First thing you need to do is have the cylinder throats opened up to at least groove dia. or maybe .001 over, you'll never have good accuracy with it setup like it is.
You also need to check for bore restriction at the barrel/frame junction, if there's a restriction then it needs to be lapped...
Remove the handle and replace it with an allen head screw then use a straight "ball end" allen wrench chucked in a V speed drill.
Mount the trimmer on a piece of 1X4 so it can be clamped to a work bench.
The lube on cast bullets is a must to help prevent leading of the barrel.
The lube does two things, 1 it lubercates the barrel to reduce friction and prevent leading 2 along with bullet base orbatition it acts a gas seal to prevent gas gutting and leaves a layer of lube for the next shot
Unlubed...
Barrel groove dia. should be .312 on both, you need to slug them to find out.
If groove dia's are right then I would have the throats opened to .314 and shoot the .313 or even .314 dia. cast
You must remember that Bluedot is tempture sensitive, it can build excessive pressure in temps below 40°.
So if your are building near max loads in summer temps they may show excessive pressure in the winter.
I like BD but don't use it when temps are going to be below 40°
"I had a bit of a problem with consistency with all these cast loads. I think it might stem from the crimping. Somehow, cast boolits seem to seat less precisely than jacketed bullets. So I messed around a bit to get the crimp consistent, and the rounds that weren’t consistent are probably at...
Just about any 250/260 cast boolit and 4.5 Red Dot is a prety good load.
My wife shoots this load in a Uberti Thunderer with 3.5 in barrel, off hand in CAS matches.
Any ACP bullet can be used in the 45C, the problem is bullet dia., most ACP'a use .451-.452 whereas the 45C usualy requires ..453-.454.
Slugging the cylinder throats/barrels will tell which dia is needed.
As far as style is conserned a 230gr rnfp will work in all fairly well.
By the way, what's...
The first thing you need to do is slug the throats on that RH to see what size they are, chances are they will be under .452. Slug the bore while you are at it.
Bore and throat dia. need to be equal or the throats .001-.002 bigger than bore.
If the throats are smaller than the bore, you will...
