I don't know if you have the Stoney Point bore guide, but the insert has a slot or port .
Unless it fits into the chamber, the solvent will leak into the magazine.
The guide is a two piece brass colored anodized set that works by twisting the two offset pieces and it wedges itself to keep from moving.
I wish I could post a picture.
Thanks for your reply !

In case anybody is curious how they look, Midway still shows a picture of these bore guides .
I called Stoney Point. They must have sold out awhile back, because they are in Kansas, and these bore guides list a New Ulm Minnesota address.
Of course they could not help me, that's understandable.
Thanks for the interest guys !
