Hi Gents, I just got an ARMS 17 QD mount, and it won't close on a standard Weaver rail. Can only push the lever about 60 degrees from open towards closed position, and then it stops, and actually locks in fact too, but lever can't be pushed it any further to flush position, it sticks out...

Thanks !

Well, is it now 13 mm x 0.75, as stated some posts ago, or 13 mm x 1.25?

Hi Guys, on Remington home page in every bullets data chart there is a column I couldn't figure out: Average Wt/Ca. What is this abbreviation? Thanks

Well, interesting thing happened. I had a measuring gauge made based on the SAAMI dimensions of a .30-06, which says case size is OK, if the distance from the bottom of the cartridge to the reference diameter of 0.375" on the shoulder is between 2.0487" and 2.0587". Before having this gauge...

I knew all that too, but thanks...:) I just want to make my own comparator for .30-06. For that I need a diameter to be in the ballpark. Just a number... :D

Hi Bob, thanks for the picture, but this in fact does not answer my question. My question was what is the inside diameter of this insert (the diameter that touches the bullet while measuring). I know this insert is for .30 cal, I know .30 cal has a diameter of .308., and this insert has an ID...

Thanks for all the replies! Can anyone tell me the diameter of a Hornady (or other) bullet comparator for caliber .30 please? I want to measure the head-to-ogive distance... Thanks

Hi There, I use munition reloaded by my friend to my .30-06 Tikka, and more times than not, it is a bit difficult to close the bolt on some of the cartridges, but there is no scratchmark on the bullet, so it’s probably not bullet seating depth. What does he need to check next time when...

Read my original question, then compare your answers with westcliffe01's. By making minimal efforts, he understood it and answered it helpfully. You still don't. Have a nice day

Dear westcliife01, THANK YOU, this is exactly the kind of answer I was looking for from Someone who tries to understand the question instead of answering some nonsense, like "the drawing is not perfect, so what?" (let alone from someone who's been engineer, claiming to have "been there done...

If this is the case, I honestly don't understand your first answer. Wouldn't take too much for you to start drawing datum C (0.748 x 0.108), put the 45° lines onto the corners of datum C. Then just measure if the width of the 2x45° edges can ever be 0.835. No, it will be 0.856. If you find, how...

I don't do CAD drawings for fun, of course I want to make it on machine. But if you can’t do it on paper first, based on the drwaing’s dimensions, you can’t do it on machine eighter. That's why drawing are for. Your question shows you didn’t even try to understand the geometry problem, and ask...

Thanks, but my question was not about wiggle room, it was pure geometry of the MIL-STD as shown in every image on th net, but I probably couldn't explain it precise enough. The way it's drawn it can't be machined, cause some of the dimensions seem to be "over-defined", meaning there are 3...

Hi Guys, The other day I tried to draw Picatinny with AutoCad, and I am a bit confused about cross secction dimensions. At first look, at least one of them can’t be right, even if it sounds ridiculous. Every drawing says rail width should be 0.835” (let’s forget tolerances for...
