The 7x57 would be an easy down-load, especially using the 120 NBT. One of my girl cousins has been killing Texas deer/hogs for 40yrs with a Mod 700 BDL 22-250 and 55gr factory soft points. I uesd a 220 Swift a few months before the oryx hunt. I shot the then available Federal factory 55gr trophy Bonded Bearclaw bullets. I killed an axis doe and two nice Blackbucks. Wicked killer. A 22-250 is easier to find great ammo for. You can pop crows/varmints in the off seasons and kill deer/hogs in the Fall/winter. Before brass got so hard to find, I played with a .224 Texas Trophy Hunter, fast twist. It is the 6mm Remington ( 7x57 case itself!) necked down to .224. I used the 64gr WW for varmints/plinking and the Swift 75gr Scirocco on a 300#+ hog ( neck shot). A standard 22-250 and 55gr Barnes would have done the same! Good luck to you pard and remember, my Sr Class HS girlfriend won "Miss Dogwood Festival" in Woodville, Tx in 1970! ha
