back when I 1st got into guns ( my FIL was grooming me to take over his collection ) I was going to buy one handgun, & one rifle, & borrow anything else I might need... my choices back then were a 4" 357 Magnum, & a 243...
I know alot more now a days... 243 would be too light for my "do it all cartridge" today... I do really like these
6.5 X 55
7 X 57
but I'm actually going to be buying another hunting rifle ( stainless ) in 270, only because it is also at least as good as the others, & I inherited a ton of 270 cases & loading components
In life you either make dust or eat dust...
