Screw thread chart
Reply #1 - Nov 27th, 2017 at 8:09am

Sometime back somebody posted an old chart about screw threads that showed the fraction size, not the screw number size. Example 3/16-32 not 10-32.

I tried a search but have not had any luck. Any luck would be most helpful.

thanks ron

An easy reference to remember for number size screw threads is
The 0 or ought size is .060 in dia.
For each number multiply .013 time the number and add to .060.
Example
1= .073
2= .086
4= .112
And so on.

The .32 Miller short uses the shorter 1.290" long .357 Magnum case (35,000 psi) trimmed to 1.270" and the .32 RKS uses the longer 1.605" .357 Maximum case (44.962 psi) cut back to 1.470".

The longer .32 RKS with more case capacity is less sensitive to manipulating powder changes and the thicker walled cases of the Maximum case have a longer life span and are able to take a heavier powder load. 

These cases are tapered and necked down with a .223 FL sizing die.

Dean Miller initially developed the .32 Miller and Ron Smith a short time later developed the .32 RKS which is also the same case used for the .25 RKS.

just to add to the conversation   the 357 maximum case has been hard to find so the alternative  that works out quite well is the 360 DW case.  starline has been producing this and I have found it easier to obtain  the case is about .020 shorter than 1.470 and no trimming required just size in a .223 die  you can also chamber with a 223 reamer and use a separate throat reamer

I'm looking at new scopes and lots of them refer to mills instead of inches can someone tell me the difference between a mill and an 1/8" or 1/4"  at a hundred yards?

Thanks

Redfield International Match Rear sight
Reply #13 - Mar 3rd, 2022 at 5:44am
Print Post  
Can any of you fine folk tell me the click adjustment size for a Redfield International Match rear sight? Is it 1/4" or 1/8"?

I have looked in Stroebels Old Gunsights book and it mentions the International or the International Mk 8 as being the markings on the actual sight. Mine definitely says International Match.

The same page shows an advert for the Redfield International Match Metallic target sight with 1/4" clicks. So very much thinking that this is correct for my sight regardless of the markings.

Cheers

1/4 inch most common but you can calculate exactly using a dial indicator. Set the rifle up solid and level . Measure actual movement number of  clicks. I use 12 mostly. Then use a chart like Lyman or Williams  publishes that factors sight radius to confirm movement in MOA

(You need to Login or Register to view media files and links)

Another advantage to checking with indicator is confirming the sight moves consistently up and down the range. Internationals better than most but old sticky lube often throws the movement off.  Dead stop screws in some sights will hold the staff while the knob still turns too. They all have some backlash. Indicator will tell you of going past and always coming into desired setting same direction is important.
