Can You Shoot 45 Long Colt Ammo in a 454 Casull Gun

1. Any issues with firing .45 colt(long filly) in a .454 casull Super Redhawk?

2. Shooting .45 Colt in a .454 Casull is like firing .38 Specials in a .357 Magnum, in that you accept carbon and lead (if shooting lead bullets) buildup simply backside the chamber throats in the cylinder, due to the shorter case length of the .45 Filly compared to the .454 Casull.

   Shooting standard pressure .45 Colt in a Ruger SRH .454 is like dry firing, but louder . Virtually no felt recoil and near no muzzle rise.

3. Which is no big deal -- just clean later on every shooting session.

4. i ran out of 460mag in my S&West 460 so i shot upwards all the 45 filly i had ,the first few shots i though something was wrong with the ammo but it was just similar a 22 mag.i accept not establish any 454 down here yet and then i deceit say how it does....

5. The potential divergence is that if you lot _don't_ clean thoroughly after shooting .45 Colt in a .454 Casull revolver - at least a Liberty Arms revolver, which is chambered very tightly - you may send a circular loaded to ~60,000 psi through the roof with possible harm to gun and/or shooter. Ruger and Taurus .454C revolvers are presumably less subject area to this, but we accept had threads non too long ago where a .44 Magnum was blown subsequently shooting .44 Russian loads without cleaning.

6. It is indeed possible to raise pressures this style, simply it's more likely that the longer round will decline to chamber when the sleeping room is that fouled.

   Nevertheless, clean after each shooting. Clean agan before going back to the longer instance.

7. I've heard that shooting 45 colt through 454s will result in terrible accuracy due to the rifling. Does anyone know if that's true?

8. No Its Non True

   The diamater of the 454 casull round is slightly smaller than the 45 filly round. Which of course makes for a amend bullet/bore seal and thus actually making the 45 colt round more accurate than the 454 casull.

9. My 625MG in .45 Filly measures just over .480" ID in it'south chambers. My leftover Hornady .454 Casull ammo measures .477" OD, as does my GA Arms .45 Filly ammo - and my homebrews, made using Lee carbide dies - which I as well used to reload my .454'due south with. The simple truth re the .480" maximum OD of the .45 Colt is based on it's initial propellant - black pulverization. Being very muddied, some assart for aforementioned was included.

   I shot thousands of .45 Colts through my 7.5" SRH with no problems, save the embarassment of existence bested, group wise, initially by my 4" .45 Filly 625MG, and later by my 5.5" RH. No, standard SAAMI spec-ed .45 Filly loads - especially cowboy-lite - volition not normally obturate the example to seal off the chambers (Witness the fume trail commonly on the top of the fired example.). Combine that with the low velocity of the .45 Colts (700-850 fps) - and the 'slow' rifling in the .454's butt (Designed for 1,600-two,000 fps), and one can uderstand the poor operation of .45 Colts in my 7.5" SRH. While I could become 1.five" five-shot groups (I allowed a 'flier'...) - with it scoped from sandbags - at 50yd, it wouldn't do better than 4" at 25 yd and six" at l yd, under similar conditions with .45 Colt.

   My .45 Colt-ish loads in .454 cases did better - and had lower SD in muzzle velocity, likewise. I believe this is more a part of the case filling the chamber length to the example rima oris footstep, something that usually doesn't occur in some .45 Colt chambers. I have lost the information taken, simply I remember <3" at 25yd and <five" at 50yd, and mv in the 920-950 fps range, using my usual 250gr LRNFP'due south and 255gr LSWC's. Once more, I recollect the 'slow' rifling didn't help.

   One can't over-emphasize that you lot MUST shoot .454'due south offset, then .45 Colts during a shooting session. Always meticulously clean the chambers earlier going back to .454's. I knew this - but still destroyed a favorite plinker, my 629MG, last February. After shooting hundreds of .44 Russians and Specials, I wanted to ping a 100yd plate i more fourth dimension. I loaded - with some effort - my sole remaining ammo - 300gr LSWC over 6.2gr Titegroup in a .44 Magnum case (~880 fps). I had shot many of these heavy plinkers before. I hit the plate with the fourth shot - and destroyed the revolver with the 5th. The bullet couldn't go out it'due south example due to the lead and carbon buildup at the step - the crimp couldn't release. The resultant pressure spike burst the example, cylinder, and topstrap. A 'double charge' was ruled out, due to the small volume with that long bullet loaded. South&West returned the serviceable part - the barrel - and agreed with me and Hodgdon'due south re the way in which it was destroyed. It was all my fault. Believe me, grime in your chambers from fired short-cased rounds tin be dangerous. Fortunately, I only had to mop up my tears, get another pair of safety glasses (Chipped lens!), and change my britches.

   A peachy manner of cleaning excessive carbon/lead from your SRH's chambers is with a wool mop and metal polish (Flitz/Semichrome) powered by a dull drill motor. This will help with softer-cased .454'southward, as well - like the early on Hornady'south and MagTech's. Fun revolver - I actually miss mine - although my carpal tunnel problems don't!

10. 45 Filly in the 454 Casull

    A couple of points I have non seen mentioned hither. The SAAMI specs for the 45 Colt sleeping room call for fairly large and loose nominal dimensions, a hang over from the days of black powder when you lot had to exit some room for the grime.

    While all the nominal diameters for the 45 Filly and the 454 Casull are identical, the SAAMI specs for the 454 cartridge have tighter tolerances. The SAAMI specs for the 454 chamber call for a tighter nominal size and tighter tolerances. What this boils down to is that there volition exist the occasional 45 Colt cartridge that volition non go into a 454 Casull chamber. I have come across this, particualry with bandage bullet hand loads. Information technology'south the reason they tell you to use 454 dies for your 454 and non 45 Colt dies in the fashion you might use 44 Special dies for 44 Magnum.

    The loose 45 Colt chamber allows the contumely to expand too much then resizing it works it excessively leading to shorter case life and the 45 Colt's reputation for weak brass. Information technology really has nothing to practise with the brass at all, information technology'due south the oversized chamber. The tight chamber is 1 of the 454's secrets to success.

    I picked up a Taurus raging Bull in 45 Filly (Yep, Virginia, information technology's a 45 Colt, not a 454 Casull, and it has six holes.) in part because I thought they might utilize the same 454 reamer on information technology and I'd have tight chambers. No such luck, it has the standard 45 Colt loose chambers.
