Sorry, incorrect title, it is the 457193 mold!
This was a comparison of two bullet types with the same smokeless AA5744 low pressure powder loads, almost...I had .2 grains more in the Powder coated bullets. (26 gr vs 26.2)
Mind you, I was testing velocity first, and accuracy 2nd. I didn't see much difference on accuracy at 100 yards.
The biggest difference I saw was when I cleaned the bore after 10 shots of Powder coated and non-powder coated. Much cleaner barrel on the PC bullets. Makes sense though, no lube on PC bullets!
Rifle: .45-70 (1883 cartouche)-Trapdoor with a .458 slugged bore diameter.
Bullet:Lyman mold cast 425 gr bullet-(457193) powder coated- Sized to .458
Powder:AA5744 26.2 grains
Primer: CCI Rifle Magnum
Notes: EXCELLENT Spread on the velocity.Cleaner bore than lead bullets after shooting 10 rds. One "Hole through hole" shot.
