Up to this point in my life I've worked up some decent loads in my revolvers using both off-the-shelf boolit molds and semi-custom molds from Accurate. In an effort to squeeze every bit of accuracy out of my revolvers I'm curious about two things that might tighten up accuracy even more but I haven't found much written on the subject. One thing is to only neck size brass so the cartridges have a tighter fit, and the other thing is to order a mold with a longer front driving band for the SWC's I shoot so that they enter the throats by a few thousandths of an inch. I think either of these steps would improve accuracy to some degree.
The only downside I can think of using either option is in heavy recoiling revolvers where I'd worry the cartridges might be pushed back ever so slightly causing the cylinder to lock up when attempting to re-cock (SA's). Has anyone used either of these methods to improve accuracy? If so did you have any problems seating cartridges or with the cylinder binding? I'd appreciate any info or opinions.
