I will be working W seating depth tuneing next. Powder charge really matters though. Went out last evening & tried 5 shot strings at 30.3 gr & 30.5gr for telling results. 29.3 put 4 into half an inch with a horizontal flyer that opened things up to roughly 1". 30.5 grains was over a 1.5" group.
As for velocity we will need to keep in mind that I am substituting BR4 primers for Fed 205's & this barrel tends to be a fast barrel anyhow. 29.3 gr of CFE 223 was averaging 2980 per Lab Radar from this 22" Pacnor barrel. As I recall the velocity variation was within 15 fps on the 3 shot load test. Was late when I arrived at the range last night so I had not used the Lab radar on the 5 shot strings.
