Re: Depth adjustment tool
Well today I am having problems posting pictures again.
Today I noticed that on the right of the page while typing, (img) and(url) is turned on.
On another forum I post pictures on, I need to cut them off to post a picture on that forum. Do they need included, to have the picture apron this sight.
Help needed.

Re: Depth adjustment tool
Not a bad looking home made tool. Hate the Zoink thing but easy enough to open page back way.

Re: Depth adjustment tool
Thanks marlinman
That saved me some thinking. I will try with the ends on another picture later.
So with this tool there are several things that could be accomplished. It does require to destroy one case, but it gives the opportunity to see how things fit in the chamber.
How far the bullet can fit in the barrel. If you want space before bullet contacts the lands. Or do you want the bullet to engage the lands.
That will give thoughts on powder charge capacity.
And your wad selection possibilities.

Re: Depth adjustment tool
I find no need for something like that just drop the bullet you are going to use in the chamber and use your caliper to see how far it is to the end of the chamber from to base and that will tell you how much it will be in the shell casing then you know what height your powder and wood needs to be in the case have fun and keep shooting

Re: Depth adjustment tool
This widget is simpler, drop in case, put bullet in and adjust it until the bullet chambers with amount of effort you want. Then run your compression plunger down till it touches, there's your wad height. 1 for .40 and 1 for .45. Simple to make.

Re: Depth adjustment tool
Those widgets look interesting, but wouldn't you need one for each bullet nose design?

Patch to bore diameter bullets and the correct paper thickness. Let the results on target tell you the seating depth and never worry about leading again. Seems simple to me. Bobw

Re: Depth adjustment tool
I think the tool gets seated down inside the case - whatever wad you're using gets stacked on top of that screw thingy and then the bullet of top of that - screw in or out to simulate different seating depths of whatever bullet you choose. After you get the right depth your compression depth is whatever the measurement turns out to be when measuring from the case mouth to top of wad or from base of case to top of wad. I don’t think the tool was designed to simulate the nose of a bullet - same tool can be used to determine compression depth (seating depth) for any bullet you choose. At least that’s my understanding by looking at the pics. Looks like a handy little tool.

Re: Depth adjustment tool
Patchbox, you are mostly right on how it works. No the wad is not inserted, the threaded adjustable screw top represents the top of the wad or wads, put the asm. in the case and insert the bullet, a DD PP in my case. Just screw it up or down to find the sweet chambering length so desired. The the wad height is then established. No destroyed expensive brass.

Re: Depth adjustment tool
Thanks for the clarification. I was thinking a sacrificing a case and boring the primer pocket to a 1/4”-28 tap drill size and threading 1/4”-28 and using a socket head cap screw for depth adjustment but your idea is way better - no need to ruin an otherwise good piece of brass.

Re: Depth adjustment tool
Plus you can close the breech on the case to see how far you’ve gone into the lands. With a screw sticking out the base of the cartridge closing the breech is a no go.
