Would it be made simpler if I just recorded all adjustment in M.O.A. When adjusting the scope to that setting, I would simply turn the elevation knob until 3 lines are revealed on the micrometer post and then rotate the knob a little further until the number 8 lines up. What I have been recording in my note book is the graduation marks on the linear micrometer scale.

However, instead of 25 clicks for a full rotation of the knob, there are 50 clicks per revolution, and each click is a 1/4 M.O.A. scope and as you pointed out earlier, the click adjusting knobs for elevation and windage are marked with 25 graduations for the 360 degrees. As you, and most of us who are competing know, the act of keeping detailed notes regarding our experiences is without question indispensable. I would like to revisit your response and your very informative web site for the cast bullet group on yahoo. joe33050 -it's been some time since you posted some very usefull information in response to a member who, at the time, was dealing with non-standard scope mounting block spacings on his barrel. (The centers are 7.2" because 7.2" = 1/5 of a yard.) Steve can make blocks with the indents 7.2" apart even with hole pair centers other than 7.2" apart. The book is in "FILES", the Table Of Contents is in "The Beginning" The above from "7.2 SIGHTS" in "Cast Bullets For Beginner And Expert", Second Edition, which can be found and read online at: (You need to Login or Register to view media files and links) Unertl for sale UNERTL 6X TARGET/SMALL GAME SCOPE, EXCELLENT CONDITION : 13248,29 R Vintage Classic J. 250" or a quarter inch or about a quarter minute of angle shift in bullet impact per click. Divide 3600 inches in 100 yards by 7.2 inches center distance between scope blocks and you get 500. Each click moves the telescope one-half of one thousandth of an inch. The adjusting knobs are marked in 25 divisions, and there is a click between each division, so there are 50 clicks per revolution of the knob. These sights attach to "scope blocks" on the rifle barrel, which are most often 7.2 inches on center. It is entirely practical to move these sights from rifle to rifle, re-setting the sights each time. They have adjustments on the rear for focusing the crosshairs, and on the front (Fecker in the center) for eliminating parallax. These have adjustments built into the mounts that are (mostly) click adjustable and clearly readable so that settings may be recorded. Outside adjustable telescopic sights include Lyman Targetspot and Super Targetspot, Unertl, Litschert, Fecker and Davis brands. Telescopic sights may be categorized as "Outside Adjustable" and "Internally Adjustable." the spacing of the 2 bases is 6.5 " center to center? I don't want to drill any more holes in the barrel of course, I would assume the spacing between the bases has something to do with the calibration on the mount adjustment. Can some give me a good list of the pro's and con's of each type mount and tube length? I can't seem to find any good comparisions between mounts and the recommended tube lengths for each type.OK.
I would like to purchase a scope and mounts before our next match in May. The scope will be mounted on either my Browning BPCR or my Rolling Block, both have 30" barrels. With some luck we may have BP Target matches going again next year. What I want is to shoot Silhouette and the occasional long range match. Local scope shooters who use MVA scopes and mounts, tell me not to get the 23" tube but to get the full length tube and as a couple of them are Master Class shooters their opinion has more than just a little bit of weight to it. Also there is the question of what size riser blocks to get. As I understand it, the DZA Unertl style mounts will give more elevation than the MVA Silhouette mounts although their Creedmoor Mount is equal in total elevation capability? When I talked to MVA they recommended their 23" scope for silhouette while DZ Arms recommendeds an 18" scope. I have also talked to MVA and DZ Arms about their scope mounts, and quite frankly I am more confused than when I started.
I have talked to other scope shooters on tube length and which mounts work best. Spent over $500 on new lens for my glasses over the winter and my scores have not gotten any better. I have decided to buy a scope for my BPCR, my corrected vision just isn't up to the task of seeing the Turkeys or Rams anymore. I realize this has been hashed over before in the forum, but after reading the previous threads I find myself still confused.
