I found several people using H335 for their 30-30 loads. Im shooting a marlin micro groove. I was shooting WW water dropped 170 grain .311 but they wouldnt chamber, switched to 309. I loaded up 23.4, 26, and 28 grain loads. 23.4 had some leading, the other 2 a lot of leading. THey were 1730 fps, 1967, and the third was about 2100.
Any ideas on why they are leading?
