Thanks...the Rem. Cylinder is longer, and suspected it has more volume. Is that way with the .36, and as the 44 version is the same length, then was depending on the conterbore's depth.
Know in the .36 Rem., there is a 18% increase in volume...so takes 18% more powder to seat the ball the same distance from the cylinder's end.
Not a recommended loading, and not real useful as those .380" ball don't seem to shoot well at those speeds (and of course, the more powder your burn, the more rapidly fouling builds up).
Just wondering...was shooting a Colt Navy and rem. .36 side by side, and while it's obvious when you look at them, it escaped me until I found that when using the same charges in both was (1) not getting the powder compression I like with a 25gr. charge and (2) when getting the right compression feel on the Rem. (32gr.) was having to over-crunch the Colt.
If I'm lazy, 28gr. works well enough for playing around in both....the Colt just gets a ball over the powder then grease, the Rem. first gets a felt wad under the ball.
