Change the Endeavor 2 days before season
 

Took the Endeavor down and add a +.001 pivot pin, while I had it down I took out the ejector and put the Triumph breach plug in it the ejector always seem like a awkward system to me I much prefer the Triumph plug and since no one else seems to have tried it as far as I know I though a report was in order.
First: I measured every thing carefully to make sure I did not get any surprises.
Second: put it in and checked fit, still looked good
Third: took it out and shot it.
Results: no blow back [will try and include some pictures]am quite happy with the results. While the target is not quite the best it is with in my average with this gun.

Three shots into less than an inch at 100 yards??? :woot:

My Best. No leg steak.
 

This is my best , aveage is about like the one I posted, it is hard to get a no wind condition around here and some days since I past my 70 birthday are not what they could be.

Looks GREAT to me!

I would complain about that AT ALL. What load are you shooting outta that there tack driver?

Now that is some awesome shooting. wow

The first target was from my Endeavor [this years gun] and I was shooting 140 gr of BH with a Lehigh bullet a 50/40 200gr with a blue MMP sabot.
The second target was by my Triumph it was loaded with a Shock Wave 250 gr and a Short Black Harvester sabot and 120 gr. of BH both were shot with Winchester primers off the bench rest at Cleburne County range where I often shoot.
While I love the Endeavor I have not yet been able to get it to shoot as good as the Triumph. But I had to lapp the barrel of the Triumph to get it to shoot that good. Finding the load is the biggest problem to getting them to shoot good no two ever like the same load.

A .210 group??? Shucks, I thought you could shoot. :party0005:

Well you know how it is when you get old things start slipping starting with the belt line.

I can't think of but one person who could probably shoot better than that, and with a CVA some APP :s2: and powerbelts no less.
I hope you can make it in April:s2:

Look up the IL records for PRB bench rest for 1978.

Excellent shooting.

140 gr BH209? I thought they warned not to exceed 120 gr? Ever. Obviously you're seasoned, so I'm not questioning you. How did you get to the point where you felt safe going 20 gr over the max?

By doing my own pressure testing. Blackhorn runs about 15 % less pressure than 777 for the same load and velocity they are very close in velocity up to 110 gr., after that which I believe to be the point at which 777 starts coming out unburned Blackhorn shows some improvement in velocity over 777.
I do not say that anyone else should do so if they do not have the test equipment they could run into something I have not, also I do not go over 250 gr with this load as the pressure peak rises sharply with a 300 gr bullet.

redneck pressure testing at its best! :D

And with a rifle half the cost of a TC!

And factory form with no swap out parts! :happy0157:

Thats at a dollar a shot Gander, just to make it interesting.
