I'll all but guarantee that 0.429" is too small for a Ruger. All the Ruger .44s I've loaded for needed 0.432" or thereabouts. Slug the barrel & each chamber throat.

Honestly, it doesn't sound all that bad. I've had worse leading. Shoot a cylinderful of jacketed bullets through the gun before you head home from the range.

Try the other lube also.

Lapping does wonders to cure leading.

New is not necessarily good for shooting cast bullets. The rifling is probably full of burrs and such from the manufacturing process. Same with chamber throats.

If you aren't going to lap the bore, a few hundred jacketed loads (clean out all the jacket fouling afterwards) will probably make it a lot more cast-bullet friendly.

Charlie,

Mike Venturio did a comparison with the Ruger Vaquero and a new Colt SAA a while back in Shooting Times. 5,000 rounds through each (.45 Colt, I believe all lead bullets). They were leading at the beginning of the test, but not at the end.

That may be the article you were thinking of.
