The prices are lower than they are in Germany.
Overall, very good powders widely used here.
N110 is very similar to the Hodgdon H110 (we use N110 for .357 Mag & .44 Mag); N140 very similar to H4895 (used for 6.5x55 , .308 , 8x57 IS).
9mm Luger loads using 125 grs FMJ, WSP primer, OAL 1.142" (29.00 mm) are:
by SAAMI specs.: 3.7-4.3 grs N320
by CIP specs.: 4.0-4.7 grs N320
A friend loaded mine with 4.3 grs for my P08. Flawless function, very accurate.
