Gallery loads for .45Colt

[Pulp]

A feller CAS member asked me to chronograph some very light BP loads in .45Colt. I loaded 5 shells with 10 grains of Goex FFFg, topped the case off with cornmeal, then seated a 140 grain roundball and fired them through my Walker with R&D conversion cylinder. For comparison I also chronographed 5 loads with a 250 grain bullet over 1.9cc of 777 FFg.

I was kinda surprised to see flame from the light BP load.

What were your velocities?

What were your velocities?

The RB loads averaged 521fps with a 12fps spread. The 777 loads averaged 923fps with a 25fps spread.

I also learned from watching the video, I need to get consistent with where I put my left thumb. Where I had it part of the time is not a good place when shooting semi-autos.

Good observation, your thumb will thank you

The 45 auto takes a different discipline than that SA revolver, I always point my thumbs along side of both auto and revolver.

I've been bit by a Colt Woodsman. Sliced my thumb pretty deep, but no stitches required.

Nice vid, what did you video the shots with?

 

[Pulp]

IKam glasses. They are great for handguns, not so hot for rifle/shotgun.

I don't have ANY experience with black powder, but is there any risk of secondary explosion effect with light loaded black powder rounds?

As long as there is no air space between powder and bullet it's ok. After pouring powder I fill the case with cornmeal, then seat the bullet.
