I have a left hand percussion .50 that I took a nice doe with last weekend.

It's a well-made, accurate rifle. Mine didn't shoot well with light loads but groups very well with 60 - 70 grains of 3Fg under a .490 ball using either a 0.018 or 0.020 patch. I am planning to try conicals in it because I my ball didn't pass through the very large doe I shot on Saturday, so the blood trail was poor.
The rear sight is not great due to some wobble. I removed it and installed a Lyman 57 SML peep sight (required 1 hole to be drilled and tapped). I also replaced the factory front site with a Lyman white bead, which shows up really well in the dim woods. The gun is very similar to the Lyman Trade Rifle and if Investarm had used the same dovetailed rear sight as on the TR I would have kept it.
If the gun is in good shape, especially the bore, it's a good deal at $300 IMO. I prefer it to the T/C Renegade because the stock fits me better and in .50, the Hawken is lighter.
Cabela's no longer sells this rifle but Dixie Gunworks and Muzzle-loaders.com sell it under different names.
