WST (Winchester Super Target) PUBLISHED load data for 9mm

[forrest r]

I keep seeing compressed loads are a bad thing in this thread???? Myself I want 100% fill and better yet a compressed load if possible.

Here's what Hodgdon has to say about compressed loads.
Normally a pistol or rifle shellcase is considered full, or 100% loading density, when the powder charge sits at the base of the bullet when the bullet is fully seated. It is possible with some powders and cartridges to increase the powder charge slightly above this point, such that when the bullet is seated it actually compresses the powder charge slightly. This condition is known as a compressed load.

Hodgdon notes in its reloading data if the subject charge is a compressed load. A full case, or lightly compressed charge is an ideal condition for creating loads with the most uniform velocities and pressures, and oftentimes, producing top accuracy.

Depends on the powder. Plus pistol powders are much more energetic than rifle powders. Many rifle powders do well compressed. Pistol powders not so much. Generally speaking.

Interesting I use a lot of bulky powders and never had any issues other then extreme accuracy with a bunch of different powder/compressed loads.

I've used compressed loads with:
redot
greendot
american select
clays
international clays
unique
power pistol
wst
h110
ww296
4227
Just to name a few.

I just came back from the range after testing new loads for.40S&W and was shocked that Unique performed in the bottom. I had no FTF/FTE problem-they all went bang and cycled the action- but accuracy was awful and they just weren’t getting the speed of other powders. But I used published data and stayed well inside the lines.

My best loads with Unique, in most cases, are near the top of it's loading data. My standard .45ACP 230grn load, as an example, IS the max data... but it works very, very well there. Other cartridges I've used Unique in at or near max are .41MAG, .45 Colt, .380ACP (believe it or not...) and even 9mm (which you have to pay particular attention to the bullet seat depth, as I have stated previously, if you are nearing max published.) For that matter, I have found WST to work the best near the top of it's data... 200grn .45ACP, for example. WST still didn't produce top velocity, but they were very accurate and cycled 100% I have 0 experience loading .40S&W, so I can't suggest anything one way or t'other, but my first thought is if there is still room in the data with Unique, I would bump it up.

I loaded 5.3, 5.5, and 5.7gr in Unique. 5.8gr is max according Lymans 48th. All of the loads tested ran the gun and most went in the black of a 25yd slow fire target; but Unique had the widest spread low-to-high and the largest groups overall. I was surprised by that considering how well it performs usually. But that’s why I try a variety of powders. I didn’t even bother testing TiteGroup or Bullseye given the negative feedback of experienced .40 hand-loaders. Maybe it is just the XDm.

Off Topic...
"LiveLife" who started this thread and has over 25,000 posts, hasn't been heard of in more than 5 months.
I'm hoping all is well whatever the reason may be.

I was thinking the same thing today

OK, so I shot 40 rounds of the 4.0 grain WST 124 gr. Hornady RN FMJ loaded to an OAL of 1.15. In my Star Super B they cycled perfectly and in my Star BM which is more highly sprung I had two stove pipes at the very start and after that all cycled well. It felt quite "snappy" for a light load. Accuracy in both pistols was superb, all rounds clustering together. I think this merits a step up to 4.1 grains but I think I am quite close to what would be the optimum target load. I'll report back once I do a little more testing.

Just because it did not function one gun, doesn’t mean the pressure isn’t up, be careful.
