Howdy again from snowy Kachemak Bay .
I managed to try a few 38 WCF loads yesterday. I forgot to take my snow-shoes with me so I only made it about 52 yards before my pounding chest said it was a good place for the target board.
From my old 1892 WIn, 24 inch lightly pitted bore. Tang peep
Star-line brass, old CCI-300 primers
1.587 col, roll crimp, Magma .403 sized
Temp 11 F, light wind
10 shots each with cleaning every 5 shot.
8.0 gr IMR-800x,,,, = 1,228 fps and a 2.6 inch group
6.8gr HP-38,,,,,,,,,, = 1,134 fps and a 3.2 inch group
6.9gr HP-38,,,,,,,,,, = 1,158 fps and a 3.0 inch group
8.0gr Herco (old),,, = 1,165 fps and a 3.5 inch vert string group
8.0gr Universal,,,,, = 1,170 fps and a 3.2 inch vert string group
8.0gr Unique (old) = 1,182 fps and a 2.9 inch group
33.0gr Goex 3F,,,, = 1,075 fps and 20.0 inch group * CCI Mag primer, lubed with wonder lube
29.0gr Goex Clear Shot= 960 fps and a huge group. *CCI mag primer, very dirty.
So at least I am on paper, (compared to my last post with undersized bullets) but this old gal has not shot very well ever since I cleaned all the old lead from the barrel pits. Plus I ran out of the old semi-hollow based bullets that I bought from Fuller in Cooper Landing 30 years ago. Back when I could see better as well.
I also noted that my velocities went up and are much more consistent with the .403 diameter slugs. Except for the black powder and Goex Clear Shot loads. Those are slower and the velocities are all over the place.
