Is this gun for deer, target, or what? I'm assuming for deer, so I'll tell you the gun is fine as long as you don't expect to drop a ten pointer at 100 yards. They are good guns for 30-40 yard shots and even a little farther. If you buy the gun, be sure to take it to the range and find out how it will perform at 50 yards. Also, you'll want to experiment with loads and projectiles. I still shoot my .50 cal T/C Hawken with 100 gr of powder and a ball 'n' patch. Does a fine job for me.
I do have to agree with Tommy that a couple of twenties more will let you reach out and touch at greater distance.
