I also do not know why everyone praises DT ammunition so much. I got terrible accuracy with the ammunition that I tried, although as everyone knows a good shooting load in one gun does not mean it will shoot good in another gun, but it may mean that the ammunition has a large standard deviation. I do not know for sure as I did not chrono them.

DT ammunition is the only ammunition that has given me "guppy brass." I will not shoot ammunition that IMO is loaded to too high pressures.

That is certainly a good/valid theory but any factory ammunition should be loaded so that it does not exceed SAAMI specs ( I would also think that they would want to load to a slightly lower pressure to cover their arse) when fired at any reasonable altitude, I would assume that sea level would serve as the benchmark.

[quote=mongo356;14511362]Nope. I did try a couple of different lot#'s to see if I maybe got a bad bunch. The nickel cracking was off and on, but the giant bulge was still there, to the point I couldn't re-load them.

You shoot 10mm out of a g20. I have a g29. Is there any difference in the barrel that would give you those problems and not me?
