[QUOTE="Tac-O, post: 2723171, member: 109994"] I wouldn't say it's an issue.. just more growth per cycle than I expected. Yes, 7th load all from same chamber. That is including the fireform load. No signs of case head separation yet. No indicators on the outside and I looked inside with my borescope and don't see anything. I still need to feel inside with a paperclip though. Here's my process. I'm using Peterson 284win as the parent. I first expand the neck to .308, then load a round that is near the lower end of charge weights for 30-06. My chamber is set up so that I get a crush fit per the AI forming method with a virgin 284 case. I can't remember exactly what the length is after necking up, but it starts around 2.160 virgin, gets shorter necking up, and a bit shorter fireforming. After fireforming case length is around 2.146 and after sizing the length is 2.150. My chamber is 2.172, so I try to keep brass length to 2.162. I can't remember for sure, but I think the first time I trimmed to 2.162 was after the 5th load... It was at about 2.167 before trimming. [/QUOTE]
