While looking at rifles at the DSC show last weekend, I noticed a few rifles chambered in 400 H&H. I have to admit to being a little intrigued by this caliber, simply because the name sounds kind of cool. I was told by a vendor that he would choose the 400 H&H hands down over the 416 Rem Mag. He claimed it was much easier to get the advertised velocity from it than it was from the 416 Rem Mag. I thought that sounded kind of strange due to the fact that the 400 H&H has less case capacity than the 416 Rem. I also see no advantage in regards to case taper for reliable feeding and extraction. 411 bullets do offer a VERY slight edge in SD, but are not as readily available as 416 bullets. So what gives? Am I missing something?
