I posted this in another thread recently, but it answers your question and is backed up with a lot of actual experiences in the field.
I've shot hundreds of game animals (in excess of 500 now) with the 7mm 180 Bergers at muzzle velocities of 3200 fps up to 3460 fps, at ranges out to 1425 yards. Until recent testing of the Wildcat alloy tip 338 projectiles that are now no longer available, the Bergers have been the best killing longrange projectile available. I'm talking 180gn moly bergers from a large order I made maybe 10 years ago that I'm still using, so with the original jacket thickness.
This is on Sika and Red deer, and Himalayan Tahr and Chamois. These game animals run from Whitail size up to almost Elk size for comparison.
The 180 Berger has consistently expanded at ranges over 1000 yards and nothing else I've tried has. (Other than unavailable Wildcats) I have yet to have a failure up close with them either, but haven't had to use them on a bad angle on a big animal yet, I use mainly AB's for that application.
I was pleased they held together at 3460fps, but have had no problems at all and grouping superbly. This is out of a 9" twist 30" Lilja. The G1 BC (not that we should be talking these anymore!) averaged .74 to 1000 yards. Run those numbers, pretty impressive ballistics!
I have some 189 Caut's to try in some Broughton 8" twist canted lands that don't like the Bergers as much, but haven't shot them at longrange yet. These Broughton's love the 200gn Wildcats accuracy wise, but ballistically the 180gn Berger's way faster velocity is better out of my barrels.
