Recommended Posts

I have been using w231 exclusively for my STI 5"

Brass: Mixed

Bullet: 180 grain Bear Creek Bullet FP

Primer: CCI SPP

Powder W231 4.7-4.8 grains

COAL: 1.175-1.80

Crimp: .420 ish

I really really need to get out to the range and chrono this load to see if I make major.

4.4 - 4.5 grains with lead moly coated Magnus bulltes gets you right to 170-172 PF in a 5" 1911.

5.0 grains with FMJ's out of G35 will get you to 170 PF.

Both loads with Fed SPP and mixed brass.

Recommed you back off by 10% and work your way up with you gun.

Bullet weight??

Sorry, all 180 grain, COL is max per reloading manuals for 180 graim Conical FP (I'm not at home so I can't measure and confirm)

I run a 180 with win 231 in 40 makes 170 pf consistently out of my p16.

180 gr lead flat point projectile

4.9 gr win 231

1.125 OAL

WSP

Range brass.

If I remember correctly this makes 175-178 often at the chrono. I am planning to back it down a little this shooting season to see if I can help speed up my second shots.

Start lower and chrono.

Does it shoot flat?

I will start with your data, then work it. Thanks

I use 5.2 gr. with a 230 gr. FMJ bullet.

Win. brass and primer.

I am shooting a 5" Sig 1911 Target.

.45 ACP?

Ooops, sorry. I am new here and my brain hasn't acclimated yet.

That was for my .45.

However I still use 5.2 gr. of 231 for my 165 gr..40's.

Sorry about the goof up. I need to pay more attention. :eatdrink:

Hmmm. Honestly I am not sure how 'flat' it shoots. Not very is my guess.

90+% of all the shots in USPSA are under 50 yards and in those distances I hit point of aim. I am now fascinated by the question if you can wait until this cold snaps I will do some POA POI testing.

Retread--don't read too much into that, some one is yanking your chain because you are running 178pf. I kind of wonder why also, but it's your gun and your game.

Absolutely my game. The question is does 8 Pf make the gun just a little harder to control? Sure does it make 1/10 a second difference over a course of fire? Maybe. I would like to drop the PF a little and see if things get easier. Just me.

Wanted to get to range again and recrono my load, haven't had time do to all the snow. Should of said of also stated that my powder is at least 15 yrs old. That may be why my grns. are a little higher. As always you should start out lower and work your way up. I wouldn't give anyone wrong information on purpose. I was just stating what I'm using now

I think Rob posted a rather optimistic load for 180 lead with W231 - I think you are not going to get Major reliably until you hit 4.8 gr and may need up to 5.0. Rob - better rerun the chrony on those.

Sorry, Jim I'll stand by my numbers. I did test the 180 gr Moly coated lead w/ 4.8gr W231 and got 177PF out of the M&P and 182PF out of the 1911.

Both guns delivered 170-171PF at 4.5gr w/ the 180 gr Moly lead.

IT was a cool temp day so I will double check on a warm day.

If the choro is off then I screwed no matter what.
