.45ACP Observation - Flash Holes
 
Interesting observation the flash holes on Federal cases was larger than
the Winchester cases. I noticed this today seating new primers. I used
wire gauge drill as gauge pins.

Fed was #39 drill, 0.099"
Win was #47 drill, 0.078"

Where the federal cases small primers? It prolly has a larger flash hole due to that.

These differences are not uncommon.

Unless you're a world class competitor, they won't make muchg difference in your shooting

It was only an observation.

Several years ago the Winchester white box .45 ACP had noticably larger than average flash holes. It caused much consternation amongst reloaders. It was found to have little or no effect on reloaded ammo.

astute, and accurately described using the numbered drill size as reference.

I can see visible differences when running batches of mixed cases.

Yep, I throw measured charges into mixed cases. LRN with a light powder charge.

Thanks, I have never seen a difference with flash hole size, I do not
shoot bench rest either. The difference was very noticable.

I cast my own LRN (Lee 6 caqvity die, 230 grain) Lee P/N TL452-230-2R.
Tumble lube them
RCBS carbide dies
Mixed cases
Remington or Winchester Large Pistol Primers
4.0 grains of Hodgdon Clays

I have a stock Colt Series 80 1911, nothing special except reliable. The
above load is more accurate load I have yet to find for it.

I have a new source of once fired brass, mixed brass from a police range,
losta .40 S&W, and .223 Rem. and other misc. cases, finally saw my first
.45 ACP small primer cases, 5 cases total. Gonna save them for now.
