I like the way y’all think. I’m pretty sure I’m in the right group here. I have a .30-06 Winchester M70 I bought at the shop for like $200 about 4 years ago. We don’t specialize in bolt guns, so it’s been in inventory. Thinking of doing a .318 WR with it.

I am leaning real hard on doing a 400 h&h with a Mod 70. Sure, its not a 404, but its pretty unique! Plus that'll give me a 300/375/400 h&h all on M70's!

If you go that route, don’t stop! Finish off with 244 and 275 H&H.

Here's a bull I took with a Model 70 Safari Express. 400 grain bullet at 2300fps. Hmmm sounds just exactly like a 404 J right? The bull even thought it was a 404.
He got back up and ran off when I told him it was a 416 Rem! Haha! :sneaky:

As a lefty that collects/hoards Win M70 classics I know that outside of the custom shop they didn’t chamber any of the RUM rounds in LH Classic actions...those make the best candidates for 404 conversions. So that leaves us having to convert 7 Mag/300 Mag actions or even worse 375 H&H length. I have had a 375 H&H LH Classic converted to 375 RUM and it functions flawlessly so far. It is achievable but there isn’t a long list of gunsmiths that will take it on...just have to find one.

What other lefty Classics do you have? I have only managed to acquire one over the years (am not USA based).

All were left hand CRF New Haven Classics.

7 Rem Mag lefty was opened up and converted to 375 H&H.
My 300 Win was opened up and converted to 458 Lott and should be getting it back this week.
And I converted a 375 H&H Super Express to 375 RUM.

I had CP Donnelly rebarrel a Win 70 Super Grade 338 to 375 RUM and other than the barrel the only thing that was needed was a different follower for it to feed correctly. Did you have a similar experience?

I did not go ahead with the conversion as I still havent located a donor lefty model 70. Lost the auction on the one way back and havent found one since. And I just couldnt stand the idea of converting my 375 H&H. Still on my radar but in the interim I used the funds to upgrade my binos etc to Leica.

Hi Bob, how's things going in Wyong?. Down your way a couple of years back but haven't been in NSW since Ebor for the fishing. just getting over some nasty storms up here in Qld, seeing the sun for the first time in a few days. I'm going to NZ in the spring and hope to clean up a few buns while there and perhaps shake the spiders out of my old .303LE (currently owned by my BIL). Cheers Brian

Did you purchase your hunt at a US SCI fundraiser?

Heard you may have load data for the 500 Jeffery,.....any info would be appreciated. Was thinking 535gr, but already had a response that the 570gr would be a better way to go, not sure why.
