Needs a little modification - Hoppe's 9 Viper Cleaning System

I am a big fan of Boresnakes for all my shotguns and only purchase the more expensive locally produced ones. Though I typically do not use them for precision rifles, I do for things I plink with. I recently purchased three. One for the 44 Magnum, which worked perfectly and one each for the .17 and .22. I used the .22 one in my Henry Golden Boy as you can not use a rod from the chamber. The brass end tip is slightly too large and it was a real problem getting it to do down the barrel so that I could pull it out and I was also afraid that it might not be really good for the bore. With some crimping pliers, I make the diameter smaller and put a coating on it and now it works fine.
