I choose from my options depending on what game I am after and what terrain I will be in. Plenty of calibers and brands to choose from, Remingtons in 25-06 , .270, 270WSM, 35 Rem, 20ga, 12ga, Rugers in .223, .243, 7.62x39, 30-06, 300WM, S&W in .308, Marlin in 35Rem, Savage in .223,along with plenty of .22 options and the ones I forgot. They pretty much take care of all my needs...
