high volume 303 loaders I have some questions

[CINDERS]

I tried Win-748 in my 303's and it was a dismal failure as I was going for a high density load for low pressure, you could try ADI's 8208 at 34gn (Min) with a 150gn Hdy SP 2,392Fps Source 6th Ed ADI Hanloaders Guide 2013 I am sorta off light density loads after a not to good experience using Win - 760 in my 6.5/284 which I wont repeat here the results safe to say I had detonations from flash overs and the primers fell out of the cases when I opened the bolt the events were not concurrent but 3 out of 9 rounds did this bad news......retired the rifle and grabbed my spare 308 as one should always take a spare rig to the shoot.
