Yep, in fact, the boys out at LASC (Los Angeles Silhouette Club), some of the 'leading' experts on lead bullet shooting, have a hardness - to - chamber pressure chart.   For our pressures of about 10,000 to 12,000 PSI in cowboy and Wild Bunch loads, they point out a 8 or 9 Brinnell hardness is just about perfect.   That is about a 2% antimony alloy.  Half Wheel Weights and half soft lead.   I find I agree with them boys.   It takes 12,000 PSI, according to this article,
http://www.lasc.us/FryxellCBAlloyObturation.htm
to make a bullet of 8 Brinnell hardness seal the bore.   And the harder the alloy, the more pressure it takes. 

Even on 45 auto slugs.   Too hard, and the hot gases blow by the slug and I get leading right in the throat of the barrel.  Haven't yet cast any slugs too soft to shoot well out of the 1911.  Keep going to a softer alloy every time I cast a batch. 

Good luck, GJ

Glenn Fryxell is a personal friend of mine. When he speaks cast lead alloy bullets, I listen! Most of his talk is too technical for me, though....

Vintage 2002 Rossi '92 Winchester, 45 Colt - 454190 mold, 250grs - Bhn13.5 or 15.4 -  lubed with 40:40:20 mix of mutton tallow:paraffin:beeswax -  Zero Leading with probably close to 15,000 BP reloads shot in the rifle.  Add also a comparable number of handgun reloads with the same bullet & lube ... still Zero Leading

...do they gunk up barrels or even damage them?
NO!

I have been shooting desperado bullets for many years, they are the only bullets I have found that will fly straight and true from my circa 1995 over bored rossi 92.  .434-5 groove diameter vs .429 spec.  Hard Cast bullets don't group less than 5 inches at 25 and many keyhole.  At 50 yards much higher incidence of keyhole.  The desperado bullets fly true shoot about 5 inches at 100 with round holes.  I do not get leading in the rifle.
