45acp +p & 45 super

[YotaAtieToo]

The .460 is cool because you can shoot .44special, .44mag, 460 S&W and .454 Casull. They're fun to hand off with a mixed cylinder.

I do remember that, and that's exactly why I wanted it. I'll buy a box of 454 or 460, but if I'm getting familiar with it, I'm. Probably shooting cheap 44s

Alrighty finally got around to playing with some .45 super type loadings

all I got is 230gr jacketed
I cut apart some wolf steel .45 boxer cases, some blazer SPP brass and some federal SPP brass and all of them look to have the same case web thickness/profile though the wolf steel case (large pistol primer) has a thinner head than both of the SPP flavors of brass I had, so I guess the wolf stuff is out and the small pistol .45 is in

I hadn't read too much into it, just started playing around with blue dot because I've got a lot of faster powders and a tiny bit of ancient herc 2400
people say that blue dot doesn't like high pressures, which wierds me out being that it is all I've ever used it for, heavy 357 loads and 9x25 dillon mostly. Makes a nice bright muzzle flash and burns real clean when you get it loaded up hot enough.

Anyways, started with the .45acp max load of 10gr of blue dot and worked it up in half grain increments to 11.5 before I thought to poke around some more and found that bit about multiple people saying not to use blue dot specifically. People seem to use powders that are both faster and slower with no real comment...
So, what's up with that?

the 11.5 was starting to bark/burn good and finally starting to get the primers to look like a light rifle loading...
Torn on trying the 2400 or going out and trying to find some longshot or aa#7
Chrono wasn't happy with running indoors, must need better light.

Blue dot can be a bit unpredictable. It's position sensitive and excess empty space sensitive and both cause pressure spikes. Not unlike H110, which is dangerous if you load to less than recommended loads. There was also a recall on blue dot a few years back after several kabooms. Its overall considered to do some unpredictable and spooky things, especially near the edges of the load. Most reloaders avoid it for this reason

I used mostly longshot in my 460 rowland loads with good power and consistency. It's a bit louder than most powders at the same velocity but when you are getting into supers that matters less.

Good to know, and rather disappointing as it's an old friend.
I'm just wierded out by it because there are guys using 800-x and power pistol which are way up the burn rate chart from blue dot. Must be that blue dot is just an ancient powder with old burn rate retarders that don't stand up as well as newer ones. They can't just 'fix it' as then it'd be a different powder. Shits of it is that there still ain't shit for powder available lol

powder valley had 4lb cans of longshot so I grabbed one, wouldn't let me get two. :\
