And expect to bring more than gets shot. If I had to guess, at LEAST half of the firearms brought every year never get fired, or get shot VERY little.
Last few I can think of that were super popular, TennMike's (now defunct ) 50 BMG bolt action, BigAl's M1941 Johnson (His brother in laws ) and my 50 Beowulf normally comes home with quite a few more empties than loaded rounds.
Wambli's 329 also got shot QUITE a bit last year.
Basically, if it's not common, LOUD, or kicks hard, folks will probably gravitate to it. (Ask JBOhio about me and his 300 RUM )
My 6.5 Grendel 799 was fairly popular with some of the new shooters last year too.
