    Lyman 452423

    This one was around for quite a while, but is now out of production. I had one for a time and used it in the 45 ACP in an AMT Hardballer. It shot high due to the increased weight which was around 245 grains. I struggled with the sight settings for quite a while and finally got rid of the mold and the hardballer. Its a good design but I think that it would be a better choice for a revolver in 45 LC. LLS

    This is a good write up about the 452423

    There was also a group buy for this boolit a while ago so there should be some recipes available.

    I have a double cavity in this mold, Mine weighs around 250 grs.,out of my alloy. It is a shorter design with a larger meplat than the other 250 swc offered by Lyman. It's a good bullet, but as said, can shoot to different point of aim than the 230 gr. slugs. This is not an issue with me since all my 1911's have adjustable sights. It can be finicky to get to feed reliably in some . I have shot it in my 625 revolvers, and Ruger .45 Blackhawks, too where it is a good performer, but have generally gone to 200gr. bullets in the 625's.

    This was the first 45 caliber mold I ever purchased, and my most used one. When I ouught a Ruger 45 convertible model about 30 years ago the big bullet for this caliber could not be found. After experimenting, 9 grains of Unique with a standard large pistol primer in 45 Colt is dandy. Mine weigh in at about 235 grains.

    Wasn't this design intended originally for the 45 Auto Rim revolvers?

    Yes, this was Elmer's design for the 1917 .45 ACP revolvers, either with the normal
    rimless brass or with the rimmed brass.
    Works very well in mine, once I got one large enough for my .454 throats and then
    loaded it hot enough to hit near the sights. Light loads hit well left, but as the loads
    get hotter they move right towards the POA.

    Yeah, I've approached some of Elmer's loads with that bullet for the M1917. They were warm and I didn't ever get to his level with Unique but they will make a great man stopper.

    I have found from shooting them from ACP cases in a .45 Ruger convertible that they tend to wander a bit at 100 yards. Too much to be useful for plinking at that range but again, we're talking pistol here and they're good at 50 yards./beagle

    For my 25-2 I load the 454423 GB over 7 grains of Unique and enjoy the results. EK went to 7.5 but I have not.

    In the 45 long Colt, I have shot this boolit over a case full of black powder and had a lot of fun with good results. I enjoy shooting black powder and find clean up is about the same for the firearms but a bit more for the cartridges.

    Does anyone knw if Mr Graff wrote a similar article about 454424?

    I. too, went up as far as 7.0 gr Unique with this boolit in a 1937 S&W (Brazilian contract
    version of the 1917), but never went all the way to Elmer's 7.5 gr load. The interesting
    thing is that the 6 gr loads shot about (IIRC) 4-5" left and a bit low. By the time I got
    up to 7.0 gr it was level with POA and about 1" left of center. The POI moved ever closer
    to the POA as the loads increased.

    I lusted after one of these moulds for my 625's (.45 ACP's). However, I "settled" on the NOE clone of the Lyman 454424. It weighs 250 grs out of WW's+2% tin and can be safely driven to 900+fps in my 5" 625 with 7.0 grs of Unique. It makes a powerful (as powerful as the original .45 Colt black powder round with a much better shaped bullet) and quite accurate load for deer, hogs, and black bear at reasonable range. Here's some cartridges (.45 Auto Rim) with those bullets:

    I have a single cavity Lyman mould for 452423. Results in a Colt M1917 and a S&W 22-4 have been excellent. I was so pleased that I filed the 22-4's front site so points of aim and impact coincide.

    I wish I had been a member for the group buy. The single cavity mould is too slow. I keep watching for another group buy, but it may be awhile.

    Doby45;

    I have a Lee Factory Crimp die for the .45 ACP. It comes with a taper crimp insert. I called Lee and they have an auxillary insert+spacer for a roll crimp. It requres replacing (temporarily) the taper crimp insert with the roll crimp insert and spacer. Both crimps work as designed.

    Ben;
    They ARE!! The NOE mould is a five cavity aluminum mould of the correct design AND size. It is excellent in every way.
