Well, I'll throw my $0.02 in.
1. False, I have never seen one type of rifle inherently better than another, it is usually the shooter.
2. I don't hunt, I only target shoot, so I would rarely attempt a shot over 150, but that said, I have shot a winchester model 94 30-30 at 225 and had good results.
3. My main leveraction is a Henry rifle. I will stick with flat nose bullets thank you. I wouldn't feel comfortable sliding anything down the receiver on top of a pointed end.
4. I have heard this as well, I am post 64, so and have a 30-30 from the 80s that is very sweet.
5. I have never shot a trapper rifle, but I have shot an 1860 Colt Army, with an attached shoulder stock. It has an 8" barrel. At ~75 yards, off shoulder, it was equal to the afore mentioned Henry Rifle. You can take that with a grain of salt as it was my shoulder, but I got 2.5" groups out of both. That makes me happy.
