I live on the west side around Goodyear. I love it out here. I moved from Illinois over 10 years ago. Bunch of us old boys go out in the sandbox and shoot long range. From 1,000 yards to a one mile. I don't miss the cold at all.
Go with a good 1911. But don't go with it in the small of back holster. I would stay with a four inch or longer model. Been carrying a Colt Commander or Les Bear Concept VI. By the way I love manual safety. I carry one every day and love it.
I have a Rem 700P 300 Win Mag with a 26'' barrel. Did the one mile with 200 grain SMK. I hold a 4 1/2'' group at 1,000 yards. I use Reload 22 powder. And I'm a old man.
I have to say for a man of your advance years, that's real nice shooting. Best one's was Varget and AA2495. You got two loads working great. About the time the heat cools you well have the other one. Now do your happy dance.
