Anybody have a suggestion of who's capable of cutting me a .458Win Mag chamber but throated like the SAAMI spec Lott?

If it's a double rifle, then it has to be JJ Perrodeau. Not sure if it is a bolt gun.

Thanks for the suggestion MD. George responded immediately to my inquiry, indicating that they're fully capable of doing the work but... that they're also backed up with enough double gun work that it would be unfair to take on this project.

Maybe I can talk my 'smith into running a Lott reamer 0.03" short and cutting the belt recess with a boring bar?!?

It would be more practical to cut the chamber with the 458 reamer and then throat it with a .458 throating reamer.

Jim is absolutely right!-Rob

Just leave it at .458 Winchester. With equal pressures, you only get 70 fps more from the Lott. You can easily handload the .458 Win to 2200 fps with 500 grain bullets and AA2230. Better yet, use 450 grain flat point solids from G.S., North Fork, or CEB and you'll get 2250 fps, a lot less recoil, and MORE penetration than with a 500 grain that uses the classic Kynoch round nose. Been there and done that.

With today's components, there's no reason to fool with a .458 Lott.

A long throat .458 win mag will allow you to load bullets out .25 inches. Use a Corbin Cannelure tool to make a new cannelure on your bullet. You can easily duplicate .458 Lott performance with this set up. I have one done like this in a Ruger No. 1 and it works great!-Rob

You ARE talking about a DOUBLE rifle, right?

Thanks for the suggestions but they're not to the point. No worries, I did not provide much detail however, I'm not trying to make the WinMag into a Lott.

What I'm looking for is a .45 caliber rifle that's very friendly to cast bullets without some strangely exotic setup: the bolt action .45-70 concept if you will.

Hence, I'm looking at a .458WM chamber, a Lott-esque throat, and barrel with a 1-18 or 1-20 8groove twist.

This will allow the use of standard dies and brass and should (based on my experience with one .450Ackley, two Lotts, and this current WinMag) not only accomodate cast slugs much better than a SAAMI throated .458Win, a 1-10 twist .450, and the unneeded capacity of the 2.800" Lott but should still function well with 300-400grain jacketed/mono bullets for N.American use.

So far, no one except mdsteward has suggested who has the capacity to chamber a .458WinMag with a smaller throat. JGS lists a reamer for the ".458WinMagJGS" specifically designed (by Keith Francis) with a smaller throat that still accommodates factory loads. I have not yet gotten the exact specs. but will give them a call this week...

You are making this a lot more complicated than it is. All one needs is a dummy round to use to throat the chamber where you want it.

Thank you for sticking to the question and not adding peripheral information such as dummy rounds, double rifles, long loadings, alternate cannelures, lighter bullets and in general, making things complicated.

So I ask again with a slight rephrase, any suggestions on who to cut a .458WinMag chamber with a non-standard throat such as what is specified for the .458Lott?

email me with the info I might need. What action/rifle. Can you firnish me a dummy round with the bullet seated where you want it and do you want any free-bore from there? Is the barrel currently chambered for anytyhing?

I believe I can help you out but I need that info.

Jim Ketchum of Jim's precision in Petaluma, California has a IT'S reamer throated exactly like you want. His business phone number is (707)762

3014. If you cut the chamber with a SWAMI spec reamer you are screwed because the throat will be too large in diameter and the leader will be too long. He will tell you all about this reamer if you give him a call.

Good luck,

Blake

JGS. reamer and 3014the is the rest of his phone number.

Blake

Sorry. This phone and I don't always get along.

Blake

Thanks for the lead Blake, I'll get in touch with Jim on the 'morrow.

Have you looked at OAL with the cast bullets you're interested in using? May be able to just chamber as a Lott and use Lott brass. Could trim Lott brass back a little if the OAL is just a bit long, shouldn't be running hot enough loads to erode the chamber if brass is a tad short. May not work if you need to run the canalure right up to the lands tho.
