I've had a 38 super on my wish list for a long time. No good reason, as long as it's a Colt.
Have you bought your Colt yet?
I was researching the Super when I came across this 'old' thread.
I bought this plain Jane Colt about 7 years ago, like my other Colts, it shot out of the box;
Over time it's become a well used carry at my place and it and a Para in 38 Super have been used on a number of vermin, including a few close calls. This has become one of my favorite calibers to handload for, paying special attention to load for the bullet and not the caliber. As an example, this mild load pushed this 124gr Gold Dot beyond its velocity design;
One of the main reasons I decided to reopen this thread was to help answer questions and define what the Super is capable of doing at reasonable operating pressures, ie, <33,350psi.
We know from water testing and verified by feral goat culling in Australia that the upper velocity limits of the 124gr XTP is in the upper 1300s to low 1400s, perhaps one of the reasons why why Wilson limits its 124gr XTP ammunition to ~1335fps.
We also know that Hornady uses the same load data for 124gr and 125gr XTPs, the latter being the same bullet used for the 357mag. In using the same Hornady data for both bullets, they chronogrphed w/I 4fps of each other. The biggest problem I had with using Hornady data for N105 powder was that the powder weights were too low for reliable slide functioning with the factory Colt recoil springs and a new Para.
This is where things get interesting, enter Sierra #5 manual with their increased N105 powder weights compared to Hornady data. Over a period of time and chronographing different bullet designs, including 125gr Gold Dots and XTPs, not only were factory 357 SIG velocities attained, but one under max load through the Para was pushing the 125gr Gold Dot at ~1435fps.
I had also read the VihtaVuori website data about N105 powder pushing 124grs into the upper 1500s and was very skeptical it could be done because there wasn't enough space in the casing to hold the weight of powder needed for those uber velocities.
VihtaVuori #4 (2006) reduced the max powder weight considerably, a narrower load window than Sierra, although their is a slight overlap, VihtaVuori still packs slightly more powder.
For those who wish to push the Super to very fast MVs while keeping operating pressures under 33,350psi, I strongly suggest VihtaVuori #4 and N105. N105 is a single perforated neutral powder. Most handgun powders we use to handload are classified as degressive, meaning they have a high pressure spike, Pmax, that drops off sharply as the bullet travels down the bore. N105 as a neutral powder, has a lower Pmax, yet it retains a higher bore pressure than degressive powders. Total pressure under the pressure curve is basically the same. The closest analogy I can think of is the very high operating pressures (40,000+psi?) of the 9x23mm to push 125grs to ~1450fps and under max 125gr/N105 knocking on 1500fps.
Here's a recovered 125gr XTP that had an under max loading that chronographed at 1491fps;
A second chrono test showed 1486fps through the Colt, low extreme spreads with N105. Loaded this way, the Super is literally a 357mag in a 1911, but with unmatched split times.
Last winter I had a situation with a coyote. I was out with my German Shepherd off leash when we noticed a coyote at distance going from right to left, it noticed us, changed direction and trotted toward us. The GSD is trained to sit when I draw and he did so as the coyote approached.
Different coyote, pic is zoomed in at ~60 yards. The coyote that was advancing was guesstimated to be at ~75-80 yards, far enough away that its ears were well within the width of my rear sight. Fixed sights being what they are on the Colt, the 125gr XTP tore into the 'yote's shoulder and the distance turned out to be 95 yards, on a moving target.
No longer made by Para, but a nice carry and BBQ piece ;
Can't say about others, but I find the Super to be a very versatile carry, great for the Southwest environment when a flat shooting and accurate caliber is a requirement is needed.
