Sent Tom Armbrust a test set-
10 gauge 2-7/8" Federal hull FED209A 31.6 gr Longshot PT1044 (no fillers) 1-3/8 oz. (600 gr) ITX10-2 Will report pressure results ASAP. 1,343 fps variation 32 fps 8,780 avg psi variation 2,100 psi (high 10,000, low 7900) Last edited by James Halvorson; 10-17-2018 at 10:31 AM.. Reason: Pressure results. |

Not a 10 gauge load, but a lower pressure 12 ga, 3 inch, bismuth load I have been working up for one of my British waterfowl guns. Might help as a starting point for someone.

Pressure variations came back high for the old gun. See edited post above. Will update with sheets when they arrive in the mailbox.
Note that average pressure and velocity is almost a duplicate of the Nice Shot load that this is based on. |

If you were able to roll crimp that load, you might make it there.

Big pressure variance in my opinion. I would not be satisfied with that load if u plan to use it in a vintage double.

That is some interesting data. Very low(in my experience) shot-shot velocity variation, and yet fairly high pressure variation, ie 2% on the velocity and 24% on the pressure. Shotguns seem to play by their own rules. I wonder what could explain this?
