It can happen - :)

here's a little something that happened to me...

Decided to test with some nice FMJ BT with Cannalure .308 and TRAILBOSS powder out my FAL set to single shot Grenade setting on the gas position. This is the same Rifle as used with Cyclone on previous tests.

As there are only these 3 orginal cases I decided to take my reloading to the field so purchased some little glass vials to preload with measured bits of TRAILBOSS powder. As David had already tried 10 grains with his loading and it filled the case to capacity and was a compressed loading. I discovered that 8.5 grains was to the base of the bullet and started there.

Used CCI 250 magnum primers
Velocity figures
1160 - 1009 - 1128
Target 1

This was the 9th loading of these solid brass reduced capacity cases
- no neck splits or other problems notices with the cases at this time.

On thing that was noticed, was there enough gas blow around on the cases caused me to have to clean the chamber (dry brush) on the FAL or it would fail to go all the way into battery until cleaned.
