[QUOTE="bigsampson, post: 478640, member: 28753"] This issue IS related directly to neck sizing. The amount of case capacity lost from neck to full length resizing is miniscule. The loads I am using are 2 grains or more under the lowest max published, are very standard 338 LM loads and function perfectly fine in full length resized cases. In several cases, dealing with 250 grain bullets, the load is even lower than two grains under max. I see this issue when reloading 300 grain SMKs and several other 250 grain bullets. Not talking about unusual powder either. Retumbo, the "go to" 338 LM powder. OAL isn't the problem either, not even close to pushing this. I think Rockz is probably on target. [/QUOTE]
