Updated data with BP1044 wad.
Hers is some data Tom Armbrust and I put together with Tom's permission to post it here.It mostly involves the new BP1044 10 gauge wad from Ballistic Products.If any of you have tried these wads yet you will notice they are a bit smaller in diameter than the SP10 wads and therefore is a chance of powder migration in certain hulls with certain powders.So I sent Tom a bunch of hulls and components and he assembled them for me trying different gas seals beneath the wad,over the powder.The loads with a X10X wad,same as a GualandiGS10 gas seal really performed well with very little variance in pressure or velocity.We also tried some with a discontinued Alcan PGS gas seal,and some with a nitro card beneath the wad for reference.Tom also fired a few vintage paper factory shells he had on hand for reference.
