450/400,

If you're doing the work yourself, I suggest that you check the dimensions of the 375 flanged case against the 375 belted if they are close enough, sorry I don't have any thing with the flanged dimensions, you MAY, repeat MAY be able to use the belted reamer to run the chamber in stopping at the right point and then finishing the rim recess with a separate cutter. The rim cutter would be easy to make if you have or have access to a lathe and mill.

I use the above procedure on some belted magnum chambers in order to get the case to headspace on the shoulder rather than the belt.

Hope this is helpful.

That sounds like more work than is necessary when I can buy a new, correctly dimensioned reamer. I just thought somebody might have one they weren't using.

You might call one of the reamer manufacturers and discuss it with them. (I've done it before but I cannot remember who I talked to.)

If you have the drawings, a good reamer maker can grind you a reamer for just about any cartridge.

Thanks for the offers, but proper reamers are available. I just wanted to check and see if anybody had one they weren't using...

Try Shawnee reamer rentals. Do a search for reamer rental.

Did anyone ever find a source for a rental on this reamer? Mike

As pointed out, a reamer is a minor problem. If it wuz me I'd be A LOT more concerned about the brass. IMO Bertram is junk, I've used it or rather tried to use it for a number of applications without much success. Too much case loss due to visible brass defects, which gives me zero confidence in the remaining cases that look good on the outside. Plus the outside dimensions varied quite a bit, enough so that some case rims would not enter the shellholder. Altogether a total turnoff.
Regards, Joe

I have some Bell brass which I have been told is better than Bertram. For a one-off, reamer rental is cheaper than buying if available. If not, it's just money right?
