Hello Dave and Don,
that`s a new Info for me because i was the opinion that if more powder and power affect on the Bullets base it will faster expand .
but thx for this
will give a try to FFFg Powder from Wano / Schuetzen ( Sporting Powder) for this trial
have already used Swiss and KIK - FG and FFg and FFFG Grade before.
A friend just have very good results with this Sporting Powder in his Sharps and Rolling Block 45-100 but also in his Frontstuffer.
Clean Burn , soft fouling and good results.
will keep you informed
Klaus
