Hex nut bullet comperator

[mousegunner]

Anybody use one? Looking for something other than my RCBS case micrometer.

 

[moondog]

I have , haven't used it in years

 

[Doug Beach]

Works fine.

 

[R.Morehouse]

For bullets , I suggest the Holland Gold Standard unit. It is quick and easy to get consistent results. Watch the video.......I have one and like it .

Had one but realized it was not capturing the bullet ogive anywhere close to the regular sinclair inserts used with the caliper clamp on comparator.

For my BR stuff not so much, but for plinking or just stuff to shoot always.

I got one years ago. Sinclair maybe? It's still in a drawer somewhere I think. There are obviously calibers not covered with the tool having only 6 sides. I have fairly large hands but the size still makes it clunky & a pain to use juggling 3 items. I use Davidson seating depth checkers which attach to your calipers with a small set screw. They were made long before that Hornady thing or its predecessor at about $8 each per caliber (.17 thru .458 no .20) & infinitely handier. Unsure if anybody continues making these since Alvin closed his shop but I sure prefer them over the others.

I found a place that makes some like the Davidson but looking at $70.00 plus SH if I remember right. Mostly shooting 200-300 walk and paste matches so don't need anything too fancy. I'm not really into the Hornady ones, I'm sure they work but don't rub me the right way.

I have had two Sinclair's (6mm and 6.5mm are on different ones) for years and used them exclusively. When you think about how you use a comparator, it really has little to do with the "absolute" measurement compared to a standard and everything to do with the "relative" measurement compared to the rifle. In other words, if your rifle shoots best at 3.34" in the comparitor, then who cares what 3.34" really represents - it's relative to your barrel.

I recently purchased a Hornaday comparitor set, mostly because they appeared to be easier to use and they are. But they also aren't even close to the measurements from the "hex" comparators. Which is right? I don't really care, because it is all relative. I had to go back through and re measure my OAL to the lands, but the ease of use of the Hornaday system is worth it.

Exactly this. ^^^^

Right. Everybody gets their own numbers from whatever device they are using. The Hornady and Sinclair inserts will give totally different measurements for my BTO with all calibers.

Prefer the Sinclair nut over Sinclair comparator insert. Easier to ensure the caliper jaws are square with the large surface area of the nut.

 

[mikecr]

Yeah, I like the nut.
It's simple and as meaningful as any other toy out there.

 

[TominSWNY]

No two nuts measure the same!

 

[geo.ulrich]

I'm wondering how you know this ..........

 

[TominSWNY]

By having two!!

 

[snert]

By having two!!

This only tells you THOSE two are not the same. But again, lets not get too technical about nut sizing.

I lost mine about 10 years ago. Replaced it with the Hornady tool. About 3 months ago it popped up in a desk drawer on the opposite side of the house from all my reloading stuff. Now, if I could just find that pot of gold I hid from everyone including me.

 

[skeeljc]

Works well and easy to use. I prefer it over the Hornady/Sinclair tools.

I made this one 30 some years ago from a stainless nut. A simple reloading tool that works nicely.
