concentricity gauge?

Geemonites!!! Is it needed? It's a hunting rifle. A factory made hunting rifle at that! Oh, and it's 338 Winnn Mag. So I'm not shooting at an animal 1000 yrds or further out! Maybe 600-800 yards later on down the road, but certainly not now!

If I buy good dies and good ammo components wouldn't that give me "acceptable" runout?

So then I shouldn't worry about buying a stupid gauge right?

Or would it make my groups tighter at closer ranges? Hence the justification of needing one.

concentricity gauge?

I've been reloading since the late '60s for at least a dozen rifle calibers and have never seen the need for one.  My dies are standard RCBS, Pacific, and Hornady.  I can get moa or better loads for all of my bolt action rifles.

Save your money.

You are making thing things

You are making thing things way more complected than they need to be. When you are reloading just make sure that you are consistent. Do the same thing each and every time and you will have ammo that is just fine for hunting and more accurate than you just may be able to shoot.

I know a couple of bench rest shooters that load with a Lee Classic Loader. About the only other tool that they have is a neck turning tool. These loaders have loaded millions of hunting rounds not to mention target rounds. When I started to reload you could buy one for $9.95.

Your gonna run into a lot of

Your gonna run into a lot of people that believe things like that are needed. They claim to get better accuracy, I'm not convinced they do. All kind of needs are out there waiting for buyer's and they find the buyers! I seriously doubt a lot of that stuff is really needed for long range shooting, maybe match shooting. But a tecnique or tool that gains you .015" at one hundred yards isn't worth it. Furthermore I doubt people that claim these grest increase's actually get them. Let me know when someone can go out and shoot a 3/4" group every day from anything other than a target rifle.

A tool I've been hearing about for years is the over all case length that measure's to the ogive of the bullet and you can set your bullet's .006" off the lands for better blah blah blah.

All my tools are very old, they still work well! I strive for 1" group's at 100yds from a bench; can't do that well from a field position. You get caught up in the tools and gadget's, reloading get's real expensive. And all you wanted in the begining was to save a few buck's on ammo!

thank you

Thanks all.  Like I've said all along.  I don't know anyone around who reloads or has any practical knowledge of hunting.  So thanks for the advice!  

By the way.  I'll be receiving my dies tomorrow.  I decided on Redding.  A Type S Full Length Bushing die, the Large Decapping die, and the Competition Seating die.  

You're right Critter.  Putting it all together piece by piece gets pricey.

I use a straightening tool

I use a straightening tool designed for aluminum arrows for this purpose. It can measure the slightest bend in an arrow and allow you to return it to perfect concentricity. ( I guess that's a real word)

Not necessary by any means but fun to check loads with.

I have one of those gauges.

I learned that consistency in the reloading process, sorting cases by weight, selecting and seating bullets of the same length, and paying attention to seating the bullet will give me acceptable loads without the use of the gauge tool.

I sort my cases by weight and bullets by length. There will be variations and that's what I'm striving to eliminate. I also hand weigh each charge. That and seating the bullet, turning the case 1/3 of a turn and seating again, turning the case 1/3 of a turn, again, and seating the bullet gives me very consistent and accurate loads.
