Hello all,

I was wondering if anyone out there had used this .357 load from Alliant:

7 grains of Green Dot over a Fed 200 primer, 158 gr. JHP.

The reason I ask is that I also shoot a lot of trap, and at the moment I am out of 231 and 2400, but I have about 12 lbs of Green Dot on the bench. If so:

---What is your accuracy like? (5 inch 627 PC will be throwing the lead here)
---How dirty is it in handguns? (I've never used it in a revo. before--as you know it's dirty, dirty stuff in a shotgun)
---Do you get the advertised 1215 FPS?
---Give me your thoughts on this load overall

This one interests me because I, like most people here, would like to do some consolidation of powders and at 7 grains, I could probably get close to the 1000 round mark out of a pound if I'm dropping accurately. Thanks in advance for your responses

One of the problems in buying powder from estate sales is that you end up with some powders that you would not normally use. My acquisition of Green Dot falls into this category.

So I gave it a test in 357 and in my 38 Spl Airweight.

Now you are looking for 357 data and I have only one data point. But it is close to yours. What I can say is that it shot well.

It was inferior to Bullseye with 125 LRN in my snubbie. Bullsye shot tight circles inside of Green Dot at 25 yards. Green Dot shot well with 125 JHP in the snubbie.

Green Dot is kinda of a between powder. It is not as fast or as good as Bullseye in light loads, it is not as slow or as flexible as Unique. I am not a clean freak, if it does not foul the extractor star, and hits in the middle, then I don't care.

If you have it, well use it. Take a chronograph and develop some loads, you should be able to get an acceptable 1000 fps load with Green Dot. If you want 1200 fps, go buy some 2400.

Thanks for the info and going to the work of posting it. I kind of figured that it wasn't going to be spectacular, and I think I might try it just to see. I have so much of it for shotgun use, and we all know what lead shot prices are doing! If I do, I'll be sure to post my results.
