As of the past year or so the one gun that always follows me to the range is my 7 1/2" SBH hunter in 44 mag. My load of choice changes with my mood but it's usually either a 255 gr cast bullet over 9 gr of unique or 22 gr of 4227. If I'm feeling frisky, or just want to relieve some anger, my full house fire breathing load of.... well I'm not gonna list the charge here but we'll just say it's a few grains over max listed load of H-110/296 under a hand poured 310 gr bullet. That one always puts a smile on my face.
While I am starting to amass a small collection (wife doesn't think it is small), the gun I enjoy shooting the most would probably be my Les Baer Thunder Ranch Special. Everyone I let shoot that gun falls in love with it. It is an absolute tack driver and the trigger is amazing. I just got a new Sig P210 Legend that I hope will fight to be my favorite gun to shoot.
this will sound silly to some that are all preaching the pricey pieces, my favorite pistol to shoot is the Tri-Star t100. love it, wish I could carry it.
