PJ....
I recall someone posted an article quite a while ago on here, that some country in Africa used 308s, with the 220 grain RNs, to cull Rogue Elephants in their country via their Fish & Game people...
Brain shots, from a stopped vehicle or Truck...
had an acquaintence around town here years ago, all he had for a hunting rifle was a H & R Single shot break open in 30/30... he wanted to go bear hunting, but wanted the most thump he could get out of a 30/30 case....
I loaded up some 220 grain RN's, behind like 35 grains of W 748... MV was 2100 fps... it had a kick to it, but the brass never seemed to notice or care....
he was successful with those loads and that rifle for a couple of seasons...
lost track of him, when he moved a few towns away for a job....but he upgraded to a 308 H & R rifle,
and I got him trained on handloading... he sure liked those 220 grain RNs....so I bet he was loading them in that single shot 308 he picked up....
