Morning DWB Members:
I am looking for info on a Load for my

I appreciate any help.

Been shooting 80 gr 2F Swiss and a 410 gr NE with a wool wad lately in my Whitetail.

My load is 75 grs Triple 7, 3f, home cut wad, and my 338 gr conical cast by Ed Mehlig.
Fired it 3 times at game, drt each time.
All pass thrus, not recovered one yet.
Estimated velocity is 1500 fps.

~1588 fps for me with the 80 gr 2F Swiss and the 410 NE.

~1565 fps with 80 2F 777 and the 410 NE.

Thanks for posting these.
Do you think my T7 3f estimate of 1500 fps is low, based on your results?

I would say so. A few different conditions for me though, I’m at 7k feet, using 2F, an 410 bullet and a shorter barrel.

Right. I've never had a chrono to clock it, but it kills like a .416 Rigby...lol

Those are very impressive numbers; approximately 2230 and 2296 FPE from 80 grns of powder. That's 27.9 and 28.7 FPE per grn of powder.

Compare that to my 58 TC which pushes 560 grns at 1350 fps for 2290 FPE with 120 grns of 2fg or RS = 19 FPE per grn. I know Swiss and T7 are more energetic powders but not 50% more energy per grn.

Apparently, to make a lot of power with BP we need to put a lot of weight in front of it in a smaller bore. Doc knew what he was doing.

Yes, quite a difference in the powder to velocity/pressure with the smaller (.40 and .45s) compared to the larger bores (.58).
