Yesterday the Harvester sabot arrived from Graf. This morning i took them and other stuff up into the hills. The temperature was about 62 when the shoot started, and 67 at the finish. The air was perfectly still; elevation was about 4700'. Target was set out, and the range was exactly 200 yard according to the laser rangefinder. Load was 125g BH209, 200g SST, Harvester smooth sabot, W209 primer. First five shots from a cold clean barrel were some disappointing. It didn't seem i was able to relax.

I gave self a lecture, and changed targets for 3 more shots. These shots i tried as hard as i could, to relax. They were taken at the top target. Knowing there was no way the fourth shot would be good, i quit shooting, and photographed the target.



Then i returned to shoot more; this time the range was 201 yard. The first shot taken upon recommencing to shoot, the fourth shot, was the upper left hole. Shot 4 more times at the upper target. The seventh shot was the upper rightest shot. The 5 shots in the lower target were the first five shots from 200 yard. My shooting lacks precision, but i think the rifle is shooting pretty good now.



I think 3 things have made the rifle shoot better, than it did when new.

1. Cutting some plastic from the end of the stock so it quit contacting the barrel.

2. 108 shots taken may have kinda 'broken' in the rifle, so it shoots better.

3. Tape was put on the stock just ahead of the lug to make contact with the barrel; this may have helped, or perhaps not.
















The bolt, and chingadero have seen 108 shots, and never have been really cleaned. They are clean without being cleaned. This rifle with this set-up has zero blow back. The breech plug has 20 shots since it was last cleaned. It was installed with teflon tape, and it also stays super clean. The flash hole was 0.031" when new. Now the flash hole is 0.035".

Thats some pretty fast flash hole erosion for a vent liner that is suppose to be the hardest. Too bad they brazed it in making replacement $50 instead of $5. Maybe Knight should reconsider and leave it as it was origionally designed??

Lol....I won't comment on this one. Let the other 5000 plus people that have conversions comment.

Wow! that was really quick - I wonder what is going on. I have at least 500 shots through one of my liners and you would be hard pressed to prove it has ever been shot.

Keep monitoring it I wonder how far it might go - but so far none of mine have shown the errosion.

I have both conversions. I have not shot the Knight/Lehigh plug yet however when I first got it the vent liner appears different. Hard to examine though since it will not come out. Just my observations.

I do wonder what, if any differences there might be. I will try to get some information from Dave or even Gordy if I can get through to them...

Actually Ron, you as the consumer might email Knight and ask what might be up with the new product?

I think if you call them they will replace it if it is erroding that fast. Those ones you made out of the Stainless Steel that Grouse considers soft will not errode like that!

I don't judge myself how hard or how soft a metal is. I ask the people who make it. Actually even people in foreign countries as well.

.035 is not by any means wore out for any BP substitute. I do believe Western Powders preaches that you need .035. I like .031 to .033 myself. I have never seen a any disc Elite shoot that bad. I think he should send the whole gun back to Knight to check out myself. He could not get that gun to shoot from day one.

BTW- Hey Mike, he said no blow back and the gun is very clean. As you already know, mission accomplished. A bad vent-liner, plug, or whatever is easy to correct.

I correct myself, if those first two targets are 200yards that's better then i can shoot.

Naw, i am not up for that.

If you think back, you will remember that you are the one that helped me get started modifying breech plug. The success i had, thanks to you, has taken me a ways, and i am not much inclined to ask for help from a manufacturer that sold me a bum product..
