What do each of you consider the single most important step to making accurate ammunition. Is it bullet run out, case prep, powder weight consistency, bullet selection,etc... I have my thoughts on the subject and have cussed and discussed it with others. I want to know what y'all think, I know there is a number of very talented hand loaders on here. Tell me what you know and think.

Thanks.

Probably not one of the talented ones, but I used to think it was powder/prep. I think I am learning it is seating depth.

I don't think I can pick just one. I spend a lot of time working up the most accuate load. Trim length, neck tension, powder weight, overall length, seating depth, are some of the most important to me.

consistancy.

All the above to me and making sure I do not double load the cartridge, I check every load for the correct powder and try every bullet in the rifle.

Consistency in all steps must be there.
then:
Working up a ladder load,
1. powder selection
2. powder grs for best group
3. seating depth or depth to lands
for smallest groping.

I have to agree. Depending on what size groups you find acceptable will depend on how consistently you perform each step of the reloading process.

BP...

Although i don't reload i do think consistency is the key to having a good round.

I'm surprised no one has said safety...

Safety is important...but with regards to reloading, safety is a byproduct of consistency IMO. when you are consistant in every step, you are much safer. when you have a routine that you do the same way every time, reloading is pretty safe.

X2, well said.

I have never found anything unsafe about reloading. And saftey has nothing to do with accuracy. Unless you are an unsafe muzzle handler or do not follow directions well!!(LOL)
I would say making each load the same, no matter what you load, they all must be the same. So if you want to go with cosistency, I'm okay with that!
DUH

Also as far as your selections. All guns will be different so you must try every selection with every gun. That's where either the fun is or the downfall.

I think the bullet seating is critical, but have seen so many rifles w/ long throats and a boxed magazine. So, not very critical for most applications.

I also think powder weight is critical, but withing a half grain usually gets decent groups for some folks (not what I'd expect though).

Neck tension or turning isn't as critical as most think (unless your a match shooter). Not a necessary process for the everyday reloader.

Bullets are critical in some rifles, but the barrel twist rate depends on what you should use. Could be an issue, but usually not.

Primer pocket cleaning or reaming could cause some accuracy problems if the brass isn't inspected or cleaned properly, but not critical. I'm very particular w/ the pockets, but my dad and uncle have loaded as much as I have w/o ever cleaning or reaming them.

Case length is the most critical. If it's been fired once and it is too long for the chamber it's goin' into it ain't gonna fire/ chamber. So, this has to be the most critical.

Your question is somewhat off basis. There is not a most important step. It is the over all process done correctly, safely, range tested and coupled with proper record keeping. Any step left out, done wrong, something that distracts you within the process can harm your equipment and or change your personal life forever. Personal discipline and realization of excess within control is as close as it comes.

To me Texas Proud comes the closest to my experience. I think alot of what we get anal about is just that, being anal. I know I'm very particular about consistency in powder weight. I also know from experience that .1, .2, or even more, grains does not make much difference in overall accuracy. Seating depth of bullets can make a difference but again it can be limited by other factors such as mag length. I've never turned a case neck. I don't trim cases after every firing. But I also don't care if I shoot one hole groups. I don't always work up a load for accuracy. Meaning I'll pick a load below max and try it out. If it shoots good I'm happy. We all have different objectives for the reason that we handload ammo. I do it so I can shoot more. I was going to say to save money but we all know that don't happen . We just shoot more ammo them if we were having to shell out for factory stuff. I guess I'm a handload so I can shoot person instead of a shoot so I can handload person. Y'all posted up some great information, Thanks. Oh, and just so nobody gets the wrong impression I do believe safety is of utmost importance when loading ammo. I just don't think loading good ammo is as complicated as some people think, or make it. It's pretty easy to match factory ammo performance, although in the last several years factory ammo has gotten much better.

A chronograph. It will tell you when you are consistent. I went without one for far too long.

It will also tell you when you are leaving the safety zone. Most common methods of looking at brass, primers, etc., to find max loads are not very reliable and can actually be dangerous to trust.

Good point! I bought my first chronograph a couple of years ago. I bought my second one about 6 months later after my buddy punched a 44 Spl hole straight through the first one.
