Got me some books from Amazon and their 2-day shipping...
These Ruger Blackhawks are all chambered in .4 - from top to bottom are two 5-1/2" New Model Flat Top .44 Specials (for target and defense). For hunting, a 7-1/2" Old Model Super (those were all .44 Mags) and a 4-5/8" Old Model in .41 Mag
That just warms my heart! Thanks man!
