More questions I'm afraid. I am off to Africa in October to hunt some plains game and also a crocodile and a hippo. I have a Ruger single shot .30-06 in South Africa with my PH already so I need to take ammo for that. I am thinking about some custom ammo, 220 grain Nosler partitions or normal Federal 180 grain Nosler partition for the antelope/zebra. I MAY have bought a .470 NE in the next month or two which has been regulated for Federal factory ammo I believe. Assuming this is a 500 grain bullet at approx 2100 fps if I get Stars and Stripes in the US to build some custom ammo for me with both A square monolithics and Dead tough softs to the same specs would it be fair to say they will group pretty close. I am only interested out to 75 yds or so, the rifle will be a back up. I ask before I go ahead and order up the ammo (if I have bought the rifle) I was worried as I had heard stories about these A square bullets damaging the barrels of doubles but the chap at stars and Stripes said he has offered a "reward" for anyone who could send him a picture/X-ray proving this to be the case. all thoughts welcome and thanks in advance, Mike Bailey
