got to have a decent 12 ga. for birds - Remington 11-87 Premier
big rifle for those pesky elk - Remington Sendero in .300 Win magnum
medium rifle for distant deer and antelope on the open prairie - Remington Mtn rifle in .260 rem
long range predator and pd rifle Remington VSSF II - 22-250
Several medium range pd rifles ...various Remingtons and Savages, couple of TC carbines .221, .223s and .204s
Some rimfires- a few of those
and accurate pellet rifle for those covert tree rat adventures
Is that five ?
Those are essential but I fill in all the caliber gaps and such with other guns.
