Cabelas' site is a good reference point. However, you may wish to shop around for better prices on the same items.
For example, a box of (20 bullets) Hornady SST-ML Low Drag High Speed will cost about $17/box before taxes at Le Baron. I mention this bullet as it has performed very well in my TC as well as a CVA Optima rifle that I had tested. The bullet is comparatively far easier to load as it is a .45 cal bullet encapsulated in a 50 sabot. Admittedly, I haven`t had an opportunity yet to validate the bullet`s terminal performance on game yet - perhaps this season .....
Another example, a 10oz bottle of Blackhorn 209 powder is priced higher at Cabelas. BH209 is a bit pricey but the small bottle contains enough powder that allowed me to experiment with different powder volumes in order to determine best powder charge/bullet combo for my rifle. I believe I still have aprox half of the powder left that will likely last a few deer seasons provided I don`t expend that at the range. I mention this powder specifically as the product definitely enhances the accuracy potential and greatly facilitates ease of re-loading as well as simplifies cleaning just with oil based solvents (designed for smokeless firearms) such as Hoppes etc.
Likewise, a box of primers (100 pcs/box) will last a while. Note - should you decide to go with BH209 powder then the specific primer(s) to use in conjunction would be either CCI 209M or Federal 209A. Cabelas`site (mistakenly) refers to the use of standard CCI primers with this powder.
Obviously, a few additional/necessary accessories will be required as part of your initial investment. However, those wil generally be low cost affairs.
Good luck with your quest.
