Anyone ever shoot Remington-UMC or Winchester White Box .45 auto over a chronograph?

What barrel length?

I've got a chrony but just thought of it today...I wonder how consistent the velocities are.
 
OK, so they really are full (standard) velocity loads.

Interesting. I thought they might have been a little under-loaded...for some reason.
 
Some brands may in fact be on the softer side, but WWB in just about any caliber is very "standard" it seems.
It's not particularly hot, accuracy seems to be pretty good in every gun and caliber I've used.
Their 44mag load is actually very respectable, but that's another topic.
 
A friend has an inexpensive Taurus .357 that is amazingly accurate with WWB 110 gr .357. Too bad we did not chronograph it, but it was more accurate than target wadcutters.
 
Yankee,

Here's what I have for the Remington UMC 230gr rounds:

Remington UMC, 230gr
Government, 5.0 in barrel
835 fps
SD 15 ft/sec
 
Even if you have one or more data points from others, I would be very surprised if plinking/range ammo like WWB or UMC is actually 100% consistent from lot to lot.

The only way to really have any idea what it is doing in your gun is to chrono that specific batch out of your specific gun.
 
For me WWB averaged 821 from a 4" S&W 625 and 960 from a Camp Carbine at the same range session.
 
when it comes to bulk centerfire fmj ammo, this in regards to not just the .45, the barrel length makes a huge difference. Just an inch can add or subtract 100 fps from the velocity. Compare that with self defense hp's and the fps doesn't change much maybe an extra 30 fps per inch.

the extreme spreads can be extreme, but that's to be expected with bargain price ammo. The longer the barrel u use, the more consistent your velocities will be as the powder has more time to burn.
 
Interesting; I'll have to chrony my own when I get a chance...which unfortunately won't be for a while.

For some reason, being plinking/range fodder I would have expected them to be a little "short", like 750-800 from a 5" barrel.

Don't know why I thought that, really.
 
I don't know if the Winchester "brown box" is any different than the white box which I haven't shot any of recently.
But the "brown box" does shoot very well (acouple different lots) through my 625 4"er.
I don't have any data points as for velocity however.

I've tested WWB in many different calibers, and never found them to be sub par from a velocity perspective. An earlier reference was made to the WWB .44 Magnum, and many people choose it to deer hunt with in carbine length rifles.
 
As far as quality goes I have never seen any difference between Winchester White Box and Remington UMC, as far as dud rounds or defective cases or anything, and I've shot a lot of both, especially in 9 x 19.

I do actually prefer the UMC for packaging, especially since it seems like some of the Winchester rounds get glue on them from the box flaps ha ha.
 
The original 1910 45 ACP load, used in the tests of the M1911 and the Savage pistol, had a specified velocity of 800 fps with a 230 FMJ. The load was five grains of Bullseye, which is still an excellent hardball load.

These boxes show what the velocities were for the Army match ammunition in the early 60's.

I once chrono'd about 5 different makes of .45 and WWB was good and consistent while UMC was horrible, a different speed everytime. So much variance I wouldn't buy it again but WWB is good stuff.
