Colorado Coffinmaker Posted January 19, 2022 Share Posted January 19, 2022 First a CAVEAT: I've been shooting 45 Cowboy Special since it's inception. Using 45 ACP dies will work but is not optimal. An ACP resize will impart a slight taper on the brass and contribute to Blow-By. Use a standard 45 Colt Resize. 45 ACP bullet seater will work a treat. 45 ACP crimp die, not so bueno. You need a nice roll crimp. I like a Redding 45 Auto Rim crimp die. For smokeless, I shot 4.0Gr TightGroup I now shoot 15Gr 3F APP. I like 165Gr RNFP from Scarlett, Missouri Bullet, or Badman. My all time favorite is the 130Gr BARNSTORMER. See Shootin Fox for the Barnstormer. Barnstormer's ROCK!!! Link to comment Share on other sites More sharing options...
Slapshot Posted January 20, 2022 Share Posted January 20, 2022 I just checked and I get .002 difference from sizing my brass with the 45 acp die as opposed to using the 45 colt die. I use the Lee 160 RNFP mold and PC my bullets and size to .452. Link to comment Share on other sites More sharing options...

Every time the COLT SAA pressure limit comes up the 14,000 psi number is thrown about. SAMMI set that number on an old cast iron frame gun. The gun is far stronger than that number. I will say no more. Link to comment Share on other sites More sharing options...
Springfield Slim SASS #24733 Posted January 20, 2022 Share Posted January 20, 2022 I'm with CC on this one. I don't even run the sizer all the way down as my wife's rifle has a chamber cut on the large side. And I greatly prefer a roll crimp, as I do NOT want any chance of the bullet being pushed back into the case in the rifle. 45 acp use a taper crimp as the shell headspaces on the front of the brass, not the rim, so it has no real purpose on a C45S.

Woodfox 3.6 gr of Trail Boss behind one of Scarlett's RNFP 160s. I prefer a Federal Magnum Large Pistol Primer. For two reasons. First, I think it helps the TB burn better in all weather conditions. TB can be a bit funky especially here in Michigan in cold weather. Second, I believe that the Magnum primer has enough umph to push that 160 gr bullet out of the barrel if the round is a squib.

The loading data is based upon that limit, and I find 45 Colt challenging to shoot fast and accurately even within that range. In our context I think we care about lighter rather than heavier.

Twelve Bore Posted January 20, 2022 Share Posted January 20, 2022 If you are using 45 cs in your rifle then you are using the Smith Shop carrier correct? With the lighter bullets mention are you crimping in the crimp groove? Link to comment Share on other sites More sharing options...
Colorado Coffinmaker Posted January 20, 2022 Share Posted January 20, 2022 Twelve Bore Yes. I shoot C45S in three different Toggle Link Rifles. ALL use The Smith Shop carrier block. YES!! I crimp in the crimp groove. As an additional FYI, the rifles run the 165Gr bullets like wet grain through a goose. Barnstormers DO NOT play well with a rifle. The Barnstormer is gang busters inna handgun though Link to comment Share on other sites More sharing options...

Cast iron has little tensile strength, and would blow up with the forces in even a handgun. And just about all SAA failures from over-pressure blow a cylinder chamber out. A few also blow off the top strap. So weak cylinders (at the bolt cuts) are as important as weak frames. The industry standards committee is SAAMI . Pressure capabilities also depend upon whether we are talking about Uberti or Pietta or Ruger clones or a Colt SAA. Because their are SO many different .45 Colt handguns around, the committee set pressures that would be safe in all smokeless powder designs. As said earlier, if you know the pressure limits for your gun are higher, AND you really want all that recoil, go for it. Otherwise the established max pressure limits for .45 Colt are plenty high enough for general use. good luck, GJ Link to comment Share on other sites More sharing options...

Colorado Coffinmaker Posted January 20, 2022 Share Posted January 20, 2022 OOPS! Again The Bullet I ran this past season for the Rifles is 180Gr. Also from Scarlett, Missouri and Badman.

Now , Colts made of modern steels will handle 14,000 plus. I say no more. Best Wishes Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted January 20, 2022 Share Posted January 20, 2022 SAAMI was SET UP solely SOLELY to set functional specifications, including pressure SAFETY STANDARDS, for the sporting arms industry back in the late 1920s. I don't see that they are protecting the SAAMI trade group with their standards, but they are protecting the public from the uncertainty of knowing if any given batch of ammunition would function safely in any particular gun that was manufactured. And thus protecting the gun manufacturers from unwarranted lawsuits that actually were caused by bad ammo. And the ammo makers from suits rooted in poorly designed firearms. Up to that point, there was such a severe problem with ammo and gun incompatibility that Congress was threatening to take action by regulation, due to public outcry. The firearms industry wisely stepped up and said "We'll voluntarily set one standard that we will all agree to follow." In my understanding, they did the right thing both legally (for safety of public) and for maintaining their profits. I do not see this as covering one's (company) butt, but instead wisely deciding to do the right thing for the whole industry. Similar things are done in the liquid fuels business to ensure you get the octane number of gasoline products that you purchase, and that the diesel oil will pump and burn properly in any truck or in any home heating system that you have chosen to run. good luck, GJ Link to comment Share on other sites More sharing options...

Garrison Joe, SASS #60708 Posted January 21, 2022 Share Posted January 21, 2022 The MAP pressures of the standards make a minimum pressure level to which a gun has to be designed. Yes, almost all the guns now well exceed that minimum pressure level to keep the gun safe, especially Ruger and Freedom Arms. The standards have worked for that intended purpose. The standards have not been "cooked" to prevent higher pressure non-commercial loading. IF you control the use of the resulting ammo and understand what you are doing, feel free. good luck, GJ Link to comment Share on other sites More sharing options...
PanioloPete Posted January 30, 2022 Author Share Posted January 30, 2022 On 1/18/2022 at 11:26 AM, Springfield Slim SASS #24733 said: All this talk of freebore always makes me laugh. For years people who wanted accurate target guns loaded 38 special brass in a .357 gun, and used a big flat ended bullet seated flush with the end of the brass, that would contribute nothing to centering itself in the forcing cone of a barrel. And it worked fine. And here we worry about being able to hit an 18" plate at 20 feet or less. True enough! I started thinking about that when I was reorganizing my bullet and case storage. Heck, I’ve been shooting .38 Specials outta my .357 revolvers for years without a problem or second thought! Link to comment Share on other sites More sharing options...

Roscoe Regulator Posted February 1, 2022 Share Posted February 1, 2022 4 hours ago, Judge Gardner said: 3.4 GR. of titigroup and a 160 GR Rim Rock bullet. It makes power factor. If you know the power factor is good, then what is the velocity part of the calculation? 400 is minimum, so a min PF of 60 would only be 375 fps. Your load is well below any comparably sized 45 ACP for 160 gr (Lyman Lead manual, #2 alloy); 5.3 gr TG; 922 fps; 65% max pressure rating for 45 ACP.
