normal for the LFCD which is why many dislike it as they claim it is resizing the bullet. It is the carbide sizing ring on the bottom, Some bullets you will fill it touching, others you will not.
Let the flames begin, I am getting popcorn!
But as Lee indicated, they were meant for jacketed diameter bullets and if you are using larger sized lead/coated lead bullets, you should order larger ID carbide sizing ring FCD or have yours modified IF your FCD post sizes finished rounds too much.
If FCD is indeed post sizing finished rounds, I would be concerned about reducing bullet diameter and reducing neck tension which will result in bullet setback during feeding/chambering. You can measure OAL/COL before and after feeding/chambering from magazine but if there is no reduction in OAL, you are good to go. If you see significant reduction (more than a few thousandths), then you have neck tension issue and may need to set the FCD aside.
But, I did find a good use for one. I plink with 38 Special wadcutters loaded in mixed cases. Occasionally, a case would have a heavier wall and the resultant cartridge would not chamber. i'd set the cartridge aside and run it through a 38 Special FCD die when i got home. All fixed.
Thanks, makes sense, I'll definitely check the OAL before and after cycling some rounds through the gun, good stuff!
I would say run a quick test and see what your results are for you gun and your load. If you are concerned about the ones you "feel" separate them out and do a test of them vs the ones you don't feel or against rounds you did not use the FCD on. The results will show whether you need to be concerned or not.
SAAMI puts you right at maximum diameter. http://www.saami.org/PubResources/CC_Drawings/Pistol/45%20Automatic.pdf Common diameter, like my "seat" measurements. [/URL][/IMG]
is adjustable to get as much crimp as desired. If you are concerned, use it just to knock down the case flare. I've never experienced any setback from the manual thumb push on the harder crimped cases or during firing. I do load a bit of lead and prior to the FCD would experience the rare bullet that would not fit the chamber. One instance shooting my 45 series 80, the chamber I load for, and my brother's 45 actually used in the 'Battle of the Bulge', the WWII gun wouldn't chamber, at least easily, any of my loaded rounds due to, believe it or not, a too tight chamber or, maybe I should say the series 80 has a large one. This was with a 500 count box of GBC semi wad cutters. They were supposedly .452 but measured between .452 and .453. I ended up shooting the rest all up in my Series 80 and they all shot extremely well. I tightened down on the FCD on about a 100 rounds and they all chambered and shot flawlessly in it the next range session in both guns. My next refinement is to use the new Lee Push Through Sizer Die that I bought for resizing self casted powder coated bullets and run all those different lead bullets I've bought from various casters during the Obama lean years to assure they are all sized correctly to start with.
Cast boolits take even a little more finagling to keep the case from swaging the boolits down. I had to get a slightly larger expander ball made so I could keep cast boolits at .001" over bore diameter.
But for the OP, I would suggest the "plunk test" as the final test of the reloads. .473" may not br too big for your gun. I haven't measured the finished case mouth, ("crimped" with a plain old taper crimp die) in many years, just using the "plunk test"...
Not a fan of the FCD?
Assuming your cast bullets are to spec (.452), that post seating resizing is not necessary. How much its resizing varies on the case wall thickness. I cast and size all calibers to spec, and I want them to stay that size until they hit rifling.
I do like crimping on stage 4, so I have knocked the carbide ring out of every Lee FCD for every caliber I load. All the FCD does is crimp, none of that post sizing nonsense.
