Mine likes the 200 grain hard cast loadings directly from DoubleTap (I do not reload yet). Maybe if you download it to about 1150 fps like he does they'll work?

I don't like hearing this because that's one of the first loads I wanted to load up myself, the 200 grain hardcast bullet DT uses at 1200fps.  :(

I have 50 WFNGC's left.  I am going to try to replicate their factory load and seat the bullet a little deeper as well.  Based on some of shadow's pulldowns it looks like DoubleTap's factory load is a little shorter than 1.250.  When you put the bullets side by side with a 180 grain gold dot or a 200 grain XTP you can see how little taper the WFNGC's have.  Casual observation would lead me to believe they would be more difficult to feed, and my recent experience backed that up.

The funny thing is that my Gen 4 feed that particular load better than the gen 3.....but that is not saying much.  The Gen 4 hated everything.  My Gen 3 only hates that particular load. :)

I may search through the reloading section and see if anyone has experience with the 200 grain WFNGC's and has had good luck with them.

Double Tap actually had to shorten the COAL to 1.2420" to get that wide Flat Nose to feed more reliably.  The tipping angle with the wide nose makes it too long at the normal COAL...

That is good to know.  I was given some load data from Double Tap's production manager.  They were blue dot and 800-x recipes.  He advised me to use 1.250" as the COAL with CCI 300's.  Interesting that they seat their factory loads significantly deeper.......they also appear to use Longshot in their factory loads.  I actually like Longshot better because I don't have to hand weight each charge like I do with 800-X.  I can get longshot to meter almost spot on 100% of the time.  I give myself 2/10ths of a grain "fudge factor" and I feel comfortable metering longshot pretty close to book max.  I check every 5th round when I am working close to book max.  haven't lost any digits yet :)
I know this is a discussion for a different thread, but I wonder what the pressure increase would be going from 1.250 to 1.2420?  I had no signs of pressure with 9.3 grains of 800-X, CCI 300's, and my once fired Armscor brass.  Primers were in perfect condition, no bulges on the brass fired through the KKM barrel and only very very slight bulging with the stock barrel.  I would not even consider them a "smile".  Love the KKM barrel by the way :) I may load up my last 50 WFNGC at 1.2420 and back off the powder a tad and see how they feed.
