For what it's worth, I found that using a faster powder (Vectan AS, similar to Red-/Green Dot) made crimping quality (or the lack of it) much less of an issue. More reliable ignition and uniform velocity compared to the slower powders. Also, an x12X seal over the powder works wonders on ignition, but you probably knew that already.

Yes the x12x is the perfect seal - Zero blowby. I do have 800x, Longshot, Green Dot. Gotta do some homework though. I am inclined toward 800x as I got good results with the full bore "zlugs" with that powder.

105yds! Thats fantastic.
(and serves to remind me every time I see this post updated that i have been lax (*) about testing mine).
(*) not lax, really, just busy. But I still feel guilty. it'll happen though!

HT,
Nice work! I have the same roll crimp trouble, I need to invest in a real shell vise to improve my roll crimps.

HT, in a word, WOW.
HT. Nice.. Seems stiff wad column and good crimp are the ticket...which I am finding is true for many of different slugs I have been firing. Including the zlug. I'm really liking lil gun with these slugs. I believe it's real close to steel on burn rate chart. Will have a nice hollow point model of this slug soon. Still testing. Turn some of that penetration energy into expansion. D
I think all this slug testing is causing earthquakes on the other side of the world! I look at that picture and feel pretty good, except 2 of 6 missed a 2' x 2' box. Now I have been known to flinch a little from time to time but not quite that much. Wish the trigger was a little lighter on that USH too. BTW, the good advice I got here regarding the light primer strikes cured that problem. A little light work on the hammer with a file was magic. Thanks to all.

HT,
These directions will help you get the trigger you want on your USH. If you do a trigger job replace the hammer spring with a Wolff extra power hammer spring. These are good instructions and you will need to make and use the slave pin unless you want to drive yourself nuts trying to put the internals back in the right spots.
