Not being one who accepts change readily, I decided to wait until the New Model Ruger transfer bar system got passed it's 'prototype' years, and assure myself that Ruger got the 'kinks' out. So, now, about 43yrs. =/- later, I purchased my first New Model from our own Forum member Gunsbam69 (the transaction was superb and I recommend him heartily). I bought a Williams Shooters Supply 'distributor exclusive' SS Bisley in .45Colt (single cylinder). I was going to immediately send out the cylinder to David Clements to have the chambers checked and reamed if necessary; and I was going to immediately change out the trigger spring and gently stone the action etc etc. Then, I took the advice of so many more-knowledgeable shooters: "shoot it first before you start changing and 'fixing' things". Well, two things became apparent immediately: 1) the gun shot way more accurately than I could possibly shoot with one bad eye and very old muscles; from sandbags at 25yds, I was getting a large ragged-hole group (maybe 2.5inches end to end); and 2) this gun just will not lead-up the barrel or the chambers no matter what I feed it. I've put undersized .451 lead SWC's thru it; also (Missouri Bullet) .452's of 12 and 18 hardness in both SWC-type and RN; even some 230 RN with the 'sprayed-on' lube of unknown mfg. My loads are relatively light: around 6.5grs Trail Boss or 7.0grs Unique. So far I've probably put 200+ rounds thru it, and after each session (usually 50 rnds), I come home and clean it. After the first patch, I check for leading in the bore and each chamber... nothing in the bore, and very minimal in the chambers. I tried to check for barrel constriction at the threads by using the tight-patch method but feel absolutely no restrictions. I tried dropping a jacketed (old mfg?) Sierra .4515" bullet thru each chamber and it would not go thru any of the 6 throats.....(unless I 'hammered' it thru). So, at this point: "if it ain't broke", I'm not fixing it (other than maybe a Wolff trigger spring.......MAYBE). The Gods have smiled upon me, and as long as I have one good eye (even though it's the wrong one) I'll keep shooting this NEW MODEL; but I probably won't buy another one . I still have one Old Model in each caliber and will remain stubbornly faithful to the traditional SA actions, so please don't tell anyone about my satisfaction with this "new-fangled" design............
