guess I think of it a bit different. Id ask why use something marginal. . . . . 
Oh I've never used anything marginal. 
It's more like other people would consider 
them marginal. 
I can remember one of the trips we made some 
years ago to one of the places we used to get to 
cull hunt. One of the other employees at my job 
was ragging me for carrying a Marlin 30/30, and 
was carrying on about the wounded deer, how 
it would drop past 100 yards, blah blah blah etc. 
The buddy I went with carried his oldest son for 
his first hunt and used a single shot 30/30 that 
had belonged to me. We used my handloads
( back when it was actually cheap) and I tagged 
out with 5 deer for 5 shots, and him and his son 
brought back 4 , one of which was the boy's 1st
deer, killed with 1 shot each. 
The other people on the lease that weekend 
were more "appropriately " armed with all
identical 270's and premium federal ammunition. 
Either 6 or 7 of them, and they took 1 deer with 
however many a browning stalker 270 holds 
plus a reload. 
You have to know how to kill an animal. 
That's why I always say that an apocalypse 
won't kill off the game. Even in relatively 
ideal conditions not everybody with even
top drawer equipment can make meat. 
I got a squirrel for stew today with a 110 bg
trap and didn't fire a shot
