need help relaoding 223 rem Sellier & Bellot

[phishroy]

Need some advise in relaoding 223 rem Sellier & Bellot cartridges.
After I resize them they just wont fit in my chamber.
Cant figure it out. Any one have any experience reloading these.

I haven’t seated a bullet or even a primer in. I tried full length resizing and neck sizing. Cant get them to fit my chamber.
I have some factory loaded S&B which fit my chamber no prob’
Any one have this happen to them? Any advise as to what I should or can do.

All the other brands fit my chamber after resizing using the same set of dies with no problem if that info helps.

Advice needed.
Thank you.

All I can say is make sure your sizing die is adjusted properly, & that you are completely resizing the case. Also check for for proper case length. If you have a digital caliper you can measure the cases & see if there is a problem. If other cases fit in your chamber after sizing, the S&B cases should fit also.

Screw S&B and just collect enough LC 5.56 ammo from your range floor.
You'll have to ream the primer pocket or just chamfer, but you'll end up getting excellent quality brass, that will reload many times in your bolt action if you just neck size.

And don't use Lee neck sizer - it's so dependent on the force with which you work the press, that you'll never get consistent accuracy.

I don't see how the brand of brass could lead to this problem. Either it's being full length resized correctly, or it isn't.

As said above, check your dies.
