Is this step necessary? Does it improve accurracy or is it a waste of time? Your thoughts please before I invest in another item.
thanks

BigBrass, There are group size comparisons published on a regular basis. They are called "MATCH RESULTS" You can very readily tell the shooters that do a complete "match prep" on their brass from those that skip a step or two. The ones that do it all will be listed in the top 20 or so. The rest will be listed immediately after those that pay attention to detail. Jim

robz,
When I first started handloading, I didn't uniform the primer pockets nor deburr the flash holes (maybe just different terminology, but I'm not sure which of these two different steps is the equivalent of "flash hole uniforming" you asked about ). Over the years I read additional handloading material. I now routinely carry out both these steps (as well as checking for case neck uniformity) on all my non-revolver loads. After I'd been doing this a few years, I decided to do my own testing to see if these additional steps improved accuracy or just took up my time. Bottom line--accuracy gradually improved w/ each step; individually the improvement was small, but the cumulative effect was noticeable. I use the Sinclar tools. Sinclair also has a very good handbook for about $12 that goes into a lot of handloading details not normally covered by the handloading data manuals. I'd recommend you add these steps to your handloading process. Gary T.
