10 Gauge 2 5/8" Load Results

[Mark Garrett]

The difference in pressure is because of the hull length and the use of soft filler wad.

Here is the information sheets from these two loads. I did individually weight out the powder and shot for these loads.

Not likely. The tested loads are not identical, the 2 5/8" load used a Cheddite hull, the 2 7/8" load used a Remington hull. I will wager use of the same hull will show closer results in pressure.

I would say very likely , yes the change in hull will change pressures also . The testing I've done shorter hulls always produced more pressure . Tom Arburst told me less space for gas to expand = more pressure .

Also with the testing I had done using TSS , which always required the use of fillers , the more soft fillers ( felt , cushion wads ) = lower pressures and less consistency . As opposed to harder filler ( Nitro cards and cork ) = more pressure .

But don't take my word for it you can always call Tom Arburst , he can explain it better than me.
