Given my somewhat compulsive nature, I have recently become (more) obsessed with double rifles. However, I have virtually no experience with them so I thought I would pose the questions to people wiser than I. I am not a professional hunter. My use of a double would realistically be used on a Cape Buffalo Daggaboy or a Hippo hunt. The rifle would also just be entertaining to shoot recreationally. I'm looking at several Sabatti rifles. I spent time researching the brand and have seen the good and the bad. I enjoyed the Sabatti rifle thread in this forum. I found it very informative. I found a Sabatti .450 NE O/U with extractors only that seemed interesting. I like the idea of at least one barrel being positively aligned with the sights and a scope if mounted. The lack of auto ejectors concerns me more than the gape needed to reload. I read that thread and it would seem that it isn't a concern unless I've already expended two rounds downrange, failed to stop the threat and need to reload quickly. The price is also noticeably less than a S/S. Opinions? I have also looked at S/S rifles in .450 NE and .450/400 NE. Brass and loaded ammo is readily available through Midway USA for the latter. .450 NE brass is not nearly as common. The .450 brings all of the power I would want with a 500 grain bullet between 2000-2150 fps. The .450/400 with a 400 grain bullet at 2150 fps has less muzzle energy than my .375 Ruger (Ruger Hawkeye African) with a 300 grain bullet at 2550-2600 fps. Has anyone used both on heavy game and does one seem to have more real world effect? I thank everyone who has a constructive opinion and I appreciate the opportunity to learn from you all.
