Duplicating factory .45 acp
 

Hi Folks, What would be a good powder charge using Win 231 with a 230grn FMJ to equal Winchester white box? I recently bought a new Springer Mil-Spec & it's too stiff to cycle my light load 200grn swc's.(I'm not looking for anything hot) Also what is a good OAL for this load? This pistol works great w/factory WWB. Thanks for any info-Dave

The maximum OAL for .45 ACP is 1.275, I have never used W231 on the .45ACP so I can't help you much there. I usually use 5.5 grains of Titegroup and have good results with it. If the light loads won't cycle the Springer, then you do need to go a little hotter.

Lee 2nd Edition:: 230g FMJ Minimum OAL 1.190 Max OAL 1.275
Win 231 Start 4.8g 740fps
Max 5.1g 785fps

What you could do is measure the OAL on a factory case, read the average fps on the box, then chrono your loads till you have as close to a factory load as you can.

Personally i don't handload for accuracy in pistols. All I do is take the lee .05cc scoop, dip it in Winchester Auto comp and call it good. It works good enough for this guy. It is a little hot but my Para eats it up.

1.272"

5.4 gr W231/HP38 or 5.0 gr Bullseye

Both will propel a 230 gr ball at 850

BTW, the 5.4 gr load of W231 under 230 gr ball in the .45ACP is Mike Venturinos go to load for 1911 .45ACP pistols...

Re: Duplicating factory .45 acp
 

Original factory loading for the 230 gr. RN is about 850 fps. Look in your manual for a load that duplicates that velocity...

Its kinda weird to look in my manuals and still see HP-38 and W231 listed with different data. Go figure. Hopefully in future manuals they will have addressed that issue so as not to confuse me.:confused:

Thanks Folks for the info-Dave

I wonder if Springfield offers a lighter spring for cast loads like I got with my Colt gold cup. They gave me a regular spring & also a green colored one that works great with light cast bullet loads.

Re: Duplicating factory .45 acp
 

Work up a load with 231 in your gun and see what it likes; I do agree with JLA that 5.4gr is a great load for 230 ball, you'll probably end up somewhere around there. Who cares what WWB does, it's not that great; work up a AMB load !! ( Azleite My Box - others can go get their own :D)

great advice worm

Re: Duplicating factory .45 acp
 

I wonder if your springer needs a bit of breaking in, I shoot 4.5 gr bullseye/200gr plated SWC in my A1 and a wilson 18lb recoil spring produces no problems cycling. If reduced loads is what your after, buy a lower LB recoil spring to accomidate.
