Trying to load some. Bayou bullets 95 grain using Win 231 can’t find anything in my Lee manual or Speer or Hogdon thanking you all a head of time
 
My Lyman list a 90 and 105 lead bullet with w231 but not a 95gr lead bullet.
You should find data some where...........

I would help but I only loaded 125gr lead bullets.

They are a lead bullet, right?

I only information is for jacketed Bullets I am trying to use 95 powder coated lead

Conventional (haha) wisdom is to back off jacketed powder loads a little for lead. The 5.5 gn load should be fine. What you will need to ensure is that the OAL of the short bullet feeds in your gun. I use 100 gn Cowboy .358 bullets in .357 cases in my Henry Big Boy and have to seat them well out to feed reliably.

Another aspect would be that 9mm barrels are designed to stabilise heavier bullets, so your 90 gn’rs may not group too well except at contact distances.
 
+1;

My 9mm's did not do well with bullets less than 115grs.

Even a Hornady 100gr fmj at 1.08 to 1.12" OAL with Bullseye and Unique
could only come up with a best group at 4.5" at 15 yards, for me.

Good luck........
at least you will have a clean barrel.
 
Lyman shows 3.8-5.1 grs of 231 with a 90 gr cast lead bullet. If you stay
a few tenths below the max of 5.1 for the 90 with your 95 gr bullet you
should be fine.
 
OK I got Dennis of Bayou Bullets he said to start 3.8 of 231 and Max of 5.1....real nice guy I will try to run some off and tell you how I did thats all for now until then.

I've loaded these exact same 95gn Bayou bullets using HP-38, same as 231. I wasn't impressed by their accuracy through my Shield, or R1 1911, flyers galore. I started with 4.2gn and went to 5.0gn with the best achievable accuracy being 4.6 to 4.8gn. They all cycled the pistols though. Bullseye powder is what I use with these bullets now. 4.5gn of BE is super accurate with a velocity between 1100-1200fps, depending on the pistol. Oh, and I load them to 1.020" OAL.
 
I have had lots of problems with bullets that light. Some will not operate the slide and others are so short they won't feed. I have pretty well given up on them.
 
I'm actually kind of curious as to using bullets that light in a 9mm.

Personally, I found a PC'd 147 over 4.1gr of Power Pistol to be reliable and quite soft-shooting. Very often, heavier bullets feel nicer in the hand to shoot.

Same here. Heavier, slow moving bullets give more of a slow rolling recoil impulse, while very light, very fast moving bullets give a sharp, quick recoil impulse.

THIS^^^^^

The OAL is 1.045" for the lyman 356242 90gr bullet.

Look familiar? A picture of the lyman 356242
.356" 90 Grn. RN Lyman 2-Cavity Mould #356242 - Buffalo Arms

The difference in the OAL's is more dramatic then a +/- 5gr difference in bullet weight.

That lyman bullet will very +/- 3gr depending on the alloy it is cast with (pure lead VS lino-type). Then add +/2gr if powder coated or +/- 5gr if it used with traditional lube in it's lube groove.

When you can't find any data for the bullet you're using look at use the data for a lighter bullet and pay attention to the oal's. With coated bullets look at cast bullet data 1st.


The other thing most reloaders don't look at when they can't find data for their specific bullet is to look at a blanket powder weight for the powder being used. WW231 is a fantastic powder that doesn't have pressure spikes at it's upper end. Myself I would of used the lyman 356242 data (oal) and adjusted the oal via plunk test. Then I would of used a 4.0gr load of ww231.


Why 4.0gr of ww231???? It's that blanket power weight thing
90gr jhp min 4.0gr max 5.1gr ='s 4.0gr safe
95gr fmj min 3.7gr max 5.1gr ='s 4.0gr safe
115gr jhp min 3.5gr max 4.9gr ='s 4.0gr safe
115gr barns tac-xp min 3.5gr max 5.0gr ='s 4.0gr safe
124gr jhp min 3.8gr max 4.5gr ='s 4.0gr safe
125gr jhp min 3.9gr max 4.4gr ='s 4.0gr safe
147gr tmj min 3.5gr max 4.1gr ='s 4.0gr safe
90gr lrn min 3.8gr max 5.1gr ='s 4.0gr safe
120gr lrd min 3.0gr max 4.1gr ='s 4.0gr safe
120gr ltc min 2.9gr max 4.4gr ='s 4.0gr safe

Bullets weighing 90gr to 147gr an all use the same 4.0gr load of ww231.
 
I'm not sure what you guys are looking at but the Hodgdon load data site shows data for a Sierra 95gr bullet using W231, I'm looking at it right now.
 
"Another aspect would be that 9mm barrels are designed to stabilise heavier bullets, so your 90 gn’rs may not group too well except at contact distances."

You have it backwards. Longer heavier bullets are more difficult to stabilize than shorter lighter bullets, and require a tighter rifling twist. Any rifling twist adequate to stabilize a longer heavier bullet will certainly stabilize a shorter lighter bullet.
 
Great Post, IMHO! But...

My only reservation has to do with the line directly above the graph: beginning with "The difference in the OAL's is much more dramatic..."

That graph is not only showing the differences between two bullet weights ("+/- 5g"?) but also TWO DIFFERENT CALIBERS, 9mm & 40 S&W.

The slopes of the two lines have more to do with that factor vs. differing bullet weights...

Great post, though: especially the "4.0gr safe" part!

Cheers!
