Reloads for P220 in .45 ACP

Hey guys and gals,

Greetings from the PRNJ.

I am starting to reload for the Sig P220 in .45.

What kinds of loads do you guys use? I am looking for a load on the lighter side but that can still operate the slide. I am also looking to use lead SWC 200g bullets. Is that a good idea? Will they feed?

This kind of info isn't in the manuals.

Thanks for getting me started,

Marc

Hi:

Welocme from an ex-Jerseyite myself. {'escaped in '81. LOL.}

I have found that both the P250 I used to own and my current P220 .45's functioned poorly with LSWC's. I finally figured out the problem was the rim of the case being extracted would strike the case mouth of the round rising up from the magazine, turning a lip on it. This lip then prevented complete chambering and tied up the gun.

I handload mostly 230 grain LRN's now, plus a smattering of 185 JHP's and occaisionally the old Lyman 454190 Army semi-pointed bullet {old style mold} which weigh 262 grains cast of wheelweights and loaded to 825 fps and used for killing butcher stock penetrate very deeply.

I load 45 for my P220 and my sig 1911. Do not use LSWC. The rim of the bullet ( the part that makes a nice round hole in the target) gets hung on the feed ramp easily.

If cost is why you are going for LSWC, check out RockyMountainReloading. RMR bullets. They sell plated bullets cheaper than lead and ship free. They also are great quality.


With the 200 grain RN I use 5.0g of HP-38, or the same charge of Win WST. Check this out

http://data.hodgdon.com/main_menu.asp

Lots of good info here


People who ask me why I buy Sig Sauer guns probably never bought one

Thanks

Thanks, guys

I will stay away from the SWC. I just wanted the SWC to make nice holes in the paper - remembering my revolver days. I prefer the jacketed / plated stuff anyway.

Thanks Valdemar and C17 for very valuable info. RN it is and Hodgdon and Winchester powder will be tried (if I can find any).

Now I can go to the manuals since I have an idea what will work in the P220.

Thanks for the welcome, bearone2.

Have a great Christmas !!

I use Unique almost exclusively in .45 ACP, but there are lots of good options.

You may find availability determines your selection.

Merry Christmas to you, too.

I tried w231 with a 230 PD fmj and it was way too dirty for my liking. I switched to WST for 45, and it's way cleaner and meters great.

I chronoed one of my loads: 4.7 wst, 230 pd fmj rn, 1.26 oal, mixed brass out of a Glock 21 stock barrel = 720-740 fps....

I wish I would have tried some 5.0gr loads to see if theyre close to factory... will next time

I load plated and jacketed 230gr RN on my Dillon SDB---8.0 gr of AA#5 @ 1.250 OAL. AA#5 meters well on my machine & I get consistent cycling in my guns with no problems in my Sig 220, 220 Elite & Sig Ultra compact. I don't load any lead at all.

I use the 200 gr. SWC on all my 45s, including 2 P-220s and a P-245, and they feed fine. The " secret" is to crimp the case mouth deep enough into the bullet so the rim of the extracting round does not have a "lip" to hit. Not my idea, but mentioned years ago by Ross Seyfried in a reloading article. And no, the 45ACP does not headspace on the case rim! If you don't believe it, just measure the case length of your cases. Good luck finding any common length. I gave up measuring 45 ACP cases more than 20 years ago with no problems in that time.

You are dead right about the case length issue.

I've shot other crimped rounds in .45 ACP with no trouble but due to the depth of the lip turned up never thought about trying it with the 200 LSWC. Might have to give that whirl!

I hand load nearly all of my 45 ACP ammo. Personally, I would never run lead bullets through any of my auto pistols. They are quite dirty and I do not feel like cleaning all of the lead off the ramp and barrel. Stay with at least FMJ rounds. You can find them pretty easily now in 200 and 250 grain. I know that Midsouth Shooters had Berry 230 grain FMJ in stock not long ago.

I should also state that I have quit run cast lead bullets through my revolvers. It's not worth the headache for me when I have to clean them. The oils on the bullets cause them to be incredibly dirty.

Just a post from the other side of this issue.

About all in terms of total numbers I run thru my autos IS lead. There is more smoke, but I have no problems cleaning at all. It's a snap.
