Hello,
I currently use WST for .45. I am about to start reloading for 10mm. I have some 180 SWC lead bullets from Precision.
Is there a load for the WST? It seams the winchester info is harder to find than most.
Is there a better powder for use with both or should I get seperate powders.
Thanks

I used my 5.3gr 45/W231 load for some 180gr bullets, and it averaged 950fps out of my 6" barrel. W231 is slightly slower burning than WST, and it gets a little more velocity in 45. If you want to use WST, just work up from Hodgdon's .40S&W data (I believe 5.7gr is MAX for .40) The 10mm is a different animal, and performs better with slower powders. It all depends on what kind of load you want. Power Pistol & Unique are a couple more suitable powders for both calibers, but there isn't really ONE powder that's optimum for both 45 & 10mm.

What are you using each load for?

Sorry about nothing on WST, but the 6th Edition Hornady reloading manual shows data for 10mm Auto with a 180gr SWC, so I figured I could at least throw a few ideas your way.

Hornady used a Winchester LP primer with a COL of 1.260". Velocity testing was done with a 5" barreled Colt Delta Elite. That said...

Alliant Bullseye
4.2gr = 800fps
5.0gr = 900fps
5.8gr = 1000fps

Accurate Nitro 100
4.5gr = 800fps
5.1gr = 900fps
5.7gr = 1000fps

Alliant American Select
4.4gr = 800fps
5.4gr = 900fps
6.4gr = 1000fps

Alliant Unique
4.5gr = 800fps
5.5gr = 900fps
6.6gr = 1000fps

Winchester 231
4.7gr = 800fps
5.5gr = 900fps
6.2gr = 1000fps


Those were all the powders Hornady tested with that reached 1000fps. They did NOT show any loads above 1000fps. Three powders were tested that "only" reached 950fps, which were: Titegroup, 700X, and, N-340. But those three powders used within 1gr powder of the rest so why bother with them in the 10mm if they aren't as efficient or whatever.

Hope that gives you some direction if you don't come up with any other information. BTW, Hornady used their own cases for testing if you want to know.


Good Shooting,
Craig

Forgot to ask in my first post......What gun will you be shooting them from?

Thanks for the help so far. I have a G20sf. I plan to use most of these 180 for practice but I would like to make up some faster ones for hogs. There are some on my property in OK.
I was hoping to use the same powder just to make it easy. I might try to work up from the .40. Is there a recommended powder for for full power 10's or just any slow burning one?

Be careful getting loading data from forums!


After some testing I have gone to IMR 800-X for all 10mm loads.
I use 8.5gr of 800-X under 175gr Magnus SWC, Starline brass, CCI #300 LPP.
A very good power and accuracy round, not max.
IMR 800-X is not the easiest to measure but I have found I get a good powder drops with my procedure.

Are the 180 SWC lead bullets from Precision hard cast? You didn't mention if you're using an aftermarket barrel or not, but lead bullets aren't really supposed to be being run through a stock glock barrel. Heavy barrel leading can occure with the polygonal rifling glock uses in glock barrels, which can lead to dangerously high pressures from the lead build up, shot after shot.

Besides that, if you really want some half way decent powered loads with any 180gr in the 10mm, lead or jacketed, you aren't going to get them with the WST powder you originally mentioned. It's much too fast burning of a powder. In 10mm, you could get away with WST for plinking loads, sort of like the data I posted earlier, but nothing even close to the velocity levels you're looking for.

Can you explain further if you are or aren't using an aftermarket barrel with conventional rifling, and if the said bullet from Precision is HardCast or not? From there we could probably help you further.

I have a Lone Wolf barrel. I think the Precisions and hard cast. I will look later.
I will probably just pick up a different powder at some point.
Thanks for all the help so far.

At the following link, are these the bullets you're asking about?

http://www.precisionbullets.com/

If so, on the products page, in .400 caliber, they list a 185gr RNF. They do not list a 180gr SWC. Are the 185gr RNF what you actually have?

It also appears they use a proprietary solid dry film lubricant. Is that coating on your bullets?

You are right. I guess memory is the first to go. I just looked and they are 185 rnf. They are hard swaged and coated.
I plan to get a Lyman manual. Does it talk about coated lead bullets?
Thanks,
Chip

I'm not familar with the Lyman manual. But one thing I found out is that you can push those Precision bullets that have the proprietary solid dry film lubricant up to 2000fps without leading problems. Obiously you aren't going to get anywhere near 2000fps, just saying that under 2000fps Precision claims no barrel leading below that number.

Anyway, now that all the cards are on the table so to speak, and you're looking to build up a high velocity hunting load, maybe someone out there can help further. And I think you know by now that it isn't going to happen with WST.

Most of your best bets with powders are probably going to include:
Blue Dot
800X
AA #7
Longshot
plus more, but I have no idea whatsoever what a good starting point is for the bullet you're going to use in conjunction with any of those powders.

Hopefully someone out there can help you further with a starting point.


Good Luck,
Craig :thumbsup:
