RE: Looking for a BP around $250
The Knight Revolution I so not know that much about. I talked to a person that bought one and he said it shot real accurate, but did not alway ignite the 209 primer and was going to send it back to Knight. Whether it was fixed to his satisfaction, I have not checked back with him.
The Knight Disc is a bolt action style rifle. I own one. It is a good shooting well made rifle, capabile of some impressive accuracy. Besides the Disc there is the Disc Elite, and Disc Extreme. All of them are some of the best shooting rifles I think Knight made.
The Black Diamond by Thompson Center is a real nice rifle. It has a free floating barrel. 1:28 twist, handles all three ignition systems.. #11, musket, or 209 primer. They are a very well balanced and excellent shooting rifle. I own one and they will really impress you. They are a hammer/striker model rifle, so they are open breech, but I would not let that worry me. For a hunting rifle, this one will get the job done.
I do not own a Kodiak, but have read some impressive posts on their accuracy and the way they handle. I am sure some of the Kodiak owners will commment more about them for you.
Check your local Wal mart and do some google on the different models. On some of the auction sites they can be got pretty reasonable...
