O.K. I don't use them and never have used them. Please don't kick me off just for asking but has anyone shot anything with these? How'd they hold up, just curious.

What diameter?
I believe Sierra makes them in .338 and .375 both 300 grain bullets.

Sorry, .375.

i shot some long time ago, as i remember it it was typical sierra. accurate as hell, but blows up on game

very accurate and great on whitetail. They seperate cup and core and I would not use them on bigger game.

It's been nearly 20 years so what they were then they may not be now, which was very soft but very accurate. I shot several different animals; Caribou, Moose and deer with them. A buddy killed a Huge Alaskan Moose at about 250 yards and the bullet was under the hide on the off shoulder looking like a silver dollar. Yes DRT. All and all they became a good practice bullet.

I to have used them (300 grain Sierra in 375H&H). They are very accurate in my gun, but I consider them a "plains game" type bullet. For dangerous game I use a 300 grain Swift A-Frame for my soft.

I have used them as well in my .375H&H.

Like everyone else has affirmed, they are very accurate with a number of powders.

Used them on Plains Game in Africa with no issues and have used them quite a bit on Continental Game, too - Red Deer & Wild Boar with good, solid performance. Shot one Roe Deer Buck of about 50 lbs. also; somewhat ovwergunned but like the .375H&H tends to - just poked a .375" hole in him.
