While I cannot add much about the screw in question, I can say with authority that the long slide 48 on a vintage 03 sporter will reach 1153 yd with a fairly standard load using a 220 gr cast bullet. It was quite fun, and not very difficult to hit the Whittington white buffalo, once we spotted a ranging shot. It did take about 20+ rounds to accomplish that, however, as I had no ballistic data to attempt it with before hand.

Jerry, A trick I have used on potential flying springs is to tie a thread or string to them. Can't do it on every application but when its possible I do. Even if the thread doesn't stop the flight totally they don't go far with the drag. Now ball bearings...magnetic sheet is as good an idea as I know of. Thanks for the suggestion.

Another post for Fred:
It is a good idea not to just get a die for that thread size, but also a few taps. Victor doesn't have them, but they are on ebay. When I make screws, I often find myself tapping a section of aluminum rod to act as holders for the screws I've made. There are lots of ways to slot a screw, but perhaps the cheapest and fastest way to do it, is to use the cutoff wheel of a Dremel tool. You may have to build a jig to keep the angle right. And for what it is worth, I can't work on stuff without a set of optivisors.

The Dremel for slotting works but the screws are so bloody small even the narrowest Dremel wheel is almost too large. If I have to make a screw this small having the taps like you suggest is the only practical way to do it. For tapping aluminum I have been known to cut threads on a steel rod, and use it to make a crude tap. Works for aluminum. Sure wouldn't want to try it tap steel.
Brent now you're shooting an '03? You're starting to get all 20th Century on us. I soon expect to see you shooting a Black rifle.

An adjustable jewelers saw frame using a short section of blade is good for cutting very narrow screw slots. I also have a 6" hacksaw that cuts a very narrow kerf, but the jewelers saw is even narrower. I never looked, but imagine that very small and narrow slotting saws are available that could be used in a Unimat.

Received the proper screw from Mr. Ferguson today. It is now on the sight bar with a drop of blue loctite and the sight staff is back on the rifle and all is well with this part of the world. A tiny part to be sure but it is right. Fortunately I did the reassembly in my magnetic dish which caught a dropped, nearly microscopic screw and kept me from having to beg for another. Pheww.
Bill thank you so very much for supplying the screw. It is people like you and so many others on this site that give me hope for humanity.

I am doing a bit of sight work too, and ordered a slitting saw arbor, I will post a picture of the slitting saw's use in cutting a slot for a screw when it gets here.
My computer problems are temporarily over, thanks Art for posting things for me.

Thanks for the information. I have s slitting saw for my mini lathe but it is about as thick as the screw head on the screw in question.

Actually, what is needed is a slotting saw, not a slitting saw. You can slot with a slitting saw, but can't slit with a slotting saw. Jeweler's slotting saws commonly start at 0.008" and go up from there. Victor tools again is your friend, offering jeweler's slotting saws in several diameters. http://www.victornet.com/subdepartments/Jewelers-Saws-1-1/2-to-1-3/4-Diam./1591.html
