Hi, I picked up a Ruger 10/22 last week, my first .22. One of the cleaning videos I watched on Youtube mentioned a jig that Brownells sells to drill a hole in the back of the receiver to allow you to use a cleaning rod from the breech side. I just used my .22 bore snake. I would like to be able to finish up with clean patches, is feeding the rod from the other end REALLY that bad for the rifle? I'm not going to pay $50.00 for a drilling jig that Im only going to use once. I always go from the breech side with my pistols and shotgun because direction of bullet travel is was I was taught. Any info? Thanks in advance.
