Got some time to test the PC'd Lee 250-FN in my 38-55 yesterday and today with chronographed velocities.
24gr R7, 1465, 1409, 1441... 25gr R7, 1555, 1516, 1488... wide variation, left unburned powder in the bore. Next was some Unique loads with 10gr, these were not pc'd but run thru my lubsizer, 1209, 1204, 1205 much cleaner barrel but had some leading. Today was with A2400 and pc'd bullets , 19gr 1577,1576, 1572 and clean burning. Very minimal leading, just a couple small particles on the first patch,:smile: Pc'd bullets were sized to .377. The 2400 and unique was also the most accurate, 1 1/2" at 50yds
