Specifically the performance of Berger 168gr VLD as compared to the 125 grain Sierra prohunters.

Would reasonably expect the same sort of term of terminal performance as of something like a light for calibre conventional soft point.

Leaving aside the ballistics for a moment, should one be as wary of bones and angles with the one as the other?

I only have one hunting experience with a Berger bullet. My was a 190 gr from my 300 WM vs a 250 lb pig. It was a hard quartering shot behind the ribs on the right side and it ended up on the inside of the left jaw bone. Terrific penetration and a dramatic DRT kill. The bullet held together very well.

Wow, thanks 450, that's certainly taken the wind out my sails....

What sort of velocity were you pushing them out at sir?

2,900 fps

What were you hoping for? It's just one example...I'm sure someone else will post that they've shot a fox and were disappointed that they didn't get full penetration.

Well not quite, it's a little difficult for me to articulate but basically when someone says that bullet x is too soft but bullet y is fine I have a bit of a hard time working out exactly what they mean because by it's very nature, such a comment is a subjective one. I might not know what their frames of reference are for hard (are we talking Hornady Interbond hard or TTBC hard?) and so on. The second is that I might have shot bullet x but thought it was fine because the animals I shoot are smaller and softer than the animals another guy shoots forcing me, this is the internet afterall, to denounce him as a crackpot, put him on ignore and stalk him on photobucket.

Now, if someone was to tell me that in their experience bullet x is softer than bullet y, if I have used either of those bullets myself I might stand a better chance of knowing where things stand on a relative, though still subjective, scale. For example my boat tail speers do fine on UK deer which are quite soft compared to say African antelopes of similar size. If someone says that bullet y is softer in their experience than the Speer I can be reasonably confident as I know they have shot whatever it is they shoot with both and bullet y was more frangible.

So the point of the question, I think, is those guys that have used say a 168 gr berger, which I have and am not really 100% happy with except for in the circumstances I gave in my reply to ScottfromDallas's thread on Bergers, have any of those guys used a 125gr Sierra and how do the terminal ballistics compare.

It could very well be a nonsensical question, now that I read it back to myself...
