Hello again Heym, and once again thank you for contributing

Yep, i quite like Spoomer, who tends to be a sensible guy, and one who has understood that there is probably a niche for actually speaking honest sense, rather than pushing a certain cartridge, powder or brand in general.
In the end I shall of course have to make my own experiences in the field, but yep, understanding how your given chosen bullet works when it hits the animal a given place, and then being skilled enough to put is there, is key i reckon. Be that with lead or non lead.

And we agree on the petal thing potentially rupturing things, it worries me too, a bit, at least if one doesnt adjust the classic boiler room poi when shooting. But as you say, one can chose to do that, if using bullets like the sonic.
As for your 223 comment, wasnt there a famous gun writer of yesteryear, who had a line about the 220 swift, or was it the 22-250, being the deadliest round he had ever used, barr on bear ?
