I think I can answer that question for you, it's been discussed here and elsewhere.In my younger years i lost a few because i flinched from 7mm RM recoil. Im done with magnums.
I also brought my .243w with 95 NBT and 108 Berger elites. Tempted to try the bergers to see what it does.
@form
could you shed some light on my last post related to the no blood at all "issue".
The truth is that while I think 77 gr TMK has shown itself pretty well to be a robust killer of most North American game provided decent shot placement, it can't be relied upon to exit consistently and even when it does, it can't be relied upon to produce a blood trail consistently.
For most people this probably doesn't override considerations like recoil, weight, platform benefits, etc. Most people probably wouldn't be using a bullet that consistently produces a blood trail regardless.
For some people this aspect of bullet performance may be very important, especially in dense brush. Sad to say but in these cases 77 gr TMK, or really just about any .223, is probably not the optimal choice.
At the end of the day smaller calibers are still less powerful and have less horsepower to work with than larger calibers. For the purposes of simple, nominal lethality, this isn't usually a practical limitation for most game at most ranges. But if you want the bullet to do some other things beyond just kill quickly with good shot placement, you're going to run into issues.
