45acp

[FLINTNFIRE]

My friend has a springfield xdm in 45acp , it has a match chamber and I had to adjust my seating for his pistol when he comes to load rounds , I have been extremely lucky in pistols from what I see and read here , and some are unique for loading for ,but then some brands are more cast friendly , I am using lee 6 cavity molds and several other noe and mp , hollow points and solids , as cast powder coated , for the 45acp and a swc hollow point mp mold all function and feed fine and have not determined which is my favorite yet , same with the pistols am shooting rock island 1911 , glock41 , hi point carbine and semi auto thompson and a safari arms with a remington rand slide , use some of those same bullets in the uberti clones 45 colt

Which category do the Springfield XDm barrels fall into?

Springfield says all of their poly framed models feature hardened barrels.

From a loading and shooting standpoint, 1911's like the LBT 230gr LFN a lot. Seat it to where the ogive starts at the case mouth, and there are no problems with tight throats. This also happens to put it at perfect COAL. The feel when they feed is like they're not feeding anything - very smooth. The flat nose also hits hard and it has great penetration capability with hard alloys.4

I've since been playing with the similar NOE Ranch Dog because I wanted the same concept in a tumble lube slug.

The Lee clone of the HG 68 runs great in a 1911! I've been using up some old DuPont 700-X and then I will move on to WST.

I just had that same mold and really wished I could have gotten it to run in my Tanfoglio Witness and Springfield XD Mod2. It was casting very nice and very consistent bullets. The XD wouldn't feed a single round which later I found was an inherent problem due to a design in the slide. Also found that the XDm had a design change made to the slide to remedy this.

I remember that thread.
That is why I started loading the Lee 452-200-RF. It works in any of the pistols perfectly(1911, XD, and XDm).
Any 45ACP pistol I have owned that would feed a Lyman 452374(230 gr RN) would also feed the Lee 200 RF.
It shoots quite well. It just doesn't cut the really pretty holes on paper target that the semi wadcutters do.

My go to bullet is the 452460 SWC at 200gr. I have that mold in the Lyman 4 cav. and I just picked up the 6 cav. clone from MP molds. When the weather warms I will put it to good use.

My 1911 loves that boolit. My striker fired pistols, not so much.

taxman I was finally able to shoot those Lee 200gr RNFP the other day and They functioned well in both the Tanfoglio Witness and the XD Mod2. The witness liked them and shot nice groups, the XD Mod2 didn't like them and shot patterns.

I am now working on a Lyman 452374 RN and once again found it has to be seated very deeply in order to pass the plunk test. Lyman book shows data start length at 1.272" and I have to push it down to 1.250" to get them to seat and turn in the Witness.

The Lyman 452630, or RCBS 201-KT it's discontinued but I saw one on eBay the other day. I like the 200 SWC with a longer nose than the Lyman 452640 or the H&G 68 or any number of other short nosed 200 gr SWC boolits.

I've got somewhere in the neighborhood of 18 different 200-215 gr SWC molds for the .45 ACP.

The RCBS-201KT is my absolute favorite, however it's only available as a two cavity mold. The Lyman 452630 is VERY close to the same boolit, albeit with a beveled base. I finally latched on to a older four cavity mold and it's going to be my goto boolit once I run through the 45 lbs of the RCBS boolits.

I also prefer the RCBS 225 gr RN over the Lyman 452374. The RCBS 225 has more taper in the body, this makes it so you can load it longer in those tight chambers.

I picked up a Springfield XDM competition last summer. It HATES short boolits. Won't feed them at all. H&G 130, Lyman 452460, 452488, and others of the ilk stop that gun cold. It has no problems with the boolits I've mentioned above.

Track down an RCBS 225 RN. It's not as fat.

I am starting to believe this barrel has little to no freebore. If I load to where the bullet just starts to stick in the barrel and I rotate the bullet, when I pull it out I can see a mark just above the case mouth in the bullet but see no marks from the rifling. I've seen this now on the SWC, RNFP and this new RN.

That particular .020 shouldn't matter much in the scheme of things. Just back off the powder charge a tenth or two.
The 45 ACP is a low pressure cartridge. It won't build up dangerous pressures due to OAL differences nearly as fast as a 9mm would.

This just goes to show that each gun makes it's own rules. My XDm competition loves those shorter boolits and shoots them well. Go figure.

Agreed, the Lee 200gr. RNFP I had to seat all the way down to 1.110" when I started and used a AA@2 starting load of 5.0gr and reduced it to 4.9gr and that was still very stout. I now have some tests loaded at 4.4gr of AA#2 and was able to move the bullet out .010" to 1.120"..

Hope this conversation is helping out the OP!

[Win94ae]

Round nose cast bullets don't work in my 45acps, (the wider bullet gets stopped by the lands,) so I use the Lee 200gr SWCs with great results.

[gwpercle]

Lyman 452460 200 grain SWC has worked in every 45 acp I have owned with no modifications to
any :

Colt Standard Government model
Colt Commander
Colt Gold Cup
A 2nd Commander
Star Model PS (1911 w/o grip safety)
AMT Hardballer
Auto Ordnance 1911

That boolit won a few trophies at local indoor bullseye and service matches for me ... I LIKE IT !

The Lee 200g SWC has a very rounded profile for a SWC. I have run it in a couple of 1911s and Marlin lever guns.

From a loading and shooting standpoint, 1911's like the LBT 230gr LFN a lot. Seat it to where the ogive starts at the case mouth, and there are no problems with tight throats.

That LBT looks like an awesome profile!

Back in the day, I used to shoot this bullet in all my 1911s, even the ones that belonged to Uncle. With just a little bit of polishing done to the feed ramp, an otherwise stock 1911 would gobble these up! I still use this bullet, but I don't have any 1911s that belong to Uncle these days.

[maxfam]

My Dan Wesson 1911's like a 200 grain flat point that is actually a 45Colt bullet. I haven't cast for the ACP yet. I will sometime soon.
