Airguns come after powder burners and fishing. I have way more invested in reloading gear alone than in airguns. My rifles generally cost more than my BSA Lonestar did. Not to mention what I have invested in rifle scopes. The big game hunting is typically long range here in central Montana. Knowing where the bullet is going to land at 300 yards or more on a windy day is necessary. One day at long range practice sees me spending much more in reloading supplies than I spend all year in pellets. One high quality bullet, powder and primer will cost in the neighborhood of one dollar, and that's if you do it yourself. Factory new ammo equal to what I reload goes for $2 to $3 per each round, or $4 if it's Nosler. I spent part of yesterday scouting for Elk sign, and I found some, but that is also costly in time and effort. Plus, fishing season on the Musselshell is about to begin, and I need a new canoe...............
More likely that I would "hit a wall" with the powder burners or fishing scenarios, but the airgun thing is mostly a periodic diversion away from those activities, so not very likely to ever happen. I also have a KLR650 that gives me urges to spend a day cruising our country backroads on nice weather days. I have a few other hobbies besides these, and my dog died and I need another dog soon. And quite a few other things that need attention as well. The secret of not getting burned out on anything is to spread your time among several things.
