Curing this Jam in 45ACP...Longer or Shorter COAL?

I've read several forums that state that Semi Wad Cutters don't feed reliably in some platforms. I want to know...generally speaking for any semi auto pistol...if you get a FTF such as the one below...Case head down at breech face angling projectile up toward "roof" of chamber...in a firearm that should feed this type of projectile...Would the reloader lengthen or shorten total Case Overall Length to remedy FTF issues...or is there no general rule, and trial-and-error reigns supreme?

Just looking for COAL opinions...NOT opinions like "choose another bullet."

I usually load SWC bullets as long as will fit in the magazine, so I'd start by increasing OAL. If that doesn't work try shortening it. IF both fail choose a new bullet, sorry but that is the way it is.

I seem to have better luck with some magazines than others with this problem. Not sure why.

Which gun? If its a 1911 the mags with bad "luck" likely need new springs.

For a while I gave up on LSWC in 45 ACP. I had the same issues plus I wanted them to work in any 45 I had. So I just used flat nose as I did not want to tune ammo to each gun.

On the main 1911 I used it was trial an error.
It was pretty much seat the bullet until there is just a fingernail edge of the driving band showing. It literally was thousandths of an inch or so between go or no go.

I had them way to long to begin with. Of course it will vary with each brand of bullet and barrel.

Mr WalkAlong is best qualified to answer this one!

The owner of Magnus Bullets helped me a lot and I saw the light!:)

Extractor may need adjustment. Check case head diameter, should not be larger than .480" http://i338.photobucket.com/albums/n420/joe1944usa/BoltFace.jpg

I allow only a fingernail width of the shoulder outside the case. For my pistols, shorter worked better with lswc.
243winx may be on to something with the extractor. Will your pistol feed empty cases when the slide is worked slow?

I also tend to go as long as possible in the .45ACP. My 1911's like 1.260 with a 200GR LSWC projectile.

Load too weak.

There are SWC bullets, and then there are SWC bullets.

Some, like the old H&G #68 200 grain, and the Lyman #452630 200 grain, replicate the same exact nose ogive contact in the chamber of the 230 grain military RN-FMJ.

As such, the bullet nose is driven down by the top of the chamber and they feed slick like owl snot through most guns.

Others, like the Lee 200 SWC, have no basis in reality to the 230 FMJ-RN bullet shape chamber contact patch.
And some guns won't feed them worth sour owl dodo.

Even some guns that feed everything else including empty cases.

:confused::confused:

I was not aware of the specific density and viscosity of Owl Snot contributed to the feeding of lead bullets in the 1911? How does it compare to Goose Grease?:D;)

LOL...not interested due to having to 2500 of them...when they're gone I'm done with SWC's

I seemed to run into feed problems from not crimping the brass enough, if any at all. I realized I was not cycling the shell all the way up on the lee classic loader and not getting a crimp to remove the flare of the shell.

I needed just a tad of crimp to give me a parallel or slightly crimped in to make the shell slide better in the cycling.

You might try that?

be safe.

In mine, limited to Bayou coated as the only LSWC I've used, I use the barrel and a dummy round to find the landings, and seat approx .015-.020" off the landings. I have had zero FTFeed issues, but that is probably due to bullet construction over all else.
Use a dummy round to find the longest allowable OAL in your gun, Then you can use the dummy round to find out if it feeds reliably any where between your guns max OAL and your current seating depth and shorter.

Extractor has a sharp corner on the lower edge?

Have you tried a different magazines with a different lip and followers design. Not all are equal when it comes to feeding LSWC. I normally find the shorter OAL feed better but every gun/mag/bullet combo can be different.

I looked at the magazines that worked for my LSWC. The follower is different. Thanks, that helped explain my "luck" issue.
