Fondling fine craftsmanship in your hands and ogling the exquisite lines of a rifle is very stimulating! You have a few thresholds to consider:

Recoil

Hunt Price

I've always wanted a 2fer...

Firearm Price

Having had sales experience I can hear the salesman schmoozing you. You've got a lot of sound advice in this thread to heed.

Listen to the forum friends. You can probably leverage your money around and hunt the game you really want while you are in Africa.

Listen to your body. Invest in ammo and the gun you know that you know that you know that you can put the round in the kill zone.

I can certainly relate to your passion for a new rifle. If it's for one hunt you will probably be better served with a used rifle or just borrow one. Don't fall for the subtle serpent's spell that you just have to have 2 barrels for one shot kills. Let the Professional carry the biggest stick and do the back up for safety. If you have the hunt of a lifetime with your .375 then you can continue saving for another rifle and perhaps hunt in the future.

Listen to your bank account. Patiently wait for the firearm that will satisfy your hunt and needs. You have showed good discipline to save and wait. Persevere and the reward will be worth it, but perhaps for a hunt later on.

Having considered it all, IMHO, you probably already have the rifle for your hunt so get the ammo squared away and remember that perfect practice makes perfect. Then go hunting and enjoy it.

Best regards,
