Anyone use 400 CorBon?

So, Ron, you're also saying that those plain old factory load 135gr. .40 Supers @ 1800 f.p.s. were a pretty good deal? I use 160-165gr. bullets for most of my .40 Super reloading. I don't have any motivation to "push the envelope," so I keep velocities/loads way below max published data.

Ron: Did a Google for ".40 Super" and found that .40 Super operates @ a max of 37,000 lbs/in2.

egzet: How many rounds of .38 Casull and .460 Rowland have you fired? What kind of pistols? Any load data you'd like to share?

Yes and no Rockstar. Pushing a 135g Bullet to 1800FPS is fun and exciting, but you have to remember that the bullet construction is not made for it. You can make or have made custom bullets that would certainly work for hunting; The 135g bullets that are out there are mainly made for the 40 S&W and designed to operate at it's velocities. Beyond that if you are target shooting with the 40 Super, there is no reason the run them that hot and reduce the brass life. I doubt anyone is using a 5-6 inch barrel to shoot 100-150yd targets. Even at 50yds dropping 100FPS off the velocity will not substantially affect the drop for most shooters. Is it cool? Yes. Is it fun? Yes.
The .40 Super does fill a nitch, and I don't see its demise in the near future.

Ron:

I'll defer to your opinion on the bullet design. Please note that I don't load my .40 Supers really hot, and I rarely load 135gr. bullets. .40 Super is just a novelty to me.

It's actually a great caliber, it has the advantage that the 10MM has in that it can be downloaded to 40S&W velocities for light practice, and loaded hotter than the 10MM for increased performance. BTW, where did you get that pressure spec? Out of curiosity, what are you shooting it in and what do you normally load?

I’m still waiting for Ultima to chime in, in response to my comment.

I did a Google search and found this: http://www.jrwhipple.com/guns/40super.html

I'm shooting .40 Super through a G21. I was just today looking at a bag of loaded .40 Supers that I loaded up a couple of years ago. I noticed 13.8gr. of AA#7, and I think that was for 165gr. bullets, but I'll check and make sure about the bullet weight. I also loaded a bunch of 180's, but don't remember what the ones in the bag are. I use small rifle primers and AA#7, exclusively. I've experienced outstanding accuracy, but have only tried 'em out to 100 yds.

One thing I've noticed on this and other boards, some time ago. There are some guys (one in particular) who use software programs, rather than any kind of testing equipment, for their pressure figures. Problem is, they publish their "data" as fact, as if they're actually taking measurements. That just doesn't sit well with me. Software and extrapolation will probably get you in the ballpark, but I'm of the opinion that you need to be more accurate than that when loading on the edge. (which I don't do.)

I got my load data from Tony Rumore.
