So, in contrast, I’ve been trialling the Geco Zero 136gr now since this thread prompted me to try something else. Wowzers. What a difference. Knockdown is incredible, wound channel decisive, bullet is designed so the front half splits into petals which detach creating internal damage and the rear “slug” tunnels through creating a wound channel and exit. This was recovered from under the skin of a 140kg (larder weight) stag, the rear section retained 92.5gr of its original 136gr weight, most others have exited with a tiny exit wound but with plenty of organ damage. No bruising or meat damage. Seems to be literally the perfect round.
