Higher learning started with this tool.

If you have a caliber you shoot, and multiple rifles you shoot it in, this tool is great because it gives you an ANSI reference of zero. I have never used the bullet seating depth tool function. It is a great tool for new reloader's who want to learn to set the shoulders back a certain amount when setting up your sizing die. This lengthens brass life and ensures proper chambering.

Easy to use, a MUST for the precision sh

I dabble in Long Range target shooting. I love to know what my bullet is going to do when I pull the trigger! This gauge insures the casing fits correctly in the bbl.

Excellent tool

The neck gauge for proper head space is easy to use and is the finest I have found. Now the complaint, I wish they carried it in 25-06.

Took some fiddling

The freebore tool would not work on my Savage Model 12 until I polished the extractor ramp and the back bevel on the rim of the tool itself to get rid of the oxide coating and sharp edges. Once the extractor would engage without collapsing the tool first it was spot on. So you could argue that it helped me to improve my rifle :). The micrometers are great, and I find them much easier to use than calipers and gage bushings.

Headspace mic

I only want this for headspace. If I could buy this tool for that function alone I would. I do OAL measurements with my Hornady OAL Gauge/Comparator but this RCBS mic does the headspace measurement and I'm giving it 5 stars just for that function.

great product

I've reloaded handgun ammo for many years, but, just started rifle rounds a few years ago. I'm trying to be a precise as possible and follow all the good practices. I have one 204, and all my reloaded cases are ones that I have fired in that one rifle, so, that makes things much simpler. But, I have many .223's and bumping brass to fit a variety of my guns was a challenge. I have tried to measure headspace with several products but it was even hard for me to understand what I was actually trying to measure. I have several other measurement tools like go/no-go guages, and they have their place, but nothing actually gives you the measurements you need and especially this easy. You can measure, accurately and easily, factory ammo, and then once fired brass from each rifle, and then easily set your dies for a case for a specific rifle, or, cases that will fit any of your rifles. I've not used the bullet seating depth gauge but the headspace part is wonderful.
