Need Help With an Experiment.

[murphy]

Is there an accuracy conscious person out there who would like to help me with an experiment with reguard to accuracy windows. What I need is some one with a factory produced sporter weight rifle,around 8 pounds weight with a good bedding job. Please leave behind any previous ideas about seating depth or accuracy development and proceed as follows. Using a chronograph find a good strong load with a low shot to shot veiocity spread. Next using a dummy round find the exact over all length of a loaded round that just kisses the rifeling in Your gun. Measure the distance between the rifeling mark on the bullet and the neck of the cartridge case and split that distance into four separate and equal increments. Next load up some rounds in batches of 3 with the 4 different over all lengths. Try to eliminate variables like wind, mirage,copper fouled barrels and so forth and bench rest the four batches. I would like to make an educated guess and say that your groups will shoot to different points of impact in the vertical plane and that your highest and lowest groups will be the tightest,because thats where the accuracy windows are located.Please let know what happens? Murphy.

No Takers.

Come on Guys,I think that I am on to the best accuracy enhancement idea since the floating barrel and certainly the quickest way to find a pet load, but cant get anyone to fire 12 shots to try it out. Have had good results with 5 rifles but need a second person to try it out so that people can benefit from My discovery. Its a sorry state of affairs when I have to answer my own post,I think that Ill go and eat worms! Murphy.

Thanks for your reply,will certainly follow up on the information you have given Me. Have recently developed a number of loads for a brand new inexpensive factory rifle using this method and the results were astonishing. Trouble is its hard to tell if I have a brilliant method or an outstanding rifle and I cant afford to keep buying rifles to find out, so thats where the second party comes in. I dont want to be famous,just want to get a great a great idea accepted so that I can help people. Trouble is I have come up against a wall of predjudice. Reguards Murphy.
