Cayugad's Original DISC @ the farm

sabotloader · 06-26-2010, 12:35 PM

A couple of weeks ago I asked Dave if I could borrow his Knight Original DISC to get some measurments. I am not convinced that the Lehigh Gen II plug will not work in the majority of those guns also. I believe that Tony Knight was still in charge during the Original DISC run so I believe the manufacturer tolerances my be tighter. The bolts will be more uniform and I think that the barreled action from GM would also be tighter than later runs.

Problem one of our members has one that does not seem to follow my thoughts. 'jsteurrys' has one that seems to fall outside the range.

When I got Dave's the first thing I did was install the Lehigh parts - ran it out in the garage and shot a handful of primers. W209's worked great.

Today I decided to make the time to go shoot the gun. Dave had mailed it to me without a scope, I told him I could just drop on a scope and run to the range with it. So I mounted the Powder Horn on his Weaver bases and head out.

That short barreld Camo/Blued Original is a really good shooter. It would/could be a lot better for me but it is not my gun to tinker with. One thing the Warne mounts on top of his Weaver mounts was to high for me. I fashioned a 'comb' left out of some foam rubber insulation I had here but I still was not comfortable on the scope. The second thing - that got me once in awhile was 'trigger creep'. Course that is adjustable but again - not going to mess with another guys trigger. It is all a motter of getting use to the gun.

Took 3 shots @ 25 yards with it. Shot some Lehigh .452/250 grain HP and thought i was darn good!

Moved the target to 50 and decided I had wasted enough Lehigh's so switched over to my favorite paper bullet - Speer Gold Dots - did not do as well @ 50 - but OK for a new to me gun.

Then 75 yards - I really got to thinking about the trigger pull to much and shots 9 & 11 show the results. One of Semi's rules applies here I am sure... But I pulled it all back together with shot 12..

Here is the target....

And here are some additional pictures. The Lehigh functioned great - clean-up is going to be a snap...

I can't get over how clean that thing stayed. Although with the orange primer jackets the floor of the breech got dirty but the scope stayed pretty clean. Also that is some good shooting. I should have told you that thing really likes powder. I normally shoot 110 grains. But that stock is really able to eat recoil as you might have noticed. For such a light rifle, it handles well.

How easy did the plug come out? You put it in snug I am guessing? And there sure does not seem to be fouling on it.

Seems that is the current thought, and since it is not my gun - decided I had better get started....

Started in the breech area.... Removed the bolt, very little fouling on the bolt. It will be a snap to clean.

Removed the Lehigh BP and as you can see not much to cleaning on it either. You can see that a blow-back free seal was achieved with the teflon tape. The BP had been installed with a socket and ratchet to the snug position. The 'vent liner' turned easily out of the business end of the BP and will also be pretty easy to clean. The plug did require a little more pressure on the ratchet than what I put it in with - but once popped it backed out very easily.

The picture of the receiver floor shows very little fouling in that area also. One windex patch cleaned the receiver floor and a breech brush removed the old teflon tape caught in the barrel plug threads. I then ran a fiber bore brush in the breech thread area to clean the threads to the metal.

Barrel bore - 2 windex patches and a Hoppes patch that came out clean cleaned up the barrel. But I will now complete cleaning and lubricating the bore, before sending ot back to Dave.

Here are some pictures of what I found...

Those of you that have followed the development of the Lehigh Gen II plug know that the primer shelf in the plug is set at 0.195" deep and for most Knights that is an excellent number. In my guns and in this particular DISC Original - if the primer shelf were set at 0.190" - it would be a perfect to snug seal on W209's and Fed 209A's. That would eliminate all BP blow-back. BUT! because of the tolerance differences in the Knight bolts and even the barreld action - 0.195" seems to be the better all around measurement.

Great report.

That is very impressive... thanks much.

No! I wasn't planning on it anyway. I really need to think some seriously about the collection!

Dave,

When you get the gun back be sure and try the trigger a couple of times. I measured it at 2.9 lbs - no creep. It might be to light for you but give it a try....

cayugad · 06-27-2010, 06:42 PM

That will be fine... I will put it through a good range session and see if it still makes me smile. Thanks for the trigger adjustment.
