I have heard this both ways from a variety of reputable sources, but thought I'd get some input from here. Can or will increasing the velosity of a given hard cast bullet actually lead a barrel less than a lower velosity loading ? I currently run a commercial, hard cast, 200 gr. RNFP bullet, sized .430 ( hardness factor not given & does not have a gas check ) from a .44 mag Ruger Super Blackhawk with 7.5 grs. of Unique that clocks about 900 FPS. Chamber mouths show no leading whatsoever, but the 1st inch or 2 of barrel shows light to moderate leading, nothing too bad . My question is this . If I wanted to push this same bullet, with 10 grs. of Unique for about 1100-1150 FPS, is it your opinion that the barrel leading would increase, decrease, stay the same, or are there too many variables to reach a conclusion without actually testing it ? I'd like a heavier load from this same bullet to compliment my lighter load, but at the same time don't want a heavily fouled barrel either . I have been reloading for almost 35 years, but have no experience pushing hard cast bullets beyond 900 FPS . Your thoughts , opinions, and experiences in these lines are appeciated. Thanks.
