I've tried making my own and so have a lot of others at RFC, for less than $14 you can get one specifically for the .17 and 500 patches that are made for the tiny bore, quite a bargain if you ask me...and it won't break like the home made one leaving the patch and melted stub stuck in the bore!! If you do break one, they'll replace it free of charge, no questions asked..........well, they might ask if you double patched it which is about the only complaint I've seen on em!!! :oops:
