I have been lucky to have found a few Collath drillings and SxS in the last few years.
In two examples, both C1 or 12 Gauge, the chokes were extra full. C1 (Collath #1) has been problematic for me as the typical 12 gauge shell does not fit (atleast in these examples). As I am against rechambering the gun, I am having a good gunsmith build custom "chamber mates" for 20 gauge which I belive will work well. I will report when these are completed.
For the last few years, I have been hunting upland with Collath C3 (16 gauge) drilling which in my examples have been a little snug but work well (I use polywad 16 2.5"). One in particular is chambered in 16x16x 8x57 (.318). It allowed me to take a coyote while in the field for birds....quite accurate I may add.
In my opinion, Collaths are great guns and have proven to be my favorite.
Per the action, I am attaching a few pictures I took when one Collath drilling I received from Cabelas a few years back was missing the firing pin and needed a new spring... luckily, my gunsmith had the capability to handmake replacements.
