Well I have tried them both and I am still getting lead traces in the barrels of my 45 ACP and 9mm.
What next? I suppose my BOOLITS aren't hard enough as they are made from mostly stick on WW with some clip-ons.
BUT they seem to shoot good. Funny thing is the same alloy shoots REAL good in my .357 mag. Using Unique in the semi-ottos and H-110 in the mag.
Is the Unique too fast in the Ottos?
I am sized .001" over in the .45. Don't know about the Maggie or 9mm grooves. Just sized .001" over nominal and shot them.
