Lyman Mould Questions

I am brand new to casting.  A good friend gave me all of his late father in law's casting equipment.  Included in this prize was a collection of 19 different moulds.  He had placed labels on the end of each mould box to describe the mould.  He described 452460 as a 200 gr SWC for the 45 ACP, no problem this matches what I see in the catalogs.  His label on 452490 describes it as a 230 gr SWC for the 45 ACP; this is not what I see in the catalogs.

1)  These mould are old.  Is it possible Lyman has different mould carrying the same number.

2)  I have loaded 255 gr commercial cast SWCs (sized .452) for my RBH and Vauqero's with great results.  What do you experts think about using the above 200 and/or 230 gr SWCs in my 45 Colt revolvers?

Thanks,

Kajan on the Bayou

  1. The 452490 is a 230 grain SWC that uses a gas check, no longer made.

  2. Either bullet would work just fine, except that point of impact will be lower on the target than 255's.

If you want to sell or trade any of the moulds, please PM me and I will respond.

Anyone with experience with the 452460? Buying one here from Ikydvl.

Well, I've shot tens of thousands of then in Bullseye NRA matches and practices. They feed well and are as accurate as anything else I've used. I also use it as a plinking load in a S&W 625 in 45 AR with 4.0 grains of Bullseye. Ric

Thanks Ric, that's encouraging. Ikydvl says my mold is on the way. No idea if it's a single or what. When you cast your 452460s what is your alloy? I'm thinking of using 50/50 ww/Pb.

If I am making bullets for a semi-auto, I wouldn't use anything softer than modern WW's. But that is only for feeding up the ramp and into the chamber, as soft alloys tend to grap the metal ramp and not slide. For my revolvers, I use range scrap and left overs from culled bullets and end of lots of other alloys and it is soft. I just make sure that it is at least as big as the throat of the cylinder. HTH, Ric

Kajan; 200 gr bullets are not apt to shoot to the sights on fixed sighted guns regulated for 255 gr bullets.

However, in my Ruger SS Black Hawk Bisley .45 Colt/.45 ACP convertible, there is plenty of sight adjustment to sight in the gun for either bullet (and in both cylinders).

Fixed sighted guns don't have that luxury.

The 200 gr SWC Lyman is a good bullet.

Got 'er runnin'. The 452460 looks like the ticket to me. Cast up a pile with ww+1%. Tumble lubed with LLA/JPW/mineral spirits. Then >452 Lee push thru sizer and another coat of tl. I had to seat them a bit short of Lyman's reccomendation, (1.161"), mine are 1.15” or they won't chamber in either one of my 1911A1s. One is a Charles Daly that is actually a nice gun, the other is a ugly beast I built, 10 .lb trigger and issue sights. Off to the range soon. Oh, I'm trying 4756 because I have a lot, it burns similar to Unique, and also some Bullseye for comparison. (That trigger is on my to do list).

i have a lyman mold for a 220grain semi-wadcutter, icannot use it in a .357 magnum, as the case bulges too much and will not chamber in a revolver. which cartridge is this bullet to be used in ?

RE: 452460

I have tried it, lubed but unsized, in a .455 Webley with miserable results. I believe it is too short to properly align between the chamber and the forcing cone of the barrel. And yes, it does take the rifling.

With a TC Contender .45 Colt, sized .452, in a 10” barrel it gives superb accuracy--3 rnd. cloverleafs at 25 yds--and mild recoil with target type loads.

February 2002 issue, # 215 of Handloader has some excellent info on reloading for the 455 Webley

We looked for a long time for the  long discontinued Ideal (Lyman) mould # 457195 and went on to try the RCBS- 45-265-RN-HB mold http://www.midwayusa.com/viewProduct/?productNumber=195619>http://www.midwayusa.com/viewProduct/?productNumber=195619

Use a hotplate to keep the mold warm, use softer lead in keeping with the design at least 2% tin in your mix to fill out - .456 sized for my friends revolver.

Artful,

I have the Handloader article you reference. I usually shoot the RCBS bullet you mention because it duplicates the weight and profile of the Brits' .455 load. Lyman's 454424 (original Keith style fat SWC for older .45 Colt barrels) shoots quite well in my Mark VI, too.

With either the RCBS bullet or the 454424 bullet, my Mark VI is capable of consistently hitting man-sized targets, i.e., B-27, at 100 yards--the longest distance I have tried. Out to 50 yards offhand, I'd put it up against any comer for combat accuracy.
