WST is my go to powder for 45 auto. I load 4.9 grains under a 200 grain LSWC. Accurate and very clean.
Anyone with Load data for MBC 200gr RNFP XD #4, 45acp?

I loaded them with 5.0 gr HP-38 and they were perfect in everyone of my 45's. XD and XD Tact, Sig 220 and two 1911's. I like them! I might try a little higher powder charge.

My Pro Auto Disk will throw 4.9 and 5.2 gr of W231/HP38 using .46 and .49 disk holes. I have tested the 200 gr RNFP XD#4 at both charge weights at 1.195" OAL against my 200 gr SWC at 1.25" and both charges shot well.
I've been shooting more of these Cowboy #4 bullets lately as well as the Lee 452-200-RNFP variant lately. The Lee has a shorter nose and a larger meplat, thus the distance from the crimp groove to the nose is shorter. I'm still popping them off with 4.9gr-5.0gr of HP-38 (depending on humidity it seems) but I want to *safely* practice more in the full power / +P spectrum for varminting.
My Lyman's 49th doesn't have LRNFP data but offers their 200gr #452460 SWC seated to 1.161" which is very similiar to the 1.168" I seat the Lee bullet at. It lists a minimum of 4.0gr of W231 @ 694fps and 6.0gr @ 987fps tested from a 5" universal receiver ignited by CCI #300 or Remington #2 1/2 primers. In my XD, stovepipes occur at anything under 4.6gr unless I throw my TLR-2s on the accessory rail to weight the muzzle a bit more. Knowing how my gun performs in relation to the rest of the cast bullet data in Lyman's #49, I'm inclined to try 6.0gr - 6.6gr loads in .2gr increments. This is also considering that the 6.0gr/987fps result they record is only at 18k CUP when the SAAMI standard allows up to 21k for +P which the XD is rated for.
Anyone else load either the MBC IDP#4XD, Cowboy #4, or Lee 452-200-RNFP for full power or hunting use?

I have not loaded them at 5.6 grs of HP 38, but would not have a problem doing so.
Looking through some manuals, you can get a little more velocity with different powders such as Accurate #5 and #7 and Blue Dot. Based only on a 200 gr lead bullet, not this specific one.

Good thread - glad I saw it. A co-worker bought his first handgun, a 45XD,a year or so ago. I had helped him get set up for loading some rifle ammo before that, so I gave him a box of 200 LSWC and a bag of bullets.
We were out fishing after that and ended up shooting that box of wadcutters. His XD would not consistently cycle them, and I thought the factory spring might just work with hotter ammo. Anyway, I emptied the box with my 1911 so he would have the brass.
Now, I read here that the XD doesn't like SWC bullets. So, I have an old bucket of 230 LRN I have never loaded. I think I will give him those and take back the SWCs.
Maybe I'll load some so he can try them. Should I also load them "short", under 1.2" for the XP, or is that just a flat point need?
Thanks all

Tried a 25 round batch of Lee 452-200-RNFP bullets and 25 of the MBC Cowboy #4's tonight at 5.6gr and neither even felt like factory Winchester WWB. One thing I will not however, is that the Lee blew through 9 milk jugs filled with water and disappeared. I wasn't expecting that one! The first jug was completely blown apart, the second and third were ruptured/split and the rest had perfect "cookies" of plastic, reminiscent of what a SWC does to paper, just barely hanging on.
Gonna try a few smaller batches working up to 6.8ish grains for this weekend and see if that feels more "factorylike"...

Have been using the 200 lrnfp in semi's for some years. 1.178 Col, 5.0 hp-38. The commercial 200 lrnfp's being used are reduced dia in front of the cannelure, but am able to taper crimp them and still have enough outside finished diam to headspace on chamber mouth. Use these bullets and hp-38 for 45 acp, 45 ar (5.8 gns hp-38) and 45 Lc (7.5 grains hp-38).
The 255 lrnfp can make some exceptionally accurate loads in 45, but the commercial varietys tried are full dia in front of the cannelure, which dictates the COL loaded to. The Lee 255 lrnfp has a wide flat cannelure on the front, the pics of the Lee 200 lrnfp look to have a similiar flat nose?

It's my understanding that both the 200gr and 255gr versions are identical with the exception of the second added lube band and extra weight on the 255gr. My 200gr mould throws boolits that measure right at .4525" in all 3 places, ahead of the crimp groove, between the crimp groove and lube groove (first driving band), and also after the lube groove (last/second driving band).
