Not really a problem, maybe. I've been working on a 30 cal and got it to where I was pretty happy. But, I ran out of bullets. I bought the same kind from the same manufacturer, same part number, same weight, etc. But the length is way different from the original. Not talking, one or two thou, or even five thou. What I consider a substantial difference of twenty thou. To me, this signals that the form factor may be significantly different from the original, which would change the BC, but not really concerned about that as this will be an intermediate long range load, say out to 500 yards. What I am more concerned about is how much this will change the harmonics/accuracy.

I have loaded three rounds so far, set to length by the ogive. This is where the discrepancy showed up. Even though the new loads are set to 8 -10 thou off the lands, the overall length is short by about 16 - 18 thou.

I even went as far as making a new "dummy" case to check my jam length. Sure enough, 19 - 20 thou short.

So what was supposed to be a final test/confirmation/sighting in day at the range, is now taking six rounds and seeing what happens. Frustrating to say the least.
