For loading .45acp for a revolver. Any load data or prior experience. Thanks

Oh loading for a Thunder Ranch

Don't go low with jacketed bullets, use cast.

What bullet weight?

Any lead bullet over 3.3gr of Trail Boss will send it at about 650fps. The 180gr bullets will have the least pressure resulting in even less recoil.

I bet it'll feel like a 22.

And like Wisky said, don't try it with jacketed bullets. You might get a squib.

As long as the bullet leaves the bbl, your good. BUT, this is where a lot of guys get KBs, if the charge is so low that recoil is so low that you can't really tell if it fired or not, it's trouble. I am quite happy w/ a 200gr bullet moving 750fps as my light load in my 625. Certainly do NOT want to be shooting jacketed below that.

You reach a point where the pressure is so low that the case doesn't expand and they get filthy too. Deep seating, fast powders, help mitigate this.

I don't have any experience loading 45ACP, but I would look at some of the old Lyman data for the lightest 45 auto rim or even some of the lesser 45 revolver calibers like Schoefield.

Low vel 45AR loads are interchangeable as well. I just am not comfortable going much below 700fps, I want enough report & recoil so if shooting fast, I know I don't have a squib. A 200gr bullet @ 700fps feels like a 38 WC load in a revolver.

So basically to go mouse fart it has to be Lead. What's some of your lighter loads with Berrys 230gr with WST. About 4gr or has anyone gone lower???

Like all reloading start where you know it works and work up/down from there. Each firearm can and usually will be different.
Hope you get it where you want it. :supergrin:

I have found that with my 625s or 25-2 that when you get the Berrys 230s below about 650 fps or the 185 HBRN below 730-750 accuracy really drops off.

I am using Hodgon Clays or Vhit N310, Federal primers and Winchester Match (WCC Match) brass with an OAL of 1.245.

I've gone down to 4.2gr w/ a 230grLRN for about 725fps. I would think a plated would be right around 700fps.:dunno:

One sure method would be to perform a reverse load workup. Start dropping your charges until you finally stick one, then bump the charge up .2gr as a safety factor. :supergrin: (obviously, carry your squib rod with you to the range).

There is a lengthy section in the Speer Manual about the hazards of making loads that are below laboratory minimums recommended by manufacturers of powder and bullets.

Pressure varies at very low densities. Cases do not expand to seal chambers and actions. Primers back out and jamb revolvers. And, the risk of stuck bullets is increased.

I've done some very light loading for action shooting where power factor is not an issue. In my experience, loads that are below recommended minimums will eventually, under certain conditions, cause problems. Usually, for me, issues of primers backing out was the problem, but erratic ignition also surfaced on cold mornings.

Again, read the speer discussion in their manual.

I agree with these, and all of the other cautions posted in this thread.

180 grain lead over 4gr trail boss is pretty anemic load. the bullet does go thru the paper :O) I think I had to manually cycle the 1911 though...
