I'm firmly a Whelen guy. I have 2 of them, A Remington Classic, and a JES rebore stainless Remington. Both have done well on black bears. For the first 3 years of my life, I lived near the Frankford Arsenal and had relatives who worked there. Note that Gun Gack 1 describes the arsenal's location as "near Philadelphia". It's actually "in Philadelphia" for those interested in Whelen trivia.
