The big conservation outfits (DU, PF, RGS, etc) regularly supply their chapters with guns for their banquets. So the answer is yes . . . but individual chapters also acquire guns to auction or raffle from local sources. Works best if someone in the chapter has an FFL, can handle the paperwork, make the phone call etc at the banquet so auction/raffle winners can take their guns home. My old RGS chapter acquired guns locally, and the store in question provided someone to take care of all of that for us. Worked quite well.
