I haven't shot any of the 501s. that will be probably next weeks project but I did shoot a bunch of 9mms yesterday out of my ar15. What I shot was 4 different bullets both coated and lubesized. All were cast out of an alloy slightly softer then #2 and all were water dropped. the lubesized ones out of the mold and the coated out of the oven. All 4 were around 120 grain so they got the exact same load. Same primer, same seating dept. What I did first was shoot all 8 and narrowed it down to the two most accurate bullets. While testing the original 8 loads only two were more accurate coated and both of those loads didn't make the cut. Out of the final 2 bullets (4 loads) id say the conventionaly lubed bullets edged out the coated ones by about a 1/4 inch at 50 yards. Now this sure isn't scientific. Its only one gun, one primer and one powder charge. I was just wondering if anyone else put the same bullet side by side with the same load in the same gun to see if they saw any difference???

Let the coated age longer, I suspect that the age of both coated and lubed were different.

I commented on another thread (lubing coated bullets) about this in 45 acp i found little difference between coated and conventionally lubed bullets, Velocities came up identical .
