Great unite bullet O.A.L. measuring
I dose a Great job measuring bullet to sort O.A.L. before reloading when have sorted U know they are same length. Wish bought sooner.
Great Comparator
Very easy to use and the flat tip is the most useful for me. The only way to improve it would be to angle the dial readout to match a humans eye angle from the countertop location. Or, use a LED color display, or both.
May have found my flyer's
Just got done with a ruff sorting of approximately 300 Berger 185gn Juggernauts. about 130 measured .580 to .584 base to ogive ; 60 at .578 to .5795; 3 at .565 and one at .550. now I can adjust my bullet seating and get a better Cartridge Base To Ogive (CBTO)#
Worth its money
Bought this Sorting Stand a few weeks ago hoping it would make my life easier,well it DID !!!!. i sorted 2000 rounds of .308 projectiles in 2 afternoons. After using it for a while just to get the feeling, i found that tapping the projectile into the comparator only with the weight of my index finger it was giving accurate and reliable readings. Sorting my Projectiles gave me evidence that even Match ammo has a difference !!! I would recommend this instrument to everyone who wants that little bit more accuracy out of their handloads.
Tricky to adjust.
Although the indicator is very easy to adjust, I noticed that after measuring a box of bullets, the initial adjustment to zero varied by .0005 inches. Although this might not be much, you would prefer a device that does not have any variance with use.
Lowered my Std Deviation
This is a really nice tool that is well-built. The marble block is heavy and the tool is quick & easy to set up. I measure base to ogive & sort into groups. Bullets aren't perfect, so when you push them gently into this comparator, they will deform slightly, and you may get different readings - depending on how hard you push the bullets into the comparator. Also, (most importantly) the base of most bullets are not flat - they are usually slightly concave (dish shaped) and you will get different readings, depending there the gauge contacts the base. Neither inaccuracies are the fault of this comparator - they are just part of the inconsistencies of bullet making. Most of the bullet length variance seems to be in the nose length & shape of the meplat (tip). I try to adjust seating depth so that a consistent amount of bullet base is going into the case. I ignore the overall loaded cartridge length. I have been getting lots of sub-6fps standard deviations when doing load testing with this method. Now, if I could just get a nice bullet seater that indexes off the ogive, rather than near the tip or half-way down the nose.
Great tool for accuracy
If they read and edit these hopefully this review will get published and my previous one deleted. After living with this thing for a year and using it on and off, I finally figured out how to make it work for me. I have the slug type caliber blocks but the HEX nut comparator actually works better for me. Get some sorting bins, at least 8. Number from 2 to 8 or whatever. Start gaging bullets and pay attention to just the 3rd digit after the decimal and drop into the corresponding bins. You will have bullets sorted to approximately 0.001". The gage has a stated accuracy of plus or minus same. So if you have a #5 bin full of bullets, based on the gage accuracy you should actually be between 0.XX4" and 0.XX6". That's as good as this setup will get you. Cheers!
Nearly a good product
Great idea, great materials, solid indicator, great price...but if you dont execute the construction well, its crap. The post on mine is not mounted square, so the indicator, when mounted, measures a different height depending on where a comparator base or other item is placed.
Almost, but not quite
I am coming from two Stoney comparators on a digital caliper and thought this unit would speed things up. Nice marble block and micrometer, different holders for different calibers. But... The measurement is from the bottom of the boattail to the ogive, not just bearing surface. The flat micrometer insert is not flat and gives different readings at 3/6/9/12 o'clock positions, plus the bullet holders do not really keep the bullet centered. Nice toy, but I am sticking with my two Stoney comparators on my calipers.
not accurate and repeatable
Had this thing for a while and thought it was doing what it was supposed to until yesterday. Was sorting a batch of 250 custom bullets and was getting 10K variance which I thought was odd. Came back the next day to finish sorting and remeasured some that I had sorted and got a different # and then measured some I had not sorted and got the same number with 1K variance. Examined the device and took it off the stand and fiddled with it and the stem doesnt even come back to zero but the digital display did. I have lost all confidence in this device and do not recommend.
