Cutting 475 to 480

[ridenshoot]

"That sucks, so you happen to remember the seller?"

The seller of the jig I bought was Proczak.  In fairness to the seller, they did refund my money for the broken jig, but what I really wanted was one that worked correctly.  It seems like it would be rather easy to make one but it wasn't worth the pita to bother with getting another one since the packaging was so poor, and I had little hope that they would correct the design to fit the saw.

Well I THINK this is who I ordered my one jig from. They DON'T sell a 480/475 one, but it might be worth reaching out to them to start.

But since the parent case is so short, I can see it presenting problems in operation, holding it in place while keeping your fingers out of harm's way.

Not to worry, while using the HF saw to cut down .475's the left hand is nowhere near the cutting blade.

Thanks Sir!
Good to know, I can excuse poor packaging as long as they learn and replace what is lost but if the design is flawed that’s not encouraging.

This is good to know thanks! I thought this is the seller who is working on a 460sw jig for me to try, and I was going to get the 500 max jig from them. But the seller I was thinking of is reloading3D. Maybe I’ll order one from each to compare, though as Gnappi shows I guess they aren’t necessary. I do like gadgets though!

This is a completely different design from the one that I purchased.  The one that I purchased was oriented from the other side and was meant to screw into the holes on the right side of the base, but when it was aligned with those holes the saw blade barely touched the brass.  I like this design, may contact them to see if they can make a 475 to 480, it would be nice not to have to complete the trimming with my RCBS.  Thanks for sharing!

I attempted to use the .475 to .480 jig from Ebay and found that it was not sized properly.  It was poorly packaged and was broken when I received it, had it not been broken it still would not have worked.  When screwed into the holes as depicted the brass was not aligned properly.  I messed with it hoping to find a way to make it work, in the end I gave up and kind of went the route that gnappi came up with.  I cut the brass a little long, then finish it up with my RCBS trim pro II, has been working fine so far, I've done around 50 pieces of brass.

Probably should wash my hands before picture time.
.475LB cut to .480 length

Is it me, or does it look like those bullet holes show some keyholing?

I have made many home made jigs from stacks of washers, steel bushings etc, to cut mass quantities of brass down for lots of different cartridges, then it’s just inside and outside ream the case mouth. I use a thin cut off when on a 4.5” grinder. Insert long case, trim off brass ring ( grinder cuts in a second) throw in a pile to finish off.

Are the 475 -> 480 trim going to require an inside reaming?

  Not on any I trimmed with the 325 grain bullets that I cast. 

[bearskinner]

Agree, it would have to be a huge or extra long bullet to go deep enough. Then you wouldn’t have enough powder to move it.
As it’s ugly and snowy out, I might just go thru my 45-70 brass, cut down one of each brand and play with a few, in my custom, Reeder built Ruger 5 shot Blackhawk. Just to see what differences there is in various 45-70 cases cut down. I want to trim some for the new 475MAXIMUM too

[bigbore5]

I load a 415gr swc without reaming in cut down brass.

[lockhart]

I wonder why RCBS, Lyman, or one of the other big reloading companies
haven't come out with a 480 Ruger trim die? You know, the one you put
in a single stage reloader and just trim the 475 Linebaugh cases to
480 Ruger length? This ain't rocket science!  Instead, I'm stuck with a big
revolver that I can't get cases for!  Just wondering--------

[gnappi]

You can get .475's they're not a chore to cut.

[lar4570]

I remember way back when... Mr Linebaugh said to use Winchester 45-70 brass so you wouldn't have to inside ream when making 475 Linebaugh.
I never tried anything other than Winchester brass so I don't know if any other brands are thicker.
