Thanks for the link. I may dig out my POS Chrony & check my current load - 100 volume equivalent of BH 209 (74 grains weighed) and see what velocity I’m getting with the Federal Bor Lock bullets.
What weight Bor-locks? I actually have some and some 209, I could put it over my Magnetospeed if it helps you.

Can you shoot blackpowder/blackpowder substitute over a Magnetospeed? I would be afraid all the particulates and nastiness would ruin the sensor.

They’re 50 cal, I think 275 or 295. They only make the 1. BH209, 74 grains weighed = 100 grains by volume.

I still have no reply from Western Powders.

Thank you!
Ok, finally got out there today, sorry for the delay. I had two different Bor-Locks on hand. The 270gr all copper and the 350 lead. Since you said 270ish I just went with those. I scaled out the 209 at 74 grains and shot three over the Magnetospeed. Ended up with a 1715fps average here at 5000 feet at around 42 degrees. Hopefully this helps, let me know if you need any other info.

I forgot to mention that the T/C will take a lot more 209, I think it will still pick up a bunch of velocity closer to magnum loads.
