Home Forums Hunting & Shooting Muzzleloaders doesn't feel right

i would say that if they were , it would have to have been late Hawkins rifles , produced under the Hawkins name after they sold the shop .
i say that because the rifling platform they had , seems to me to have been incapable of drawing cut rifling through a tapered bore .
It is often recorded that Hawkens rifles carried a tapered barrel . But that�s the profile of the outside not the bore
Now I could be wrong but the taper bore /squeeze bore didn�t come about until the advent of forged rifling
Now I have heard of later bench rifles with a tapered bore but normally that was only .0001-2 at the muzzle area .

could you PM me with refrance to Hawkins rifles and the taperd bore big block . i would engoy reading about that

I would seriously doubt that Adesa is using a MIM process for barrel manufacturing .
If they were , their parts would have much higher tolerances. Which swampman , you are saying they don�t
But again if we are to complain about what Adesa does , then why not complain about what S&W does ???
Or Remington for that mater .

The fact simply is that if you have a modern gun , that gun will most likely have MIM parts . doesn�t mater the maker .
In fact many older guns have early MIM type parts .
I remember back in the early 80�s when many manufactures started selling injection cast parts .
Specifically breech plugs . OHHH how the cry went out about how unsafe they were .
Yet today , its not uncommon to find a very large selection of injection cast plugs .
This cry about MIM is IMO nothing more then the old cry about cast vs. forged parts
In fact I would seriously doubt that for those who buy complete finished replacement parts, you would know if the part was originally injected molded or not unless someone told you .

The difference you are talking about is that today MIM also includes binders vs. the old complete metal melt . Its also a completely different process that�s primarily used for making parts that would other wise have a very high production cost OR a lot of milling cost . Again production cost . That�s where the MIM production comes in and frankly where it shines
Despite what you may think , barrel making is not such an area . Yes it takes time but what�s been the major cost is in the rifling of the barrel . But today as more and more barrel makers switch to the button rifling process , which now takes around 60 seconds to rifle a bore vs. cut rifling which even with modern machinery still takes around an hour . By hand , days .
I would bet that Adesa uses the button rifling process as its been accepted in Europe for some time, where we have held onto the cut rifling

I do think the day will come when modern MIM enters the rifle barrel market .
Some suggest that its already in the pistol barrel market ,. But frankly you�re the first I have heard suggest that someone is already using MIM to make rifle barrels.
