The rule for seating depth using a LSWC bullet is to have the shoulder of the bullet about a thumbnail thickness above the case mouth. COAL isn't important. If you leave them seated out that far the bullets will likely jam into the rifling causing it FTF. As for the crimp all you need to do is remove the belling necessary to seat the bullet. A manual will give the correct dimension but using a case gauge or your barrel will tell you if it's right. How light is your load? I also use a 200gr LSWC over 4.5gr of WST. It is a very controllable load and will make major power factor if that becomes an issue. I use it for plate matches and shooting fast is no problem, plus that is a very accurate load. |

It may be the bullet profile that makes them look long, I don't know. I've always loaded LSWC out to ~1.25 and they usually looked liked dryflash3's' rounds. These particular LSWC's are from Precision Delta and they are the first to stick out on the shoulder that much at 1.25. As far as feeding goes, they all pass the case gauge and I've shot nearly 500 so far with zero issues. If I decide to load them shorter, can I just run them all back through the seating die? |

If your gun eats em up without a problem then you don't have one. .007'' variance is not very much, you could be putting more pressure on the handle on some than others.
I seat my 200 SWC's at 1.265'' and all of them function flawlessly in all my 45 Autos. Because those bullets don't have a lube groove and there's damage to the shoulder and nose I'm kinda thinking they are swaged lead which is very soft. If they are seated too far out the recoil spring has enough force to ''make them chamber'' due to the soft lead. Do these rounds fit the chamber or case gage easily ? If so, then go ahead and shoot em all. There's no magic number that is used to seat bullets to except the one that fits your gun(s) the best. |

Now that you mention it, Precision Delta did describe these was swaged, not cast. The Hornady seater die came with two stems, one with a concave surface and one with a flat surface. I figured the flat surface one was for flat point bullets. My Lee dies had only the concave seating stem and my OAL's were even more random. But since the opinion is that such a minor variation does not really matter, I'm not going to worry about the various lengths as long as they are all in the same area. |

Using soft cast lead bullets can and will cause leading in your barrel. If the slide is forcing the round into battery pushing the bullet deeper into the case you may also find lead built up at the end of the chamber. Not having lube will cause leading to build up quicker. |

What kind of accuracy are you getting???
I had a batch of 200 swc that had lousy OAL,so who ever cast them may not have had the best molds etc... Anyhow they shot very well. I did go nuts adjusting the dies until I found out as long as the crimp was correct you are good to go ! |

Rounds measured were always rounds that had been loaded with other rounds at all five stations.
As far as accuracy goes, they are probably more accurate that I am. If I take my time, I can hit 6" plates at 15yds consistently. I'd have no way of knowing their true potential unless I had someone more competent than me shoot them. I have not noticed excessive leading in my barrel (yet). I have about 200 down the pipe followed by a magazine of hot FMJs and I can see no appreciable buildup. As in to say, I have yet to clean it since my last range trip haha. The LSWC's are only loaded over 4.6gr of WST and I'd be surprised if they were moving faster than 950 - 1000fps. |

I first noticed they looked seated far out. After comparing pictures, I realized the shape of your bullets is very different than the SWC's I use. With the same OAL the "ledge" of your bullet will be further out of the case. If it gets too far out, it will hit the rifling and not completely chamber the bullet.
The lack of a lube groove seems very odd. It is like your bullets were meant for a moly coat or some other means of lube. |

The 200gr LSWC I use with 4.5gr of WST are about 850fps. The leading problem isn't from pushing them too fast, it's from your bullets being soft swaged lead. When you pull your barrel run a wet brush through it followed by a wet then dry patch to remove the fouling. Hold the end of the barrel up where a bright light shines through and look for gray streaks. That will be lead. There are several ways to remove it but I just wrap a small amount of a copper Chore Boy pot scrubber around a worn brush and scrub it out. For the chamber I chuck the cleaning rod into my cordless drill and spin it for a few seconds. It works. As for accuracy the bullets I use and my load through my pistol with a reddot optic I can easily keep my groups around 3" at 50 yards. I shoot falling plate matches- 8" plates at 25 yards. I average 6 plates in 4.5-5 seconds with excellent accuracy. |

They come in some sort of dry lube tumbled on them, they didn't have lube rings in them like a lot of other bullets do. |
