I would choose the Knight KRB unless I absolutely wanted to shoot the new Blackhorn 209 powder. I would also hesitate to recommend the KRB to someone that strictly wanted to use open sights, not because of the sights but because of the stock design - it's pretty much designed for a scope as you have to really scrunch down to use the irons. I have not had the best of luck with my Knight KP1 (VERY early production) but I think it is another you should consider. Another owner recently posted excellent performance using BH209 in his KP1. The KP1 is also a bit lighter than the KRB and is easier to prime (IMHO).

The Triumph is getting some great owner reviews and fires the new powder nicely. I don't like the TC Omega/Triumph for two reasons - QLA is a big negative in my book and the trigger guard area is quite small on both rifles - too small for me.

Lots of people use Trijicon (or similar) on their inlines with good results. Recoil depends upon rifle and load. The Triumph is a kicker with heavy loads. The KRB or the KP1 would handle recoil better. Stout loads in a Triumph would probably exceed the recoil of a typical '06, while being less in the heavier rifles such as are the Knights.

There are other options aside from 100 or 150 grains, even using pellets. I prefer loose powder for reasons of economy and the ability to tune loads down to the grain. I think everyone should start with loose and then have basis for comparison of a few pellets. 100 grains of most any powder behind most any reasonable bullet weight will kill most anything that walks this planet. Please do NOT start muzzleloading thinking two or three pellets and a Powerbelt are the ticket to success.

You will NOT get 30-06 performance from any non-smokeless muzzleloader. Sabot bullets are available in the 200 to 300 grain weight range that perform very well. The Parker bullets are repeatedly bragged upon as among the best ( http://www.parkerproductionsinc.com/) although there are lots of bullets that do very well for less money. Good ol' Hornady XTPs can be hard to beat in the sabot world. I prefer to cast my own heavy conicals which I use for both target and hunting (except in my Contender G2). There is almost no end to bullet selection in muzzleloading. Hornady may soon sell some bulk bullets of the SST flavor that should be a great choise.

Knight KP1, Knight-Talley scope base/rings combo ( http://www.budsgunshop.com/catalog/product_info.php/manufacturers_id/102/products_id/53726), perhaps a different scope as I'm not sure a Trijicon would mount in those (Leupold 2x7 would be great), a couple of containers of BH209, some of those Parker Ballistic Extremes, some Winchester or CCI 209 primers... should be a fine start.

There there is all the other "stuff" you will need for cleaning but it won't be nearly as much with the above combo as it would be with others. I do strongly recommend a good, solid range rod be included from the start.
