tkharris, i rented a new M1 20gage at the lodge. It worked well and they cleaned the gun each day. The fee was $50 US per day which i thought was reasonable. So i did not take a gun, but several other hunters that went thru customs with me in Cordoba did not have a problem. Even though the birds were flying high on most days their were hundreds of them. We used RD ( Brazil ) shotgun shells which were a little dirty and i had a few duds,but overall they were ok. My best day was 825 birds @ 60 %. I had a great time. Larry
