Loading in advance?

It seems to me that your use of wax may prevent what I, and others have called cold welding.

SO if I getting this right your experiencing this POP"N noise when re-seating the bullet?

I have some 9mm and 45ACP loaded in august of last year, I may try to see if a few of them may make a noise if so.

I only use the wax On my long range competition rounds, .223 and .308 and I load them by the 300's 1 month supply in case I change my mind on the load. My Silhouette loads in .223 (no wax) by the 1,000's. I have lots of those to test too. I'll post a photo or two of my pressure testing.

300rum - my symptoms could be characterised as the following;

A loud "pop" is heard along with much higher Initial hand pressure when seating bullets deeper that have been seated .010 off the final seating depth and they have been seated in the case for longer than 1 week.

I just loaded up 4 dummy rounds with polished necks (inside), no wax on bullet just brass and copper. Over the next month I will attempt to reseat one bullet each week, and come back and post the results.

Thanks - to me the two questions are;

1./ Does it cause increased chamber pressure
2./ Does it affect accuracy

It could be debated as to the usefulness of knowing the scientific cause (outside of curiosity) as we have anecdotal evidence of ways to prevent the symptom from occurring. Again anecdotally point 2 is answered on this forum (however discipline context is not necessarily provided) and in my experience in terms of F-class accuracy requirements I have been unable to determine a difference. A short range benchresters requirements are quite different so the accuracy question is relative.

Point 1 is of interest as I sometimes wonder if guys call a load too hot simply because of the "weld" (for lack of a correct term) and in reality a change in timing of when the bullet is fully seated would solve the issue.

As a point of interest I experience the issue with "dirty" necks in either an annealed or non annealed state.

i have had this experience and discovered it when muzzel velocities were in excess of prior testing with the same load. the prior small group was gone. i'm having the same problem now with loads one year old and later today i'll try seating these .005 in deeper...i anticipate a pop since this load, when fresh, was a one holer. to those who state that loads in excess of one year still shot accurately, how many were loaded to jam into the lands? if this is the case, chambering the round into the lands will possibly seat the bullet a few thous, thereby breaking the "weld" and restoring the bullet/case neck tension near to it's originally loaded state. my misbehaving loads were all loaded to jump. in the future, such loads , if to be shot later, will be seated long, to be permanently seated just prior to use. this phenomenon has a scientific explanation, once discovered, can be explained such that we all can understand.
