200 grain FN lead bullets 45 ACP and 45 Colt.

[Rule3]

These have a crimp groove so no problem with 45 Colt in a revolver/ But for the 45 ACP and taper crimp. How do you adjust the crimp so it doesn't go to far in the crimp groove so the round will still headspace on the case mouth,? I used the MBC version years ago but do not know if they were spacing on the extractor??

Is the crimp groove in the correct place for the 45acp?

Either seat them to the base of the crimp groove, or seat them to your liking and adjust your taper crimp to take away ONLY the flare...

Calipers will let you know...

You may not be in the crimp groove with your prefered length....

Try to seat so the case rim is just above the crimp groove. Start low and work up on the powder charge, stay below the start of the ogive and make sure the load passes the plunk test.

luck,

I'd try to land the taper crimp on the driving band if posible. As long as it fits in your magazine and doesn't hit the lands in your barrel, they should work fine.

The SWC cast bullet would not feed in either my 45 Witness or my wife's 45 XD Mod2 so I went with the Lee 200gr RNFP and it shoots perfectly as you see it loaded here in both guns.

I found that the 200 grain SWC and the RNFP both fit and feed properly with my SA Range officer. They also feed but don't shoot well in my four 45 Colt Lever Guns. But I have lots of them and won't mind using them up in my 1911. I do a light crimp just to remove the bell like said earlier.

Those look similar Lee's 452-200 that I cast. 1.100, IIRC, is what they would plunk test in a P345 barrel. In the 8-rd magazine, they cycled fine as long as I didn't go above 6 rounds in the magazine. A very blunt nose. Wider meplat than MBC's 200 gr. FN.

It is a Lee 452-200 RNFP. Leaves nice clean round holes in paper. With range scrap it drops @ about 205gr.
