My best advice to a new reloader, in addition to everything stated above, is the following:
Regardless of what dies you end up buying, make sure to still pick up and use a Lee factory crimp die. Use it as a final step. Consistent pressure curves and consistent neck tension= better accuracy. Regardless of where you are in your powder and bullet and bullet seating depth experiments.
The basic process, in short:
- Case cleaning
- Case resizing (and then trimming if needed)
- Priming
- Powder charge
- Bullet seating
- Lee factory crimping
- Check final overall length and ability to chamber in your rifle before loading 100 rounds that don’t fit…
Just a few Aspects of those steps that affect accuracy/ brass life/ die performance:
- Case cleaning: decreases grime and particles that make it into your resizing die. That makes resizing cleaner and more consistent. Also this makes your reloads look nicer!
- Case resizing: in terms of accuracy this can be a deep rabbit hole that might be a bit too much for a new reloader. In short, your cases are already slightly optimized for your rifle just having been fired in it. You need to choose how much more to “work” them. Neck sizing or barely “bumping the shoulder” could yield accuracy gains and increase case life. It could also result in an overall larger case that is now out of spec enough doesn’t chamber in the moment of truth. No amount of accuracy or case life is worth that, so maybe for the beginner a full length resize per the die instructions is the best place to start. Also, A case that is longer than SAAMI maximum length is an easily identifiable hazard and should be trimmed or just thrown out if you’ve gotten acceptable use out of it.
- Priming: Consistency is relatively easy here and can yield accuracy benefits. Look for match grade primers if available.
- Powder charge: Easy to experiment with this and accuracy differences can be impressive. Good reloading manuals list their most accurate powders and charges for any given bullet weight. These are good powders to target. To a large extent pressure= velocity. Therefore, a chronograph can help keep you safe from too much pressure. If you are getting more velocity from a given power charge than is listed in the book, and especially if you are over max listed velocities for a given powder, don’t push too much higher unless you really know what you are doing. The “My .308 WIN is pushing 180 grain bullets to 3000 FPS with NO PRESSURE SIGNS” guys are asking for trouble.
- Bullet seating depth: Consistency here is huge for accuracy. And don’t be fooled by polymer tips on bullets. Your die might be seating the bullet consistently, but you keep playing with the die because inconsistent polymer tip sizes make it look like your overall length keeps changing! It’s probably not. Anyway, variations in seating depth is also an easily modified variable that can influence accuracy. But I’ve found the suggestions in the manual for overall length usually yield good accuracy.
- Lee factory crimp: as per above. This is WAY easier than using your bullet seating die to apply a roll crimp.
- Many handloaders cycle every single handload through their rifle before going to the field with it.
My 30-06 Hunting Load is pictured below. I get a little into labels, but it makes the next round of reloading real easy. To end up at that finished product, which shoots consistently 1/2-3/4 MOA, I tried: Different bullets, then when I found a consistently accurate bullet, I tried different powders, different powder charges, different bullet seating depths, and two different types of primer.
