you can't really have many issues with H4831 or IMR 4831 but I prefer the 150 grain speer bullets in a 270 win.
btw Ive also used a speer 200 grain bullet over a stiff load of H4831 in a 30/06 browning BAR,
with a 215 federal primer, on mule deer, it no more or less lethal, and it kicks a bit harder but , I'll point out its also been a consistently accurate combo!
most of these discussions are rather pointless as its the skill of the user and his knowledge ,and acceptance of,of each rifles accuracy and range limitations, and the projectile selected, rather than the cartridge that makes or breaks the combos effective use!
the one attribute it does seem to have is its use
(200 grain bullet/300 win mag/ BAR) irks my hunting buddies,
if I use it on mule deer, but not so much on elk,
I find it amusing, and a bit confusing, in that I don't really understand why my choice in rifle or handload combos,
can in any way effect them. but if you lack a reason to start a heated and pointless conversation, tell the guy next to you you have a 300 win mag in a bar you intend to use on mule deer hunts..... its always resulted in a pointless and sometimes mildly heated discussion... I don't really know why, it works well, and if you place shots in the lower,. heart/lungs its been very consistent/lethal and does not destroy any more meat than the 270 150 grain combo does in my experience.
