you can use caulk backer rod for a filler. Lowes or Home Depot should have it and it comes a half inch diameter that can be sliced into sections

 

it is for filling large gaps before you caulk   

 

When you use backer rod, how much longer than the space in the case do you cut it to get compression on the BP??

I use APP not real BP but I charge the case, insert the rod and cut it flush with the case mouth with a razor blade.

You might want to check the MSDS on that caulk backer material and make sure it's ok to breathe in vaporized /burned residue of it.

I just googled 3 and found nothing alarming. One said if burning would produce CO & CO2. Is there really a worry about a little chunk clocking a few hundred feet per second downrange outside to be a problem. Never used it, but a lot of folks do.

Hi all,

 Have been shooting 44-40 in BP and was wondering about 45 colt as well in revolvers.  Shot full cases of 3F Goex with 45 colt 235 grain bullets in the past and found it to be too much recoil for me.  Was thinking 200grain bullets this time. Would going to 2F BP make a difference as well? 

I'd like to keep the load around 30 grains or slightly less if possible; any fillers recommended?

(Not interested in any BP subs or short cases like schofields; want to stick with regular 45 colt brass.)

I use a 250gr bullet and whatever 2F BP I have on hand. (currently Schuetzen).  Fill case with powder to allow for a LITTLE compression and then top off with the bullet.  Crimp and your ready to go.
