Have a dilemma and can't solve.
I have been reloading for a very long time and very successful at it,......for the most part. Shot in many competitions with my reloads and have done well. Reloaded 30 different calibers.
My one issue is 338 Lapua. I have been fighting with it for 15 years. Not accuracy but the cases don't seem to resize near the web.
Factory new case is around .5830" just north of the extractor groove . It tapers down to .5770 at what I call the web, about .1750" from extractor groove.
A once fired case (factory Berger) has the measurements at .5830" and .5820" at web. A growth at the web of .0050-.0060. No problem there just fitting the chamber. The problem occurs after second firing. That web area expands(bulges) again out to .5840-.5850. Once they get to .5850" they don't chamber without a fight. Extraction wise I have to smack the bolt to get them out and take some light force on bolt to push down.
Now this is with very light load like 92 gr of RL-33 or 85 gr H1000. Even heavy loads I have exact same results. Using berger and Lapua 300gr Bullets makes no difference. Loaded .02" off lands.
I have the Redding Type S Match reloading dies. Full length and body only. Same results with both. It doesn't resize this area at all. Shoulder gets bumped perfect but that bulge doesn't go down. The dies and the press (Rockchucker) are the only commonalities in this whole thing but there are 2 different ones giving same results(dies).
Things I have tried. Bought a newer Desert Tech , competition shell holders, annealing, different lubes, over camming, and probably many others. Most frustration thing ever as It shoots lights out and I have had it out to 2470 yards. Just cant use the cases past 2 or 3 times depending on how much it bulges.
Put sharpie on bulged case and it definitely catching (tight) right at the web.
Do other peoples dies resize in this area??? Is it simply that i have 2 bad Redding dies??? Was going to buy a foster and try next.
Any help would be much appreciated. This is very frustration and getting expensive buying cases every 2 or 3 rounds.
This picture is after I overcammed the hell out of the press just trying stuff. The arrow points at my problem area that doesnt resize at all.
