I am interested in shooting paper patch, but could not find through the search engine, a description of what constitutes a paper patch chamber versus a grease groove chamber, if there is any great difference. Any help would be appreciated.

Re: Paper Patch Chamber
J.Murphy,
There are a million opinions of what makes a paper patch chamber different than a grease groove, but basically, the effects are tiny at best. If there is one somewhat unifying notion, it is that paper patch chambers for target bullets are very tight - often too tight for grease groove bullets to chamber. But paper patches in a standard chamber intended for groove+ diameter grease groove bullets, will shoot paper patches very well.
Bottom line is that whatever chamber you have, is good enough for paper patching. Go for it!

Re: Paper Patch Chamber
You can shoot bore diameter and groove diameter PP bullets they both shoot well but you will loose powder capacity shooting a groove diameter and this can get to be an issue with small capacity cases when you get to longer ranges.
I like tight chambers and longer funnel types of leads. It's a personal choice.

Re: Paper Patch Chamber
BUT, you do not need to lose case capacity with a GG bullet IF it is a two diameter design
as the base band/ bands can be fire formed case/"groove" diameter and the front bands can be bore diameter and
so they can be seated way out.
That being said, do not forget about the DDEPP/ two diameter PP bullets that work very well in std GG chambers.
Same deal short Base band "patch to fireformed case I.D./freebore/groove dia
and body at "patch to bore/lands" diameter. typically seat way out with only maybe 0.1-0.125" into the case
similarly to the dedicated tight neck chamber to use straight sided patch to bore bullets.
Nice about the std chamber: can shoot BOTH the 2 diameter GG and the 2 diameter PP bullets Well.

Re: Paper Patch Chamber
Oh, there are a number of 40 and 45 caliber DDEPP/two diameter PP bullet molds
listed, described and illustrated in the Buffalo Arms Catalog.
