Las sunday I shot my BSA 12/15 rebarreled to 32-20 and converted to CF at 200m, 1st try with PP bullets.
Those that have been following my experiments, know that the little rifle sports a 1:15" twist barrel, so allows the use of heavier bullets - in this case a 150gr PP bullet
The remington case was loaded with 17.4 grqins of 1 1/2 Swiss, with an overpowder card wad, the .301 bullet patched with 8 lbs paper seated on top in fireformed cases.
Primer was the federal small pistol, and the bullet was seated out in order to be hard into the lands when the breechblock is closed.
For a 1st try, the results were very encourqging, as illustrated by the target below - remember, prone, sling only, no support and aperture sights:

I was pretty pleassed for a 1st try - for reference, the 10-ring is 2 MOA, the 9 4 MOA.
One thing that kinda surprised me was the BC of my bullet - looking at the elevation difference between 100 and 200, it would be about 0.45, which is quite bit better than I had assumed when designing the bullet.
