Hello King. No problem at all with the "Uberti Chamber", as long as you have the proper CH4D dies. Actually the larger chamber works out well for me since I use a 100 % load density with Surplus 4831 under 360 grain LBT bullets for hunting. For Cody Dixon competition, I use MP5744 with the same bullets loaded to a nice mild 1050 fps. I would suggest getting a Lee FCD to allow you to crimp anywhere you need to on the bullet to achieve optimum OAL.
Price sounds fair, assuming, of course the gun is in good shape. As I recall I paid about that for mine with dies (CH4D and Lyman sets) and 75+ pieces of new Jamison brass.
