Milt, Randy Ross was shooting a Perazzi with an adjustable rib. It had 3 notches for POI adjustment. He had it altered and it went to 5 notches. I believe he told me that it shot 250 +% high. I don't know who did the work, but could probably find out, if you want to know. Bill Malcolm
Randy's gun shoots about 25 inches high. I temporarily owned the gun. Randy had the barrel rechoked by Tom Wilkinson and had extra notches put on. Randy sure shoots that MX 10 RS well.. He ought to thank me that I did not teach his gun any bad habits during it's short stay at my house.
Randy is looking at shooting a Kolar but as far as I know he is still shooting the MX 10 RS. He did not shoot the Kolar this past yr. I never could get his gun adjusted for me but Randy adjusted it for my 15 yo son and he promptly went out and broke a 96 . I bought a MX 10 RS combo from a friend after Randy bought his gun back (unmodified) and I shot it well. I had contacted Tom Wilkinson because Randy's gun shot so high for me but Tom said the gun's ability to shoot higher was totally due to the extra notches in the rib and the barrel was not modified to shoot higher.
