I've used the Remington Lee quite a bit and can say it is a weapon with many fine points. But having used the Kragand the Remingon-Lee, I would take the Krag any day in any situation involving the use of small arms.
The Lee's faults are (worst) an unreliable extractor/ejector, its half-cock bolt plunger safety, and a bolt assembly with tiny parts easy to lose in the field. Its strengths are its extremely strong action, detachable box magazine and light weight.
I could have taken the Lee hunting anytime, and have always taken the Krag instead, even though it weighs a pound ANd a half more, and I won't load it up the way I can with the Lee.
Try both rifles. You'll see what I mean.
