I have a 2022 Mustang GT California Special Edition and I can definitely relate to the "having money in the bank" reference you speak of. Speed kills in the wrong hands but speed thrills me every day I fire up the beast and tool my way to the office knowing there are few cars on the road with the power and speed I have. Passing someone that's poking along is a pure adrenaline rush and that Mustang exhaust note is pure sweet music to me.

Having said that I used to be a one of those guys that believed in "bringing enough gun" but as I age I find that I delight in my lightweight Model Sevens and my favorite is a Model Seven AWR II in 308. It's a thing of beauty and it shoots every factory and hand load I've ever put in it under an inch with some of them in the 5/8" groups.
We run deer with hounds here in NW Florida sometimes and having a very light carbine with a 20" barrel is a pure pleasure to handle. Most of my shots are under 125yds so it's plenty for me.
If I'm still hunting I usually reach for one of my 7mm SAUMS and if I get another trip out west for an elk or bear my 300SAUM will get the nod backed up by my 375H&H.
Gone are the days when I used a Weatherby Mark 10 in 30-378 or my Model Seven in 350 Rem Mag... The punishment on my end of the shot diminished the fun to the point where I had to work to prevent flinching and that work was no fun any more.
