I believe the funneled flash helps to lower the chamber pressure but I'm Polish, so what could I know?
This makes MUCH sense. I have a flint lock that I have "coned" the flash hole on both the outside and the inside. It makes the flinter go off much much faster, and also more reliably. I have never thought of doing to brass, but now you've done it...

I do careful case prep. I've gone the "cleaning primer pocket & flash-hole prep" route. Believe me when I tell you, it doesn't make a difference.

lloyd smale been loading for 45 years. I cleaned primer pockets and flash holes for about the first year and haven't done a single one since. To me its about like trimming handgun brass. Maybe id address it if I shot bench rest comp. But with your measuring groups with a ruler it does nothing. But I guess if your bored or enjoy it----. Me id rather spend my time shooting.

mdi A few terms have been tossed out on this thread. Cleaning flash holes to me is removing and debris from the hole itself. Uniforming to me means using a tool, often a reamer type tool to cut all flash holes to the same ID.And deburring is often done with a different tool that cleans and chamfers the inside and/or outside ends of the hole itself. The OP's pic shown brass chips/cuttings so I would guess he is talking about deburring the ID of the flash holes. One time I was really bored and I deburred a bunch of my 7.61x51 LC brass' flash holes...

land_owner Never used to, then got an RCBS case prep machine with its five rotating stations and it became one of the 3 second actions to clean the primer pocket as were the other 3 remedial mechanics of case prep with the machine (inside and outside chamfer and mica inside neck lube) - 15 seconds and done.

[UPDATE] reason for this Edit ==> mdi is correct below. "Flash hole" is the subject of the OP. I got lost somewhere in the terminology/previous posts and responded about the PRIMER POCKET.

DEACONLLB I would think that one of those welding tip, cleaners would work great I use one to clean the breach plug on my muzzleloader The one I have has about 10 different size cleaner tips.

The Old Man Anything you can do to get things as close as possible to the exact conditions of the previous round(s) is going to help....alot.

When I had my 22/250 for long range groundhog I trimmed, reammed, uniformed flash holes, kept track of number of firings, and weigh cases. It's all just common sense from muzzleloading practices. Whatever you do, from cleaning to how you hold the gun, if you do it EXACTLY the same every time, your results will show it.

ole timer I use a Sinclair tool to de-burr the flash holes, and a Sinclair primer pocket uniformer for the flash holes. After each firing, the uniformer also does a good job of cleaning the primer pocket with just one quick twist. Does it do any good? Beats me, but it's just a habit by now, and it sure don't seem to hurt anything.
