Re: Looking for some bullet help/advice
Quad-F in the pan is good. Double-F as a charge powder is good. That's all I've ever used since 1980 when I started doing this.
Try the Hornady Pa. Conical. It's an all lead 240gr. that does not require a patch. I load 'em with a T\C bore button in between the powder and the Conical. Also, Hornady packs 'em with a ton of lube. I scrape all that lube off.
Or, for the same result, without the need to scrap the lube, use the Buffalo Balletts. Same results as the Hornady's. Identical POI.
Your 80gr. of powder should be fine. I shoot 100gr. I have shot these from my old T\C 1-48 twist barrel, but I now have a Green Mt. 1-70 twist.
