Hi Ray,

1. Normally a roll crimp will lower peak pressure. Be careful not to make the roll crimp too strong since that may raise pressure higher than a folded crimp.

2. A Win 209 substituted for a Federal 209A will normally lower peak pressure. Since the powder still burns and produces roughly the same units of pressure but over a longer period of time the velocity will only be reduced slightly.

Start with the lowest pressure load you can find. That way if you make a slight mistake you will be safe.

Load safely,
Mark
