Has the Speer 45 colt 250gr GD been downloaded? IT HAS!

[sceva]

I was just looking thru the 2009 Speer catalog and noticed that the 45 Colt 250grain Gold Dot loading is now listed at 750 Fps out of a 5.5" barrel while the previous listings were 900 Fps from a 5.5" bbl.
2009 data: http://www.speer-ammo.com/ballistics/ammo.aspx

I double checked the 2008 catalog and sure enough it was 900fps.

Now, I considered the 250grain at 900fps to be a good compromise between weight and velocity and had made the Speer Gold Dot loading my ammo of choice for personal protection in my 4" 25-5. Now, with a 150 fps drop to 750fps I am rethinking it and may go back to a lighter bullet at higher velocity. IE: either the Blazer ot the at 1000 - 1100 Fps.

Does anyone have any insight or actual test results of this ammo?

No, but I think your thinking is on the right track. 750 fps. is slower than I would be comfortable with.

Here is what Speer Tech Services has to say.

Mr -----
This load (45 Colt 250gr. GDHP)has not changed since 2003 when our
Engineer changed the muzzle velocity to 800 fps from 850 fps.

However, the catalogs have had the velocity listed incorrectly for
awhile. The 'correct' muzzle velocity of this round is 800 fps at the
muzzle. I checked the actual blueprint for the drawing. I will do my
best to get the error corrected. Linda

I asked about barrel length and she says that the barrel length is listed as 7.25" per the cartridge drawing.

I would sure like to see some real world testing in different barrel lengths of this cartridge using recently manufactured ammo.
Lacking any recent independent test results I think that I will go to some other load. I sure hate to give up that 250gr bullet though.

If I can find some I will throw a few over my chrony with my M25-13

If I had the gun and ammo, Sceva, I'd be more than happy to shoot heavily clothed Perma-Gel. 800fps. from a 7 1/2" barrel doesn't impress me either.

Medic15cal,
When you chrony those GD250's be sure to post results. That's my carry load in my 25-13, but don't have access to a chrony.

Sure will!

Anybody want to sell me a box? Hard to find here.
