Pellet Head Size gage

I like the idea of dia. check with out any sizing going on v/s the Beeman pellet sizer from years ago. Problem with sizers is you have to start over size to arrive at your target. We really do not have that option. So far my rigs tend to prefer the 4.52mm in .177 cal. ( at least that is what the tins are listed as). 4.50 and 4.51 have moments of glory but are not consistent for me. I have 4 tins of 4.54 but as of yet no time to test. ( these are all round nose). I have not converted my USFT to .22 yet so my experience is limited to .177. My comments are based on my Walther LG300 Dominator, Anz 2025 and Anz 2002. I have not had the usft long enough to discern its likes. ( 2nd hand unit )

That measuring device looks very good. Much of it's accuracy will come down to the precision of the machining and the quality of the dial indicator. Both of those things do not come cheap. I use a bullet comparator with a flat granite base and a Mitutoyo dial indicator. A machinist's reference cube acts as a base to place the head of the pellet with the skirt hanging over the edge. You must use a flat tip to measure round objects.

I wish I could say that it makes a difference. Not with my barrel or pellets. Maybe if the target was moved out to 50 yards.
 
sorry to tell you this but those where deemed a scam years ago. does not help at all.. good luck on your quest..H.B.
 
I beg to differ Herr Deliterman, Those of years back were units that swagged to a specific size as I stated before. The unit presented above is strictly a gauge. Allowing one to sort head sizes with in a tin into groups of a known range dia. wise. Depending on your launching device and skill sorting by head dia. as well as culling deformed pellets can make a difference in our bench rest game. The improvement in pellets from the 60's-80's has been dramatic. Other than culling deformed pellets from bulk packed tins, at ten meters thats all you need in any of the top match pellets in.177. In the other styles of pellets there has been somewhat less effort applied by the mfgs. the trickle down effect of technology has again made noticeable improvements. The equivalent in rimfire is test firing different lots of ammo to find the Holy Grail for your unit of choice.
 
I contacted Ray about the gauge. These are not inexpensive. The unit with dial indicator reading to .00005 is $360, to .0001 is less. Ray will make one up as needed. Not a production Item.
