Picking powder for an older Dillon measure.

H110 is doing well as my current powder, but I'm thinking a coarser grained one might not bind up the powder measure of my Dillon press quite so much?

So after all sorts of research I've narrowed the "perfect" *ahem* load down to a few choices & I'd appreciate you honest input from anyone having used them in a Dillon measure. It is the older version without the Teflon surfaces. These will all be fired in a .357 S&W magnum DW 15-2 with the 6" VRHB barrel. I'm going for 1350 FPS too BTW.

I'm going with Starline brass, Winchester WSPM primers, & Hornady 125 Gr XTP bullets. These components are already picked so I'd like to match the powder to them, not to change them for a "better" powder.
My choices seem to be:

W 296, 19.1Gr

N-110, 15.3 Gr

Herc. 2400, 16.4 Gr.

Which would be your preferred pick in a Dillon measure & why?
TIA for the suggestions.

H110 & W296 are the same. The powder bar spacer has given me a problem when not installed with the correct side up. It looks to be the same, but it works better the one way. All 3 powder will work in the RL 450. What "old" Dillon do you have? http://photobucket.com/rl450schematic

I'm using the new Dillon powder measures...so honestly, I'd suggest you call Dillon and discuss why your measures are binding up using H-110. I don't know how the old measure differed...or if they have a fix for you ...but I'm confident they'll be helpful to you.

I'm also assuming that you're talking about loading a .357 mag load....with that 125gr bullet .../ in your Dan Wesson revolver ....but I'm a little puzzled by your 1350 fps remark ....because with a 125gr bullet in .357 mag ....most loads are pushing it up around 1500 - 1900 fps...?? but 1350 fps seems too fast for a .38 spl load ...so I'm wondering what you're doing ??

so I guess we need to know - are you looking at .38 spl or .357 mag cases... ??

but whether your loading .38 spl or .357 mag ....I'd really suggest you consider a powder like Hodgdon Universal .... I've been using a lot of Hodgdon Universal ...in handgun calibers from 9mm - up thru .357 mag and .44 mag...for the last year or so. In my area, its easy to find...and reasonably priced.

The ignition properties on H110 ...make me a little nervous on handgun loads...where the Hodgdon book says never reduce their recommended loads more than 3% from the max ..../ so the only thing I use H-110 for is in .410 shotshells ----- so I think moving away from H110 makes sense to me.

19grains of Win 296 seem to me ...to be a .357 mag load..../ or maybe I'm really confused ...

Sorry, I didn't get really specific, let me clarify.

Yes I'm making .357 S&W magnum loads in .357 brass. I have no idea how or even why this relates to the question though?

I know I can get more velocity from the load but this is a good middle of the road .357 load that I like & it's plenty fast enough to punch a hole in paper.

As far as I can tell the version I have did not have the Teflon coated slider, just a metal-to-metal sliding fit. It was also pushed & pulled manually to dump the charge.

You're right - it doesn't matter....as long as you realize you're well below the published minimum charge for Win 296 as an example ( where min is 21.0grains ) ....but its your gun ...your hands and eyes... / but there might be new reloaders out there reading these threads...and I would never suggest going below published minimum loads...especially when you brought up a powder like H-110...where Hodgdon specifically says do not go more than 3% below the Max ...on H-110 ....

I was just curious in understanding where you were going .../ and if I'm getting into your business I apologize..../ but I still wouldn't go below a minimum charge ...I'd change powders, since you're chainging anyway ...to get where I wanted to go with a published load.

If I were you ...and wanted a load in that velocity ....I'd look at Win 231 powder... but there are other options from the Hodgdon online reloading manual ...that is making Winchester powders now...and here is an excerpt using the bullet you designated....if for some reason you don't have it.

I don't think the Dillon powder measure charge bars are coated in teflon even these days ...but maybe they are. Dillon can certainly tell you. Stay safe !
