  Where is Yondering or one of the other handloaders? I would love to see someone playing around with the Ramshot so we can compare.

The load data for silhouette leaves velocity lacking about 200 fps when you hit a max load. It would be ok for mid-range loads, but not if you really want to maximize performance.

The two I have tested are close to the top in 10mm.

Yes, but they are well off book in terms of load data.  So, unless you have several thousand $'s worth of pressure equipment laying around, you are building loads that are potentially unsafe.

 Those black rounds are cool

That's what makes the ID of the powder such a challenge, because the data is not normal ranges.  However it did fit other powder profiles like AA#5.  IC spoke with the people and was told that is what they used.  The projectile is lighter than advertised, is coated also, so that may play into the achievable results to a point.  Once I get some of these powders in my inventory to play with I will learn even more.
