the 404J is just a DG Rifle plain and simple
The 404 is a dangerous game rifle.
i dont agree with this, the 404 Jeffery was originally designed as a short/medium range PG gun using a 300gr bullet. it fell into a similar class of cartridges as the 9.3x62. i use my 416 RM exclusively as a PG rifle with a 300gr Barnes TSX moving around 2650fps. this is a very effective PG cartridge to about 200 yards and has stopped every game its hit properly in short order.
now the problem with the 404 Jeffery these days is the odd bullet size. your bullet selection is terrible and few manufacturers make any thing but 400gr bullets. however it does look like Peregrine bullets offers some nice 320gr bullets for that 404 Jeffery which should work great on both PG and lion.
