.45 acp and 200 gr. SWC loading
 
I wanted a load with a 200 gr. swc and it would not cycle in my Cycle in automatic. After numerous trips to the indoor range I figured it out. The load needs to have a shoulder of 1/8" to cycle. The load itself was extremely accurate and I used win. 231 with 5.2 grs. The OAL was 1.21. If you try this load please let me know ok. Semper Fi!

I just loaded Speer 200 gr LSWC for my XDm .45. I loaded them per the Speer manual and they cycle fine. I believe my OAL was less. I will check this evening and let you know.

What gun are you loading for?

I am loading for a ruger p 90 and it is extremely accurate with cast bullets. I use a lee mould and the one with which you use the alox lube and I do not have to size them at all. I am going to try 5.3 grs. And 5.4 grs. Of win 231. I have tried bullseye, unique, blue dot, hp38 and none were as accurate as win 231 in my automatic. Semper Fi!

You are a little hot at 5.2 gr. Not dangerously, but warmer than necessary. I use 4.5 gr with a 200 gr (If memory serves) and 5.0 with a 225 gr.

If you are going to load SWC,s in .45 acp remember to leave a small shoulder on the bullet or it will not cycle in the Auto. I found this out the hard way! Good luck reloading. I am so glad that there are still guys who reload!

The standard OAL for the 200GR LSWC is 1.250. This is where you should start and this is where you may end.

1.210 is abnormally short.

Did you check your OAL with the barrel like this?

Amen to that. I tried some 185 SWC's, and according to a suggested load in my Hornady book, it said OAL should be 1.135 using 6.1 gr Power Pistol.
They would not cycle at all. I finally found, after many trials, using dummy loads, that 1.23 worked really good, and I upped the powder to 6.8 grs. Went to the range, and had one failure to load out of 20. The other 19 cycled and fired with no problem, and was a nice lower recoil to boot.

Auto's (rimless), head space on the mouth of the cartridge, if you roll crimp or taper crimp too far then head spacing is lost and FTF usually happens. Bullet design matters not.

With a L-SWC, I seat such that the bullet just "kisses" the lede/rifling. This is usually about 1.24-1.270", depending on the design, with most being right at 1.265".
Best bullets I have found are the RCBS 452-201-SWC and the Zero 200gn swaged SWC. Both have the long nose like the H&G #68. I have not found the older "button" nose SWC to be as accurate or to feed as well.
