Does anyone have any good loads for .45ACP specifically for a bolt action carbine. I’m trying to push 230 and 200 PC’d cast fast but I am having limited luck finding data, and of course powder variety is often limited. I’m using 5.3 grains of Titegroup but the 230 seems, anemic at best. I loaded some 160gr RN with 6.7 grains of titegroup, that load is fast and hot. Titegroup is so fast though that the extra barrel length isn’t seeming to wring much out of it.
 
Use .45+p or Super data. Be sure to use brass in good condition or you may have issues. The strength of the case is much greater than it is given credit for. Titegroup is way too fast to get maximum velocity. HS-6 or Longshot are great powder for fast .45.
 
If you're shooting this in a Delisle-clone, look at the original pressures a No.1 or No.4 receiver can handle. That will help you decide on .45ACP loads.

I'd think that any .45ACP fired in a Thompson or an M3 SMG would be the baseline for pressure, MV and bullet weight. And, the longer Delisle barrel would be slightly faster.
 
I tried the Plus P loads in my No4 conversion and even with maximum loads there weren't any signs of high pressure.

I used standard Large Rifle primers for my loads.

I've been looking at 460 Rowland loads and have gone so far as to put a max charge of powder into a 45acp case to see if there is enough room to seat the bullet.

Case capacity isn't an issue.

Of course, I won't start with that much powder.

These latest conversion kits aren't trying to mirror DeLisle Carbine results. Noise isn't a factor. The more than three times barrel length of the Carbine over most pistols should give some usable velocities, even with the heaviest bullets.

If you're worried about getting the cartridges mixed up with your handgun loads, either don't do it or make darn sure everything is properly marked.

I do three things to make sure my loads don't get mixed.

I use a bright RED label on the loaded cartridge containers, use RED FELT PEN to color the base of the cases and use RED powder coated bullets.

If you're shooting one of the PCC, semi auto carbines, just stick with regular 45acp loads at 800-900fps

Good Luck.
 
Under 30,000 psi regular ACP brass of decent manufacture seems to do just fine. I use Super and Rowland brass myself just to keep things organized. 49,000 PSI will be a bit ridiculous and I foresee many issues if you go that high. 40,000 is the Rowland max and is pretty incredible from a pistol, it will be plenty.
 
I dont have data only a value.

Shooting Atomic 185 gr+P at 1225 fps out of my H&K Mark 23, over the Labradar my 8 inch insert ( out of a 12 gauge ) of 45 ACP run them a tad below 1450 fps.
It got some zip to it. JP.

Yes indeed. 1450. That's pretty darn close your average factory 240 jacketed 44 Mag out of 16 inch Trapper barrel. You bullet only a bit lighter.
 
I sped a 225gr PC to 1200 f/s with 6.6 gr of unique in the JR carbine and like the results. I will be trying these and even hotter ones in my Enfield conversion as well and hope to see what It can do. I will be following this thread too

The action may handle the pressure. What about the brass?

The brass should be OK. I'm going to work up the load increments and check the cases along the way, before going to the next bump.

Being a straight wall case, of limited capacity, all should be well.

Good idea.

I was even thinking about making some cases out of 308win.

I have a bunch of cases set aside for the same purpose. I doubt I will get to it any time soon since I don't have a lathe but sooner or later...

A hacksaw, file and trim die are all you need

The case necks will likely be to thick but it's worth a try.

I was planning on turning the inside diameter to the depth I want to seat the bullet. It's doable on a drill press, with a cross feed vice. This will allow use of standard 45acp dies, just need to be mindfull of how deep the expander is set.

I've done this with other cases, to utilize stronger brass, The case needs to be chucked up in the Drill Press and the insider cutter is held by the cross feed vice.

Where there's a will, there's a way.
