Trimming 223 brass today and had a user error while trimming.  I usually check every 10-15 cases but for some reason I wasn't even checking until I started a new batch.
Now I have probably 100-200 cases that are measuring 1.732 and up, will this still be okay to load up or is it time for 300blk? If your wondering it was from a giraud that had the die some how getting deeper towards the blade and trimming too much.

| 1.730" and up is OK. Neck tension will be less. May or may not be a problem. Check for bullet movement after loading an auto, before firing. SAAMI |
| IIRC, the trim-to length for .223 is 1.750. However, if you are using RCBS X-dies, I think they say to initially trim to 1.740, then just resize through the die for the life of the case without trimming again. Check with RCBS to confirm the trim-to length I provided. |

Myself, I wouldn't load them. But I have lots of 223 brass and high standards. Any case that measures less than 1.748 after sizing, I reform into 300 blk. Thanks I think I'll sell them for people to convert since I don't have 300blk. I'm using dillon dies btw. |
