Thanks Hermano for your info. A year or so ago, we spent a few days in Barcelona while waiting to get on a cruise. It was a lot of fun, even though there was some rioting going on. Beautiful country and lots of things to see. I plan on stripping off the barrel blue and shiny stock finish on the Ardesa this weekend. The wife will be out of town and I won't have honey-do's in the way.Hello. As I live in Spain I can give you some information about that Ardesa replica of the Hawken. That model and also in caliber 50 was the first rifle that I bought in 1988, when I was 25 years old. If it is a 50 caliber, it has a 66" twist. Therefore, it is a good rifle to shoot with a round ball, especially with not very high loads, since the groove is not very deep. At 50 meters it groups very well with 50 grains of black powder. Swiss No. 2 (3fff). Use 0.490 ball and 0.015" linen patch. And trade the rear sight for a semi-buckhorn. Walnut wood is of good quality and if it takes away the shine you can finish it with linseed oil, in a more natural way and with a very beautiful darker color. The nipple is metric thread 6x100. It is a very good heavy rifle for competitions for 50 meters (55 yards) or for hunting, but with a round bullet, because with a maxi bullet I don't think it will group well.
If the nipple does not transmit fire well, you may need to remove the side drum and trim it so that the fire from the nipple communicates well with the breech that closes the barrel. You can also change the side drum for a good quality steel one, like the one you sell for Spanish guns Track of the Wolf (from Dikar-CVA- and Ardesa -Traditions-).
Greetings from Spain.
