How many of you true up your bullets?

You would be surprised how much even match grade ammo you load will be off and not true.

I've dabbled a bit. Although, from what I've been reading lately, a better approach is to get a quality concentricity gauge to determine your runout and then work to address what is causing the runout. I've had decent results using the Hornady concentricity gauge to check runout on rounds i've loaded using a Redding competition seater die, but from what I've read the Hornady gauge may be painting a prettier picture than what's really happening. Planning on getting a Sinclair concentricity gauge to compare. This hobby (addiction) never ends, does it? LOL.

LOL I can't shoot that accurately with having old eyes and such to begin with. I am as happy as can be with plain old Core Lokt bullets to begin with. Match grade bullets let alone the setup to true up bullets would be lost in the noise at my house. It is however interesting to see the lengths some go to in search of accurate ammo. I am impressed.

I only have two rifles that I "MIGHT" be able to tell the differences if I went to those measures with my loads. Even with them though, as long as they are putting the bullets into groups at, or under an inch at 200yds off the bench, I am happy. They still drop deer, yotes, and hogs just fine even if they open up just a tad.

If you're including bullet weight...I still do for my 22-250. And I use to for my .38 and .45 Competition bullets...but not anymore since I've retired from competition.

I decided to take my addiction to the next level. I just ordered a Sinclair concentricity gauge. Also, I read in the comments on that site for that product that a guy would use the octagon bullet comparator (sp?) to check the bullets by simply turning the gauge to the side. Since I already have one of those comparators, I'm going to give it try.

Hopefully, the sum of the little things will make a noticable difference.

Factory ammo, even match grade, can be "off" in many ways.

You can measure concentricity, but how do you know that the bullet weight and powder charge of every round in a box of 20 is consistent?

I true up all my 308 and 270 rifle bullets with a Hornady concentricity guage. I don't really know how much it makes a difference other than making me feel like one less varible that I have to worry about.

I also do it because I shoot a 500 yards with both guns.

If the bullet run out is more than +/- 0.0005", the problem is elsewhere in your loading process. Even better when the needle does not move! I can possibly lie in your chamber(crooked chamber, yes it happens), dies(bushing dies are notorious for runout), too much neck tension, etc.

I had a Redding bushing die respond well to inserting the bushing with the stamped lettering facing down in the die. I had another die that liked the bushing locked tight. Too much neck tension is another common cause for run out. In my precision loads, I do not use a expander. The neck tension is controlled by a bushing. I've been having good luck with Harrells dies in my 6mm calibers. (he only makes them in 6PPC, 6BR, 30 BR and 6mm Dasher)

First time I've heard this, when actually old style dies with expander buttons are a common cause of runout.
But on subject of measuring runout, I'm always curious as to what place on the bullet or case measurements are taken. Anyone care to comment? Please do.

I've read to check runout on the case neck near its junction with the shoulder as well as half way up the neck. Then once loaded, check the bullet close to the case neck. Was just reading article earlier today on 6mmbr site on the topic.

I usually check the case neck before and after sizing. If its absolutely perfect, throw your charge and seat a bullet. I run the gauge on the ojive, approximately where the bullet engages the rifling lands. If I have run out, its usually found in the seating process. Maybe too much neck tension, carbon buildup inside the case neck, dirt, etc. Just a process of elimination. I use Wilson hand dies and an arbor press...I can actually have a feel for bullet tension and have an idea what round to check.

I reload a lot of match grade 223 with redding competition dies. Some brass still sneaks through, and you wouldn't even see it until you shoot it.
