Today is Thursday and yes, I went to the range to test my new 1858 Navy brasser.
Using a two hand hold, at 10 yrds, I got a 3 inch grouping, 3 inches to the right and 6 inches low. Now to file gradually and carefully the front sight until it hits bulls eye. For windage I'll have to tap the front sight to the right a miniscule amount.
I used about 36 cartridges I had made, with 15 gr of FFF. Because the frame is the same as the .44 Army, the ram, that was originally a .44 ram, is reduced at the tip to .33" for only .42", and using only 15 gr of BP plus a wax/crisco, the travel of the ram is marginal on pushing the ball all the way down. Later on, I loaded 18 gr and that gave enough fill in the chambers to counter the limitation of the ram.
Am I happy with it? yes and no. Because it is a .44 Army frame, the Navy weighs (2lbs 13oz), more than my .44 Army (2lbs 11 oz). That's a bummer. I think I'll have to get the Colt 1851 Navy, that I presume weighs less (If somebody may provide the answer, I would appreciate it).
On the positive side, it is a precise shooter. I just have to make it accurate too.
It is a keeper.
Now comes the task of washing it
By the way, I pushed in a ball into one of the chambers, and then pushed it out an gave me a diameter of .3670". (I'll have to get a set of internal diameter gauges for the future).
