Just a quick FYI..........
In order to compare the "clean burning" characteristics of E3 and Beye, I loaded 6 rounds of Beye (5.5 grains, 200 gr. Xterme plated FP, Fed LP primer, OAL-1.230)
and 6 rounds of E3 (3.8 grains, 200 gr. xtreme plated FP, Fed LP primer, OAL 1.230).
I then fired 6 rounds of the Beye load throught my previously cleaned 625JM and closely inspected the chambers, barrel, under the extractor, and the empty cases for unburned powder and debris. As expected there was almost no debris found.
After cleaning the 625JM I fired 6 rounds of the E3 load, upon inspection almost no debris was found.
Granted 6 rounds doesn't tell much but at least I can now expect that the E3 powder won't be any worse than Beye.
No chrono data and no accuracy comparison yet.
