If the throat is as small as you say then you will lead that sucker like a sumnabeetch.
A .452 bullet thru a .451 throat will strip lead badly. That lead will be blown into the forcing cone and get ironed into the bore.

Very nice just like mine.
Mine is tight on the throats too.
I size to .451 and it shoots accurate and clean no leading in the acp cylinder.
Have not worked out the colt cylinder yet the acp is just so much fun to shoot :)

I have had my best luck with round flat point designs so far.
The SWC designs hang up as you load them on the mouth of the throat.
The round flats self centered and drop in like grain thru a goose!

That's what I was wondering. The lower loop doesn't look like it would work for cross draw, or be aligned for a very wide belt. I like that style holster when riding a snowmobile, to keep the rig from hitting the seat while sitting.

Think I figured it out. You reverse the holster for cross draw. Looks like the muzzle would fit either way. Gonna have to check that out for a 4 5/8" single six in .32 mag.

So the dummy round I made up was with the Lee 300 grain round nose flat point mold. I just went out to the shop and grabbed one of the RCBS 270 single action Army loads size to .452 inches and that chambered just fine. I will probably go ahead and shoot these and see how they work.

Brad is correct assuming your throat measurements are that accurate. You said it chambers fine but take one of the .452" sized bullets and see if it will slip through each throat. If they do odds are your throat measurements are slightly off and/or the bullet is a tad under .452" or a bit of each. Just because you sized them with a die marked .452" does not mean they are.

The idea being that they chamber so if a bullet used as a pin gauge will slip through the throats it won't lead. With the RCBS 45 270 when loaded and chambered the front driving band will already be in the throat so the leading (front) edge won't shave on the start of the throat.

My convertible was the same as yours. I opened throats to .452 but did shoot the acp first without reaming with 230 ball ammo. Ragged hole groups. Didn’t attempt any cast because I knew that wouldn’t work. You just as well order a .452 throat reamer as you will now want more 45’s. Give me a shout if you need or want to try other bullets. Nice Bisley by the way!

You will be happy with that Holster. Rob makes fantastic leather goods, and I own at least a half dozen of his holsters, as well as mag pouches and slings.

Check the front sight on that gun for center. Ruger seems to be having a problem lately with the front sights being canted one side of the other, bad enough that there is not enough adjustment in the rear sight to make up for it. friend of mine just had to send a 7.5" back twice, and they never did get it right.

I went ahead and ordered a Lee .451” size die. Should be here Friday. I’ll give that a try and go from there.

Better check that Lee die with your mic.
May be .451" , may not be ?

A very nice looking revolver Waco.

So the ACP cylinder will take a .451" pin with light finger pressure. The Colt cylinder is a different story. Two of the cylinders will take the .451" pin with light finger pressure. One will take it with moderate pressure, and the other three will only accept a .450" pin.
I guess I'll see how it shoots with .451" bullets before I do anything.
PS, My .451" pin mics out at .4508"

I should've bought a set, when Enco had them for $50. That not being the case, I was later able to find a Chinese cloned inside micrometer that's good enough for my purposes.

If a pin gauge stops just short of the forcing cone it can be a sign of thread choke.

In the end the bore with a pin gauge doesn’t really mean much. We want to know the diameter of the grooves, not the lands. This is why we slug the bore!

Shopt some .451 bullets thru that 45 ACP cylinder and see what she does.
