blade edge if struck when use'n this method. ::
