"Whistler & Aspinwall - .30" propellant was sensitive to changes in  temperature and humidity.

I have wondered if this had something to do with the cracked lugs during the 2200 fps experiment. With all the discussion of 303 ammo and other heavy loads in Krags on this forum in the last year, why did they have the problem?
I know pressure goes up with temperature, pressures are MAP Maximum Average Pressure. Maybe the WA powder was really affected by 120F temps?

BR, did you get your copy of the 2004 GD?

I tried to straighten it out and it got worse and changed position. My computer is not working well today or I am not holding my mouth right. After 4 tries it is more or less as intended but still out of order. :-)
