I'd recommend the GS Custom flat nosed monolithic solid. It's fine for doubles and they penetrate like you couldn't believe...... and they have an agent in the US.

Their website is: http://www.gscustom.co.za/

I've never been there but have seen all their training videos etc, seen the syllabus' and spoken to others who have been there and nor do I know where you're located but if you're anywhere near Dallas Texas, you might like to consider a visit here: http://www.ftwoutfitters.com/Fliers/SAAM_Safari.pdf.
these courses look to be the closest thing to Africa, outside Africa and even if you're an experienced African hunter, I reckon it's well worth a visit.


Have you swept the visioned valley with the green stream streaking though it?
Searched the vastness for a something you have lost?
Have you strung your soul to silence? Then for God's sake go and do it
Hear the challenge, learn the lesson, pay the cost
