which cylinder chamfering tool do I need?

Lou_NC · Jun 5, 2020

Finally going to treat myself to a cylinder chamfering tool from Brownells so I can break the sharp edges of my model 625 .45ACP chamber mouths. In browsing the list, I see THREE choices, all of which state "fits .45 cylinder". Two of them say they fit .45ACP cylinders. Here are the numbers:

080-948-456WB - fits ".45ACP-2 cylinder"
080-948-448WB - fits ".45ACP-1 cylinder"
080-948-451WB - fits ".45 cylinder"

The 625's I plan to work on are a combination of -2, -3, -4, and -8. I may also chamfer a model 22-4.

Which item do I need, and what are the differences, especially between the one that fits .45ACP-1 cylinder, and .45ACP-2 cylinder?

Thanks,
Lou

Frankly, I can't imagine. But someone here may know.

But to get the info straight from the horse's mouth, I'd call Brownells and ask to speak to their Tech guy.

I bought the #080-942-448WB, 45ACP-1 pilot. Can't remember why I settled on it.

It fits my 325NG, 325TR, & PC 625-8.

Read Brownell's QA/Reviews (for the pilot only) to decide for yours.

If it's too tight on one of yours do that one last after reducing the pilot's diameter in a drill with some fine sandpaper.

.
The dimensions I wrote on the bag are for the throat (Muzzle) & chamber (Breech) ends of the pilot.

I would never chamber the ejector star on a 45 colt. 45 Colt has the same rim OD as 44 special/mag. This makes the rim ledge real small. Don't take much to slip ejector star by as it is.

Now on a 45 ACP you can have at it. The star and arms are almost completely covered by a full moon and they hit a big piece on 1/2 moons. Plus, ACP brass is made heavy near the case head because most semi auto chambers have a feed ramp that leaves the brass unsupported in this area.

Thanks Bluedot, that's exactly the kind of help I was looking for, especially posting the packages so I could read the Brownells part numbers off the bags for the pilots! I'll give Brownells a call as well.

Did you lap after cutting the bevel? I hadn't thought about doing that. Did the cutter leave a smooth enough finish, if I decide not to lap?

Thanks,
Lou

I bought pilots for several cartridges as well as other chamfering tools. That 45° lapping tool was only used when I chamfered the muzzle/crowns.

It's a little touchy chamfering the charge holes especially if you remove the extractor/ratchet, which I prefer to do.

It cut fairly smoothly though you can see a little wave in it but not enough to prompt me to lap it.

Just try to be firm & smooth. Once you start to get chatter it's hard to stop it. The lap is worth having on-hand.

My picture shows 320 grit but I mainly use their 600 grit abrasive compound.
