Good evening gents,
Below the latest target shot with my Greener-Martini 45-70 and a groove diameter PP bullet. After correcting the moving POI issues with this rifle, and in order to test the effectiveness of the correction, some experimenting was called for with a new (read cheaper) polish powder, in theis case Zloty Stok ZS5 (Fg). All shooting at 75m, prone, with 2-point sling, no support. Seems the powder has some potentil, even if it will need some testing at distance to really prove it.
The 1st target below, including the 1st shot from a cold, clean barrel, which printed in the X-ring. Of course, the next 2 shots printed lower, 9's at 6.
After a sight correction, I was able to keep the rest of the shots in the 10-ring - except of course for that single badly pulled shot in the white at 7. The load was 71 grs of powder behind a 30:1 RN bullet, wiping between shots with wet bore pigs, folllowd by dry VFG felts and patch.
The target below was with a slightly heavier load - 73 grs of powder, and even more compression:
The powder is pretty dusty and dull, no shiny granules like swiss. Still, it does seem to have some potential - and is quite a bit cheaper...
