Cordless is the way to go, on job sites with multiple trades working at the same time they're no mountains of cords to trip over, save a lot of time at the beginning and end of the day rolling up cords. Buy a good brand, with the bigger batteries. I use a grinder with a masonry blade for cutting brick and block, way easier than starting a gas saw every time you need a cut.
That looks like it would be an awesome turkey gun, short, light, I wouldn't feel under gunned with a 20ga, I would definitely spring for the TSS shells, they're deadly.
In 2000, my Dad gave me 77-22 mag for my birthday, I have a 3x9 compact Burris on it. Really cool gun, but like you said, the triggers suck. Shot my first Coyote with. I have 77's in 7 mag, 22 mag, and recently bought one in 243.
I bought a blued wood stock Ruger 77 in 243 last week off one of my buddies, he bought it just for the gloss Leupold scope. Nice looking Gun, I have a gloss 6X I'm putting on it.
I had something cut out of my leg 2 years ago, couldn't believe the size of the cut, I didn't feel a thing. I go to the dermatologist twice a years, alway get spots burned of with liquid nitrogen. Fun stuff
