.45 APC Reloading --- Flash Holes
Hi All I have been a bystander for the last few months and really like what I see on this site and have learned alot just by reading but now I have a question or two that I have not ran across before maybe someone can shed some light. Yesterday I was working on some 45 brass ( that I picked up on a range ) before reloading and noted that I had some Win. brass that someone had enlarged the primer flash holes ( to about .130 ) I have heard of comp./target shooters doing this for benchrest stuff. My question is 1. does it realy make that much diff. on a 45 or was someone just playing and 2. How would it cahnge the losd as far as pressure and volocity goes. ?? THANKS FOR YOUR COMMENTS AND OPINIONS

There are a couple companies that are manufacturing a couple different caliber handgun ammo with different size flash holes.
If you don't care where you are going, you can't get lost.0 -
I load 357 magnums for indoor usage (in a pistol)using rubber and plastic projectiles that you can buy in most gunshops .The cases are loaded with NO powder at all and are fired by primer only . Approx. speed of projectile is about 500fps without powder .The problem is if the flashhole is not enlarged ,the amount of pressure generated causes the primer to pop the primer back a little .This causes the cylinder on a revolver to lock ,thus not rotating .Once the flashhole is drilled ,normal cylinder rotation is achieved .Drilling out the flashhole is recommended by the rubber projectile manufacturers to reduce the pressure and prevent this lockup .This would only be a problem with revolvers .I would imagine with an auto that you would have to cycle each bullet separately as the pressure would be insufficient to operate the slide .I have permanently marked all my cases that I have drilled out so as to make sure I NEVER use them for my normal reloads . Not sure whether safe or not for normal loads but I am not going to risk blowing my gun apart. JMHO.

Above is incorrect.
The larger Flasholes are for the "New Clean Leadfree" ammo.
These are made to be shot in indoor ranges.
I load them the same and can see no practical differnce or chrono changes in 45 ACP

cpermd,
I am not sure if you are referring to me when you say the above is incorrect ,but if it is here is my reply ; I am not incorrect .I have searched out my original documentation for X Ring primer powered rubber bullets (made in the USA) and can email you the exact same information that was contained in my reply .These rubber projectiles were made in .38 / .357 .44 and.45 calibre.
Whilst your information may be correct also (I personally do not know about "New Clean Leadfree" ammo.) it would be appreciated if you did not discount my information as being incorrect .

Just thought I'd chunk this in about the .45 brass. I reloaded lots and lots of .45acp, and some have had bigger flash holes, but I didn't change my load or seperate them, and haven't had any problems. I just treat them like the rest of the brass.
Hope this helps.
If I'm wrong please correct me, I won't be offended.

This was brought up some time ago here; and there was some concern at the time, but this has yet been proven to be a problem.

Sorry Aussie
Not yours.
Speer and X Ring make or made what you described.
I shot one through the sheetrock in my house about 30 yrs ago.
Primer only,I was aiming at a big rat.

Yep, seen 'em too; first in Winchester, then when I started using Speer Lawman 45ACP. As with the earlier posters, it doesn't seem to adversly affect my handloads any. Separate 'em out if you want & keep track of your results to see if it's worth the time & effort. 0 -
Thanks all, Planned to separate and try them but just wanted to get some other input as to any diff. in loads. I shoot a light target load so I will prob. use extra care and experiment. THANKS AGAIN

I definitely would NOT use the cases with .125"diameter
flash holes for full power loaded ammunition. This is the size to drill cases using primer fired rubber bullets so primers dont back out and prevent revolver cylinders from turning.0
