Ladies and Gents: Hello from CA. First post here as I skipped the "Hello" thread. Great website, WONDERFUL people here willing to impart a TON of free info. Been lurking here for 6 months. Thank you, thank you, thank you! Hunting Limpopo & Free State May 2013. First time. Good bud, his wife, and my wife can't wait to arrive. Trip of a lifetime. Background & Question: I have a Rem 700 BDL that started life out as a 7mm Rem. Mag. THAT'S stamped on the barrel. I like wildcats....had it reamed out to chamber a 300 Win Mag. round necked down to 7mm (300WM/7mm). Ammo is custom stuff made from 300 WM brass headstamp. Obviously barrel caliber and ammo headstamp don't match up. So, am I out of luck to bring my "Hammer of Thor" to my first Safari? I appreciate any advise anyone has re: this issue. Thanks a million in advance. Rick T.
