Thanks again for turning my picture thread into a place for you to tell your sad little story.
I think you have attempted and failed to explain it accurately.
A quick example is right here. "To call my reloading practices shoddy" is a bit of a stretch.
No one said that. I said "Which tells me this guy is not well versed in reloading." and "I think he doesn't know as much about reloading as he thinks."
I think you are exaggerating the story because you wanted a free barrel and you got you panties all twisted up when they wouldn't play your game.
I am not going to continue discussing this with you. I am also not going to keep asking Ron about anything.
I think your full of crap. Here is why:
I found this in one of your older post. Sounds like you had your problem figured out to me.

Sounds like I need to get some new brass, and run a powder with a published load.
<span style="color: #FF0000">Yes, excessive case head expansion is one of the most definite ways to determine if you're running too hot.</span> In my experience, the 338LM doesn't show a lot of the conventional pressure signs (flattened primers, difficult extraction, etc) <span style="color: #FF0000">until it's really too hot or after you've put several hot reloads through it.</span> <span style="color: #FF0000">I can't really explain why this is, but I'd guess it could just be a really strong case that can tolerate a lot of abuse. </span>
Like PGS suggested, I'd recommend going with Lapua brass; run just a couple cases (5-10) for several firings and see if it shows up again. I'd hate to see you prematurely wear out 100 Lapua cases with the same problem.
Good luck!

I can't follow your logic, but yes casehead expansion is a way to determine if one is experiencing excessive pressure. However, if you read my previous post carefully you'll see that I was experiencing expansion of the body of the case at a beginning load of 85gr of Retumbo, and difficult extraction at 87gr behind a 300SMK. That is an incredibly mild load, max charge is 94gr in nearly all reloading manuals.

This is an exception. His problem is over pressure and is trying to blame benchmark. If your not an idiot you have nothing to worry about. </div></div>
My problem was NOT over pressure. Once again, please read my previous posts. I did a test with virgin Lapua cases between 85 and 94gr of Retumbo behind a 300 SMK. ALL cases above 87gr had difficult extraction on the second firing and beyond. 87gr of Retumbo with a 300SMK is a mild load. Additionally I experimented with 250 Scenars (with 4831sc) and they too showed difficult extraction at mild loads.
I know the Hull brothers aren't listening to what I'm saying here, but I did my homework and experimented with different dies, bullets, brass, powder, and primers before arriving at the conclusion I did. At that point I brought it to Benchmark and asked for their help in troubleshooting; they couldn't explain it either and blamed it on the "Semi-Auto" 338 Lapua reamer.
I don't appreciate being referred to as an "idiot" nor do I understand how my attitude is offensive? I am just explaining what happened here and the Hulls refuse to use reason or logic; they are simply assuming I am wrong and that Benchmark is right. I am willing to let this die as long as you two don't make false claims about what happened.
My story is pretty straight forward, if anyone has any specific questions please PM me and I will be more than happy to discuss the details.
