I too have a Meister and use the stop ring bullet. You ain't putting enough powder in. I use 14.2 of H4227. I mostly use it at 100 yds and accuracy is superb.

Get the correct books' read them ' and the Q are answered.The Germans had and used  optical devices ' the same thing that we call a dioapter.The third vol. of Rowes book has several shown.

Hello Vsig
      If you ever get tired of your Buechel I would like to try and buy it. Enough of that, I just got back from the range and had a bad time with vertical much as you described. I was shooting my Aydt with 14gr 4759 cci200 pri and a 168gr bullet cast 20-1. This load has shot for me in the past,but not today. Out with the chronograph and found that my sot to shot velocity was varring more than I remember in the past. Anytime the velocity would fall off by 50fps the bullet would print 1.5 inches low, these bullets all weighed to the tenth of a grain and I set the hardness with a tester before I ever start casting.
      So i guess my question is what causes the most change in velocity, bullet hardness,lack of any type over pwdr wad, lube or is that how 4759 burns?          Thanks Nick

Nick, sorry I got you and vsig mixed up in my response. It was intended for him. FITZ.

To Nick Marino.  The Buchel is'nt mine  Yet'' I just had it to ring out to see if it would shoot. This discussion about Stop ring moulds'if every thing is correct' when the bullet is seated in the case ' loaded into the chamber  and the lever closed  the nose of the bullet should justKiss the throat.Isent David Mos a chamber cast of my Aydt and this is just how my bullet works.This bullet wt.is 162.5 gr.

to  N ick M.Inever shoot my Aydt at 100 yd. as all the matches are at 200.I use it for offhand only  but when I first got it Ishot it some from the bhench just to see what it would do.I think with a good wind reader  doing the shooting 'it would keep most everything in the 25 ring.It is the most plesant rifle to shoot offhand that i've ever shot.W hen you fire a shot and call it 'thats where 'it will be.Are you sure about the Gain twist?Ihave read all of Tom Rowes books and he never mentioned any of the brls. being gain.Maybe you should get in contact with him.AMgoing to Tulsa this wk.Hope we get some good shooting weather .Verl.
