Re: Casting Your Own Bullets
Back when I started casting my own bullets (about 1973), I bought an RCBS Lubri-Sizer. I slugged my barrels and ensured that all my bullets were sized to 0.001" over groove diameter.
After using the god-forsaken LubriSizer for about a year, I read an article in Handloader about shooting As-Cast bullets.
I then cast a bunch of bullets and measure about 20 randomly to find the largest diameter and bought a sizing "die" in 0.358" for my 9x19 and 0.453" for my .45 Auto.
I then started comparing "as cast" (since the sizing die was not touching more than maybe 5% of the bullets) and sized. In almost every case, for difference cast bullets and different powder charges, the as-cast bullets were more accurate.
I haven't really sized a bullet since then.
When I read about pan-lubbing, I started doing that and only used the LubriSizer for lubing rifle bullets (7mm TCU and .30-30)--again, with sizing dies large enough to just barely kiss the occasional bullet.
When LLA and tumble lubing came out, I started doing that.
Currently, I haven't been able to maintain my lead supplies so I have been buying commercial. I am every so tempted to have them ship me as-cast and non-lubed bullets, but I am just getting too old to worry about the increased accuracy and prefer to spend the time I have left shooting.
I have really only read about so many die-hard bullet sizers in the last few years--most of whom have never tried as-cast bullets and assume that sizing somehow makes all their bullets more consistent and ANYTHING that is more consistent is ALWAYS going to produce better accuracy and will not even consider trying anything since they KNOW it can't work.
