Shamu: H335 is for top end loads as it needs pressure to burn correctly. Kind of like H110 doesn't work well in down loaded .357's or .44's. It is the goto powder for loading top end .45-70 ammo with Jacketed or Solid Brass Bullets. Also rounds like .308,.30-06 .223 all of which would normally produce more pressure than a .303 and especially a down loaded .303.

I think low pressure is likely the problem here as it appears you have eliminated case contamination.
