it does do what i wanted it to do
it does do what i wanted it to do. i do own a different concentric checker but there is no way to adjust any runout on misaligned cartridges. this tool does make it possible to tweak if needed . its not the most convenient tool to use for just checking for runout, yet if there is runout something can be done about it . i am some what unhappy that the spring loaded plunger does have some sloppiness left ,right, up, down in its housing
Hornady concentricity guage
This cncentricity product from Hornady is wonderful and works perfectly. Its the only product I know of that also corrects bullet concentricity with the same gauge. I highly recommend it
Works Great
I have used the centricity gauge on all my loads since I got it. I'm developing loads for 2 calibers of varmint rifles and I'm looking for 1/4 minute accuracy out of them and getting it with some of my loads using various powders and bullets. I feel using the concentric gauge has helped a lot in tightening up my groups. I made an angled stand to put the gauge on as when sitting down the gauge needs to be angled in order to see & read the gauge. That is why I only gave it 4 stars.
Hornady Lock-N-Load Concentricity Gauge
I have been handloading and shooting competitively for about 25 years and I am always looking for something to help get my ammunition as consistent as possible. This tool is absolutely amazing. After just a few minutes to familiarize myself with the operation of the tool, I was able to adjust my ammunition to a runout of +/- 0.001" with very little effort in very little time. I have had an opportunity to shoot the ammunition processed through this tool and saw a 0.25 MOA reduction in group size over ammunition from the same batch that had not been run through. I know that does not sound like much, but it is a HUGE deal when we are talking about ammunition I use to shoot at ranges from 1,000-2,000 yards. There is one small problem that I experienced that prevented me from giving a 5-star rating despite the fact the tool works flawlessly. The snap ring that holds the Bullet Spindle Collar in the frame broke after I had processed less than 100 rounds of ammunition. Customer Service at Hornady was incredible. Not only did a live human being answer the phone, the representative had a new snap ring on its way to me in a a matter of minutes and at my rural address in 2 days. Sadly, it turns out a flaw in the casting and/or machining of the frame is the problem so the new snap ring was not the solution. I had to return the entire tool for replacement. I know that Hornady needs to manufacture their tools so that they function and can be sold for a profit and I am completely comfortable with that. It looks as though making the collar slightly larger and pressing/driving it into the frame would eliminate the need to rely on a flimsy snap ring, Overall, this is an excellent product and I have become a fan of Hormady because of their knowledgeable and professional Customer Support team.
Works great!
Wow,i can not believe how well and easy this tool works.just started playing around with it and i am amazed.It does exactly what they say it will.I am looking forward to shooting these rounds asap.So far i say hats off to hornaday,fair price well built,and can correct on the same tool that finds the runout.
