    i have been reading alot about having more powder in the brass cartridge ( reloading 45LC ) seems to be the best possible advantage to better burn / velocity / accuracy....

    if my recipe calls for only 6.0gr compared to another powder at 11.5gr....are there "fillers" one can use to get more volume or is it best to try the larger volume powder?....it seems the burn rate of the higher volume powder (v-340) is just alittle faster them my current powder (Titlegroup)...

    If I could find reputable load data made using fillers, I'd consider it. Otherwise, it's better to switch powders. Adding fillers will increase pressures.

    Titegroup is advertised as being insensitive to its position in large volume case. If that's true, fillers shouldn't be needed to get uniform velocity.

    you forget to mention safety. If the powder you are using almost fills the case, it is impossible to get a double or triple charge without noticing.

    Another benefit:

    Large capacity cases using modern smokeless can sometimes be "position sensitive". The small charge gets into varying places and thicknesses inside the case and can cause consistency problems. A larger volume solves this.

    Also don't forget that weight and volume are two seperate and different things. The fluffier powders take up more space per weight grain than the more solid ones.

    Unique is often preferred in .45 Colt because it fills the case better than a comparable charge of, say, WW231.

    If you want a "fluffy" powder for .45 Colt try IMR's Trail Boss. It does a good job of filling the case. I've tried it, but I still like Titegroup better. I think Titegroup must build pressure quicker because my fired cases don't seem to be as sooty.

    I've never tried Unique, but I understand it is "the powder" for .45 Colt. I just can't get past it's reputation for poor metering so I haven't bought any.
