Is there anything to be gained

[427Cobra]

I uniform all my rifle primer pockets and deburr the flash holes with Sinclair tools, ultimate rifle accuracy means lots of case prep, but on my pistol rounds I don't do any of it, my G35 minor load does 3 inches at 25 yards from sandbags, would uniforming the primer pockets and deburring the flash holes help any or is it just more work than it's worth.

I think most reloaders for IDPA/USPSA would say it's more work than it's worth!

Two ways to find out.....Do it and see for yourself.....Or, doi a search on here and find out, must be 20 threads asking the same question....Either way, you will find the same answer....waste of time....

Well B.E. aka before Enos Forum I shot 4" targets at 35 yards in 40 cal = the gun is up for sell in the classified now. any way I did the entire set up = Flash holes & brass sort to bullet groups by weight.

shot groups off the bench as 35 yards and as much as I wanted it make a difference it did. I knew that the "ME" shooting the group paid more attention to the long prep loads than the groups shot with the mixed brass loads.

So If you think it will work Thin it more than Likely will,

But if you try and prove it to a buddy your groups will go to crud so. If it works you have to keep it a secrete for it to continue working.

not only a waste of time(we typically shoot at a 9x12 inch A zone) but when you concider that at a typical match you see less than a 10 percent return of fired brass off of a stage(least i do anyways, been calling the local matches of late 'lost brass matches' because of the lack of returns) you will cry at the time and effort you put in to that braas only to lose it...save all of that prep timefor boltgun brass, somthingyou can get back and re-use hehehe

Once you've found the load you/your gun likes the best, I've found the best accuracy to be with new brass, or, once fired brass, out of the same gun.

I stopped doing it for my 204 and 223 and can't believe I ever wasted the time to do it to begin with

nothing has changed not a dang thing

OK, here's the skinny on that kind of brass prep, I'm a Master Class PPC shooter, we shoot out to 50 yards in matches, the ONLY special thing I did on match loads was to use only one brand of brass. For practice I used mixed brass, but for match use the brass was inspected a little more carefully, and I only used Remington brass.

There is a 99.9% chance that your pistol can shoot better than you can possibly perform as a shooter, so extreme efforts in brass processing will gain you absolutely nothing on the target. Make your loads as reliable as possible, but things like uniforming primer pockets to supposedly gain a tiny amount of accuracy are a waste of time and effort.

Never saw the point of it, in either case of long gun or hand gun the gun always seems to shoot better than I can so I don't waste my time. I will say to me more important than worrying about deburring flash holes etc... is just to take time to inspect inside and outside of cases especially if pick up range brass. I had gotten slack on this and just happen to notice while loading on a dillon 550 that a 9mm case looked way to full for 1 pull. Dumped the powder out and there was grass compacted in the case that the tumbler didn't get out. Loading with titegroup that would have caused a problem for sure as the powder was near the top. Thank goodness I just happened to be looking in the cases after the powder was dumped.

When I shot PPC, al of the above but I used Federal brass only.

I do prep my bolt action rifle brass when needed.

A waste of time and effort for pistol.

Precision rifle is where you get the most benefit to squeeze all the accuracy out you can. With USPSA loads, I don't find it gains anything with all of the movement the body does during a stage.

Did you ever experiment and determine if ANY of your case prep actually made any difference on target?

Note: most case prep MIGHT shrink a group by 0.1", but I doubt it. What does that mean for a 3" group? Will you really see a difference with 2.9" groups?

... to add to this and from my experience shooting the sport, most top group Benchrest shooters, even those who have demonstrated the skill to actually shoot a .100 group, yes, that is a measured .100 group, never touch a primer pocket or flash hole. That is just not where it's at, even in that game.
