45 Colt 250 gr. Speer Gold Dot “Deep Curl” Bullets

[Slip Shooter]

Do any of you have experience with this Gold Dot bullet? What about velocities and pressure signs?

I want to purchase these bullets to use in my 45 Colt clones as defense loads. The Speer #14 manual is the only source I’ve found and it seems to me that the powders they recommend are all on the slower side.

I have never loaded jacketed bullets in the 45 Colt, only 250 to 260 grain lead. My experience with most of the powders listed by Speer for this bullet give large velocity variations of 50 to 70 fps. I would like much better performance with this bullet. Will this jacketed bullet’s increased drag help with better ignition and extreme spread?

I am looking for a velocity of about 860 fps.

Has anyone out there used and chronographed these bullets in a 5.5 inch revolver?

I am also open to all powder suggestions.

Several reviewers have written well of the bullets performance at 45 Colt velocities on the Midway site.

So what exactly is wrong with Speer #14's data??? Unique is in there and that's what I would use in that velocity range, only I'd go up to 9.0gr.

I tried them in a 7.5" using unique, but didn't chrono them. Performance on paper was great though. Since it's a plated bullet it expands well at normal 45 colt velocities.

If I were looking for that velocity, with that bullet, in 45 colt, I would use Power Pistol. Thats mainly because it will make that velocity easy within SAAMI spec, and I keep it on hand anyway.

Deep Curl are hunting bullets. Unless you're very rural, a shallower-penetrating bullet would be a better choice.
