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 8)

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. :-\
