As long as I have access to the Greatest minds in reloading here is my question.
When reloading (non boat tail) pills specifically .308 and .311 how do you get them positioned to go straight into the sized neck? With straight wall we expand...is there a rifle cartridge expanding step I'm not aware of?
 
The decaping stem in the sizing die has a button just above the decaping pin that expands the neck on the upstroke.

Seating flat base bullets can be tricky. A good inside chamfer of the neck will help alot, especially if you use a VLD taper chamfering tool.

And alot of newer rifle cartridge seating dies incorporate a sliding sleeve (like high end competition seating dies) that hold the case and bullet in alignment on the upstroke.

You either need to flare the case neck OR chamfer with the RCBS deburring tool AND carefully set the bullet in as vertical as you can and seat carefully.

I do this with flat base bullet I use in .30-30 loading (.30 carbine bullets) and do not have a problem.

Ditto this however and I would never buy any rifle dies in the future without this. I have one set now (.223) and it works very well.
 
it in fact allows for tension on the projectile right??
Yes and like I said above;

I made a flaring tool to flare .30-30 case necks to seat lead bullets as flaring is necessary to properly seat them.

I think Lyman has an "M" die IIRC which can help immensely with this issue.

Heavy chamfer (as mentioned)

Bullet seating die with a sleeve (my go to is the Forster competition bullet seating die).

As mentioned, it's a lot more critical to place the bullet squarely on the case mouth.

I had to deal with this when I first started loading 34gr FBHPs for the .223
 
I load lots of 30 cal flat base. Never needed anything different or had issues. I wouldn't want to bell the cases. Belling sometimes doesn't help with holding the bullet upright before seating, it would require an extra step of crimping and I don't want to over work the case mouth.

I do use a 30 carbine expander/belling insert in a longer die body for loading lead bullets in 30-30 or 30/06. That is necessary to prevent shaving lead off the bullet.

Yes, the Lee expander pinned above is recommended for cast projectiles.
Ok it sounds like I'm doing it correctly, maybe a bit more chamfer.
 
Once a bullet enters the die, it gets aligned before seating, wether it has a floating seater or not. You only need to get it into the die.
Depending on the bullet base edge, any chamfer or belling may not be good enough to reliably hold the bullet upright. Sometimes you just have to be careful to ensure the bullet starts into the die opening. I have certain pistol bullets that do not stay in placed no matter how much or how little belling there is.

The degree of alignment is what is up for debate.

I've shaved off more copper rings than I care to admit. The sleeved seating dies help immensely with this.

Flat-Base and with a inside mouth Chamfer of the Neck , there nothing more you need ....BUT

Is it new Brass ?? .. or , If you reloading fired Brass . having problems seating Flat-base with stiff seat, and uneven alignment .
People always disregard the fact that Brass Necks Get Brittle and less Flexible ' No Stretch ' with X-amount firings . You need to Anneal and then keep on reloading your brass until your primer pockets are blown.

Both new (Starline) and used brass.
 
When loading 300 BLK subsonic, I have used a hi tek coated, flat base 220 grain bullet. After initially having difficulty seating these bullets in sized or new cases, I use the Lee universal expanding die you linked to slightly flare the case mouth. After seating with my Forster seating die (with the floating chamber), I use the Lee FCD to remove the slight bell/flare. This process has worked well for me in this application with coated lead, flat base bullets that are probably on the larger diameter for the expander on the sizer die that were difficult to seat without shaving the coating/lead on a sized case.

One day I'll be as smart as you all!
