With 115 gr bullet and Bullseye, 4.7gr is my field load (HK P-7, works great on turkey). 4.8 is absolute tops. If using a GOOD powder measure and technique, I would stay with 4.5 or 4.6 and not have to worry about working too close to the edge, especially for club shooting ammo. Hornady and Golden West 115's with 4.7 feed fine in everything tried. Reliable, that's the word. Accuracy is consistantly good, maybe not always the very best but consistant. 115's help consistantcy. 124's too slow, work OK in most guns. 90's and 100's very load sensitive. My friends' Glocks don't normally like lead bullets. Polygon rifling. Try Golden West, Montana Gold, and Berry's plated, all are nearly as cheap as cast.
