Andy,
I use a custom left handed longbow made by Jim Brackenberry. (Best known for his recurves.)
50 pound draw at 28 inches and it's as sweet and smooth as anything I've ever shot.
Scot,
I've been involved in Archery since I was about 8 years old. (about 32 years ago.) I started out with the famous Bear "Cub." A red fiberglass 10 pound recurve and worked up from there.
Shooting a bow is an easy thing to learn, it only takes a couple things.
1. Time
2. Effort
A Coach who knows what he's doing and how to teach it never hurts either.
Your definition of "reasonable accuracy" is pretty stiff.
50 yards is extreme distance for any bow, and beyond the responsible hunting range of all but the most powerful compounds in the hands of the most experienced archers. Reguardless of what bow I'm carrying, 40 yards is the maximum distance I'll consider shooting at, and even then I'd only take a perfectly set up shot with a perfectly tuned compound. If the arrow's not doing at least 300 FPS when it leaves the bow, forget about taking this shot.
A few of us in my club used to shoot at extreme range on 3D targets just for "braggin rights" and we'd go all the way out to 65 and 70 yards and I once had a 68 yard shot at the Ben Pearson Memorial Shoot, but it's not normal and you sure wouldn't want to stick a deer at those ranges, it would just be irresponsible. A perfect hit wouldn't have enough energy to reliably down the animal.
Try this for a "reasonable" accuracy definition.
If you can put 120 arrows in a row inside a 1 inch circle at 20 yards, you may be next year's National Indoor Archery Champion.
That's how big the X-ring is on the "5-Spot" Indoor Archery target.
Drop one out of the X-Ring though, and you're out of the running.
The last competition I shot was the Arkansas Indoor Championships back in 98. I was looking very good for taking home a nice "dust collector" right up until the moment when I blew my shoulder out. My wife managed to bring home a State Championship for her division though!
Because of the shoulder injury, I just can't stand to shoot 120 flights in a day and still keep the accuracy needed to be competitive, so now I just shoot for myself.
Which is easiest to learn?
Hmmmm....
Tough call. It depends largely on what you're looking for.
You can go spend a lot of money at the local Archery shop and be outshooting most Traditional Shooters in a month or two. Only problem is, you'll be using a lot of gadgets, gizmos, and geegaws to do it and you'll eventually have to learn how to tune all that stuff yourself or start signing your paychecks over to the "Pro" at the Archery shop.
The other route, is buy yourself a GOOD Traditional bow and spend half an hour every night after work shooting.
Shooting traditional you'll need to buy a few things
1. A bow
2. Two strings (always have a spare set up and ready)
3. A leather arm guard (Don't forget this one, you'll need it!)
4. A dozen arrows
5. A target
Buy a good "arrow stop" target and don't bat an eye at spending 100 bucks on it. The money it will save you in damaged arrows will make it pay for itself very quickly.
Learning to shoot your bow is a matter of time and practice. Fortunately, it's FUN! You don't have to spend hours every day, just make sure you shoot a litte EVERY DAY!
This will allow you to learn your bow and teach you to become a good instinctive shooter. (What all Traditional Archers want to be!)
Start at 10 yards and when you get a nice cluster of arrows in the target, move back a little farther and start all over again. Before you know it, you'll be busting your target at 30 yards and MORE than ready to go deer hunting!
