I've googled as much data as I can think of. Still didnl't find a ballistics calculator that I can enter variables in.

I am curious what my target loads of 3.5 gr. Bullseye and a 185 gr. semi wadcutter is doing.
I know it's accurate.

Any suggestions or answers?

Thanks.

:)

Prrite that is a great load I use the same load for both 45 ACP and 9MM. Doesn't pound the frame and easy to control.
It's strange that the standard ballistics for factory loads reads:

"The typical . 45 ACP load is a 230-grain bullet fired at 830 fps for about 355 foot-pounds of muzzle energy."

So they're saying our TARGET loads exceed the velocity of factory hardball.

That don't make no sense!

But.... bullet weight....
Gotta delve further into this.

In ...MY... gun, factory hardball ejects cases 12 FEET or so....and...
......this 3.5 Bullseye just drops em at my feet.

The lowest charge I can find is 3.8 grains Bullseye , 185 gr. cast SWC , 5 " bbl = 685 fps
Drop 0.3 grains to 3.5 and you probably have at best 640 to 650 fps ! Typically 0.1 grain Bullseye = 20 fps , although not exactly a unilinear reduction ...it's close
dropping 3 grains = 50 to 60 fps loss ... 685 fps - 50 fps = 635 fps ... maybe 640 or 650 fps tops .

In my experience a 185 gr. bullet at 650 fps isn't going to work a 1911 slide ... you must be shooting a revolver ?

It started out working a Gold Cup just fine. Great, in fact.
Also runs the Govt model just as well. :giggle:

12 # springs of course.

I see , 12# springs explain it ... I shoot an AMT Hardballer , Colt Gold Cup and Colt Commander all with stock 16# springs ... I can't get away with loading them that light . The 16# spring came stock in the Gold Cup which surprised me ... target gun and all ... 12# spring allows some light target loads , may have to give that weight a try ! I enjoy light target loads ... thanks for the infomation !
The AMT Hardballer and Colt Commander get a little hardball ammo run through them now and again so I'll just leave them alone .
Tested a new batch of reloads just this morning.
Functioning great. Very very accurate in both Gold Cup and Govt.
Both series 70. :giggle:

Looking through a 1951 Gun Digest (yeh, I collect em) in the ammo table I saw a 45 ACP 185 gr "Target Master" listed.
No ballistics but I bet it was close to what I am loading.
