Bullet and Headspace Comparator Kit, 14 Inserts, 6 Bushings

I recently received the comparator set from Altitude Craft, and it’s a well-built, highly detailed tool for precision reloading. It’s as fully complete as any other set out there. I’m currently using it on both .223, 28nos, .30-06 and .300 Win Mag for checking chamber length and bullet seating depth. The storage box is compact and protective (something that other more expensive brands don’t include), the labeling is sharp and easy to read, and the color coding looks great while making organization simple. Functionally, everything worked perfectly. The set I received was slightly different than the product photos, but not in a way that affected use or quality. When I reached out to customer service, not to complain, but to see if I could get different set screw, they went above and beyond to help me out. Their responsiveness and willingness to assist really stood out. All in all, I’m extremely happy with this set. It’s clear that Altitude Craft cares about both their products and their customers.

I have only played around with these to figure out how to use them. It looks like these will work great to check my shoulder bump and Ogive for reloading great quality. Looks like they will last a life time. Comes in a case so you don’t loose parts

Good item, wish I had bought this years ago.

They really should offer a solid head in this with no hole in the middle

The kit is well made, has a nice storage box and does everything the name brand kit does at a greater value. Very satisfied

This kit is a tremendous value. I use this primarily for verifying reloads and factory seating dimensions on 5.56, where OAL measurements can be all over the place with open tip match bullets. Toss the adapter on your caliper, insert the bushing, zero it out, and you're ready to go for super simple ogive or base to shoulder measurements. A fantastic tool at a fraction of the price of the big brands. The metal tin/carry case with foam cutouts is a nice touch for bench storage, though it didn't do a great job of holding things in place during shipping.

ease of use size

Packaging is comfortable. Nice quality. I would recommed compare known messurements and notice the difference before usin. I had hornady comparator and did an equivalence between both.

Works well, and is consistent

good price , makes it easy to check bullet length for different bullet heads and easy to check shoulder length too. Great tool for reloading.

Very accurate. Nice packaging to keep everything organized. Excellent value and quality for the price. No need to pay twice as much or more for the same thing from the big ammo makers. Definitely recommend.

They work as they should although the 330 is a bit big for .222rem cases or so it seems.

Very good set of headspace and seating depth gauges including 17 Hornet.
