I loaded 'er up today with some RCBS 45-270SAA bullets over 8.0 grains of Unique. The book says that should go 924fps. I was shooting at a paper plate taped to a much larger box set up at 21 feet. Holding the top of the blade straight across the sights, it shot about a foot low. But using half a blade up over the sight, I pulled it up onto the plate and could keep each cylinder on the plate using that sighting. I didn't get any great groups, other than keeping each volley of 5 on the plate, but it was fun. (I only load 5 in a gun with no safety)
The small grip isn't much good for drawing, at least not from the holster I was using. I'd need to select one that lets it ride up high so I could get 3 fingers on the grip.
But it was very comfortable when sighting, both with single and double hand grips. I mostly used one hand and it did provided quite a bit of flip up when fired, but not unmanageable and nowhere near enough influence a fairly quick sight recovery following the shot.
I'm pretty impressed with it thus far and will try to load some 200grainers and see if I can get them hitting a little higher. I do like the 45-270SAA bullets a LOT though, so in the long term I might end up lowering that blade just for those.
