I would say that a north west gun would be easier.
Some things also to remembers .
1) purchase one of the building books . Myself I like Recreating the American longrifle By Shumway . While its an older book it has all that you will need .
Many folks are recommending for those starting out in building The Gunsmith of Grenville County .
They say its alittle more self explanatory as it has color photos and such . However I myself learned to build long ago using shumways book .
2) these kits are not production kits . These are builders kits and even though they sell them as pre-inlet , they are not finish inlet . You will still need to finish inletting the barrel, lock trigger guards, side plates , drill and tap for all bolts and screws . Solder on barrel lugs front sights or in the case of many rifles cut dove tails .
So you may want to pay to have the barrel lugs done .
3) there is even in a pre carved stock , a lot of wood to be removed before you can get to the finishing as well .
My best advice to you is before you purchase the rifle , buy the book . Read through it a couple times . Before tackling your rifle.
Also if you chose to purchase through track of the wolf , have them confirm that ALL again I said CONFERM that ” ALL” your parts are in stock ..
Nothing is more infuriating then to open the box and find the stock or barrel missing with a back order note saying sorry for your luck . Then only to find when you call for a delivery date that they don’t have one or worse have them give you one only to find that it keeps getting pushed back .
Track sells a fair product but over the last few years I have stopped purchasing kits from them because of that very problem ..
Basicly what I order from Tow is just parts IE locks , bolts some brass and such .
I would also say don’t fall for their 250 to 300 dollar stocks . You can get better grades cheaper through pecatonica river .
I would also recommend that you join one of the forums that have a section dedicated to specifically traditional muzzleloader research and building
I would recommend either the
Traditional Muzzleloading Association
www.traditionalmuzzleloadingassociation.comOR
The American long rifles .com
http://www.americanlongrifles.com.
Both have very good quality builders forums with high volumes of traffic with folks that are willing to help you when you get stuck or just need an answer to something .
Personally , the TMA is more down to earth , with folks willing to walk you through step by step or answer the same questions again and again without advising one to do a search of their data base .
but there is no doubt of the quality of builder on the American long rifle site either. Some pretty well know folks over there
Above all remember have fun , don’t rush and you will end up with a piece you will treasure
