I need informed opinions on which load data to use for loading some 45 ACP 200 LSWC. The bullets I have were made by Dardascastbullets.com, and they are .452 with reported Brinell hardness of 18-20. I think they use Magma molds, and a link to the exact shape of the bullet is here: 200 SWC
I am confused. On page 382 of the Lyman manual, 49th edition, #452460 lists 3.5 to 5.6 for Bullseye, and bullet #452630 lists 4.9 to 6.0 for Bullseye. The data on the second one is similar to Hornady's data for their 200 gr SWC (4.6 to 6.3) The manual lists a seating depth of 1.235 or so for these. Does that sound about right? Then, Alliant's website lists a max of 4.6 of Bullseye with the Speer 200 LSWC.
Thanks!

The way to what is correct for you is two fold.Establish the OAL by the best place to crimp.I start at the middle of the forward band and taper crimp.You might need to go farther forward,depending on your chamber.After that is determined start with the average of the several starting loads and work up to the point that your gun cycles reliably.If you have access to a chrony you might want to work up to or stop at the published top velocities.

I was hoping to get a sense of safety. I loaded up some at 5.2 gr of Bullseye based on the Lyman and Hornady data, which suggest that that would be a bit above starting loads of 4.6 or 4.9. Most people's pet loads are listed around 4.4 or so of Bullseye, but I was looking for something a little stronger to simulate a factory round, and not for a target load.
I do need a chronograph, but for now I want to make some safe loads for fun.

What Wheez said and by the data you posted, I would start about 5.0-5.2 and work up to reliably cycling. and then fine tune for accuracy at your shooting distance.

Assuming that your pistol is equipped with a factory recoil spring that still measures at least 6". Pay attention to how far it throws empty brass from factory loads. It should be around 6 feet. Make sure your reloads do not exceed this distance. I still check this even though I have a chronograph. PS. Make sure you replace your recoil spring when it gets down to about 6". Most new recoil springs are about 6 1/2". Hot loads will cause serious damage to a 1911, so tread cautiously. As far as adjusting oal is concerned. Remove your barrel and adjust overall length so that a cartridge inserted into the chamber falls even with the rear of the barrel hood or just slightly below. ( maybe .005 to not over .010 ) This should produce the best accuracy for you from that particular load.

If I'd seen this sooner, I'd have hollered. I shoot the #452460 with W231, and 6.0 grains is the absolute max I'd ever consider using in a 1911. A far more reasonable max would be 5.5 grains. Bullseye is a lot faster than W231, and IMHO, 6.0 grains of Bullseye is way too hot.

Looking at the 2 bullet styles I think the answer to the different powder charges is because the 452460 goes down farther into the case than the 452630.The OAL is .074 different for the two.Last edited on Wed Oct 28th, 2009 11:29 PM by wheezengeezer

6 grains of Bullseye is way too hot for the 200 LSWC, 5.6 is MAX by what Lyman lists, I find that 5.4 is TOO hot.
In my Kimber 1911s, I shoot the 200 LSWC with 4.8 grains of Bullseye, my 225 LRN bullets, I shoot with 5 grains of WW 231.
I prefer the 231 for reloading, but Bullseye works better for me with the 200 LSWC.
The LRN bullet round that I load is the most accurate load for my Sig P220.
