hi matey I shoot a 17 rem, ive shot it for 25 years, so I think I know how to clean a 17, here,s a tip if you are using a 17 size bore guide, get a 22 cf one I clean my 17 rem sako vixen with a 22 cf bore guide, and a good 17 rod and jag wait for it? and 22 cf patches, 1 /1/8 size it sounds weird but it works, the 17 patches are all to small they are made for air rifle.s, an American shooter showed me how to clean a 17 rem years ago the problem you are having is the 17 bore guide it to small I hope this is of some use to you dave.ps if you want ill show you you don't live far away.
