Has anyone had a 375 H&H rebored and chambered to 458 Lott ? I have left a phone message JES regarding this. I think .411 is as big as JES goes? At least, I think that's the largest bore I remember seeing on his website. Maybe he does others by individual request?

His website actually lists the 458 as a rebore option, and “458 Mag” is listed a chamber option.

99.9999999% I've heard great things about JES rebore. However, years ago, I bought a Rem760 from JES that was rebored to 9.3x62. Very cool in theory but I had issues getting it to shoot. Long story short, after multiple factory ammo and reloads, I bought a No GO gauge...... and it chambered. I cant say I know what that means 100% but it spooked me enough to swear-off ever buying or ever having a rebore done or owning one.
That said...I sold the rifle to someone who had more faith than I......and I wish I still had the rifle to continue the detective work.... If that was the case I’d have bet a dollar he would have taken it back, taken a thread off and made it rifle. He did a 35 Newton for me. Had a rough chamber. 2md time around it was perfect though. On a 760 you cant set barrel back you have to get right first time. Bud had Jes rebore a 06 to 35 Whelen and he regrets it.

Ah, you're right about 458. Was looking at the example page. Interesting that he skips 416.

I’d go ahead and rebore a shooter if you’re making something you need, like say an ‘06 into a 9.3.

Pa,
Right on bud. If i called in a 55-70 inch antlered moose, that popped out of the willows head on at 10 yards id rather the rifle be a 1.5 moa 9.3x62 mauser, than a one hole 270 winchester or 06
Then on the upper end of distance im comfortable taking moose, ive had that same 1.5 moa nine-three drop moose and caribou at 400 and 500 yards.

I have a new Weatherby vanguard 223 with a 20" threaded varmint weight barrel that is factory cerekoted Grey. I've thought about having them rebore it to 350 legend so I could use it to shoot heavy subsonic cast bullets. Does the JES process mess up the factory finish much? I'd hate to ruin a brand new cerekote job when I could send in something else instead. I wonder how fast of twist they could do.

Not sure about the finish question, but how fast of a twist are you looking for? There aren't a whole lot of long .355" bullets I know of that would need an especially fast twist, can't imagine needing more than 1/16.

He returned my call. He said that he could rebore the 375 H&H barrel to .458 and chamber to 458 Lott. He did say he would have to rent the reamer for the Lott and that would be a little extra cost. Ah, you're right about 458. Was looking at the example page. Interesting that he skips 416.

I own three and they all shoot great. Be Well, RZ.

I've had 3 done by JES. A CZ from 30-06 to 338-06, an Interarms Mark X from 30-06 to 9.3x62, and a Rem 700 from 30-06 to 9.3x62. No regrets what-so-ever. If ever come across another Ruger 77 tang safety in 30-06 that uses Rem 700 rings and bases and has iron sights, I'll send it off to JES and have him rebore it to 9.3x62.
FWIW, on the last 9.3x62 rebore (Rem 700) I asked Jes to mark the caliber, et al on the underside of the barrel shank rather than stamp X's and remark on an exposed surface. In turn, I milled out the existing caliber marking and had that mill cut engraved with the proper caliber. And I'd never parted with it . . . . . 
I never thought I'd grow up to be a grumpy old man, but I did, and I'm killin' it.

I'm curious if anyone has paid extra for more grooves or just rolled with the standard 3? I haven't, mine have all been 3's. Might try a 4 one of these days, just for the heck of it.

Yes, he certainly seems like a good guy. It was a pleasure talking with him on the phone.

Took it to South Africa in 2013. The PH was impressed with the 210 Sciroccos I was using. Whenever an elk hunt materializes that’s the rifle I’m taking.

I was going to do that just because 4 is "normal", but having tried the 3 I think it may be superior. I shoot A-Frames out of mine (.375 WSM), which tend to be high pressure because it's hard to engrave them into the lands - the partition is too hard to compress. But on this barrel they behaved much more like a cup & core in terms of pressure. I think it's because there's not so many lands and none of them are directly opposed. The partition just doesn't get compressed as much. It's a sample of one, but I got better results than I expected.
