John, I'm with ya, and thank you for the input. One thing
I noticed with Universal early on was unburnt powder
present if the load was below 10% of top. In cases like
the .38Spl it was very light or even a trace amount seen.
I suppose the smaller case allowed better combustion. But
with the 45 Colt mild and moderate loading will leave
powder in the bore and cases.

I loaded some .44Spl and .44Mag cases last night during
the rain in hopes I could test them today in my Bounty
Hunter single action. Both were loaded within a couple
tenths of a grain of top load for "Cowboy Loads"
respectively. The bullet is the 240gr Berry's copper
plated FP. The mag load is almost identical to the 45
Colt load for a 250gr, but there's less of an air gap
present obviously due to the smaller case. Will be
interesting to see how they do. Seating depth was by the
book. I'll know in a few hours after the sun's up and
things dry a bit on my range.

Wasn't bad in a 44Spl case but in the mag case, if I
tapped the weapon muzzle up I got a healthy boom. Tapping
muzzle down it didn't pop, but felt a bit more mild. Had
a flatter report though. But not as pronounced as in a 45
Colt case that's for sure. In both the special and magnum
shooting the POI remained the same.

Lessons Learned: Universal is good powder and lends
itself towards accuracy in several calibers. However, it
can demonstrate a tendency of position sensitivity that
is enough to hinder repeatable speed and impact upon the
target.

Conclusion: Load close as possible to top loads within
safe limits, and avoid lighter loads all
together. Further, seating depth has proven critical as
well in obtaining positive and consistent results.
Heavier, longer bullets, are the preferred projectiles
with this powder.

Overall, not a bad powder in that it doesn't display any
tendency for detonation, nor any safety concerns. It
does, by its past performance with my weapons,
demonstrate the need to elevate its loading close to 100%
max, and no lower than 95% in order to perform well.
Definitely not a beginner's powder, and should be
utilized by a veteran loader.

I'm down with your conclusions wade... did
some powder position sensitivity tests with
light loads on 45-70 and 06 a while back...
loading about 25 grains of Lil Gun or blue
dot in either they both went from healthy
bang after tilting up to fizzly pop not quite
a squib after tilting down... used the dacron
pillow fill trick and solved the problem...
but man is that tedious...
