Author Topic: Rough barrel (Read 654 times)

I picked up a CVA Stalker 50 cal carbine that wasn't cleaned before storage. The bore is pretty rough does anyone have any tips to smooth it up? Do you have to remove the drum before pulling the breech plug? Can anyone recomend a source for parts or a new barrel if needed? Thank you for any help or information. Paul P.

Hi Paul

,
Do Not attempt to de-breech that rifle

To save money, time and still meet saftey standards. CVA aliens the breech plug with the barrel first, then drills and taps "through" the breech plug threads to install the nipple drum. So, in effect the nipple drum holds the breech in place. During that process, the breech threads are de-formed and if the breech plug is removed, the torn breech threads will shred the barrel threads or vice-vrs,, :cry: follow?

OK, Now, you can remove the drum. And the barrel Can be polished to a certain extent. I've never had a cva fast twist gun, but I have re-furbed a few old slow twist to satisfactory results, thay had/have a deep land-goove set-up that is very forgiving. Don't despair,,

CVA went through many changes in how there breech plugs were set . They even used 3 different type of bolsters/drums and a couple different nipple thread sizes . Its impossible to guess which one you have without looking at your rifle .
Keep in mind the later models also had a machine set breech plug . This means the plug has a taper to it . This is inserted under torque , making it almost impossible to remove with common tools .
Replacement breech plugs and bolsters are available if you chose to replace it through track of the wolf , dixie or any other black powder gun supply shop .
but keep in mind , just as lostid said, the bolster or drum is inserted after the barrel is breeched , there for you have to remove it first .

Myself if the barrel is really bad with deep pitting , I would just replace it with a green mountain or Colerain . Maybe watch e-bay for a replacement that would be in better condition . The other thing would be considering replacing it with a traditions barrel .

Now if its not to bad and just has some mild rust thats making the barrel not as bright as it should be .
I would suggest lapping it .
Take one of them green or brown pads steal wools works as well used to clean of paint found at most auto parts stores in the paint section or even the lighter pot and pan pads.
Fit this to your ram rod and give her 100 passes being sure not to let the patch leave the barrel . One pass = in and out .
You can also use valve grinding compound on a cleaning patch . This works well however if your not careful you can take alittle to much off the edges of the rifling .

The other method is to fire lap or impregnate some patches or the rings of a lead conical with lapping compound and simple shoot a few rounds

Thanks for all the replies. I'll try polishing up the bore before I try to debreech it, if it doesn't clean up too well I'll take it apart. I figure I've got nothing to lose and I might even learn something. Thanks again for all the replies I'll let you know how this works out. Paul P.
