new caliber help

[seahawk]

greetings,
have a new badger .40 and waffling between 40-50 sharps straight and 40-50 sharps bottleneck,...i have .40-65 that shoots great, but like something a little lighter and, i do like the not so common calibers

any suggestion and or recommendations from experience?
thanks

I have no experience to draw on with respect to these two cartridges, but I would always opt for something straight over something bottlenecked, especially if the neck is very significant.

But overall, I would opt for whatever has the most easily sourced brass.

What twist is your .40 barrel (and your .40=65 for that matter)?

brent,
yah, i was thinking about the .40-50 ss,...straights are generally easier to work up a load,..but,.there is something intriguing about the the bottleneck for sure,...im in no hurry so i think ill do some research before i jump in with both feet.
both my barrels are 16 twist

The drawback is the the brass. I tried one with shortened Prvi Partizon 303 British brass and found the neck area for the 40-50 to be way to thick. Never did get the thing to reliably seal the neck and was left with so-so accuracy, ten shot groups usually had 2 or 3 fliers. I heard Winchester 30-40 Krag brass was the way to go but never found any in my area. Good luck to those that have one, I went back to the 40-65 where thin necks are the norm..
