OK. I went into QuickDesign and loaded a 375 RUM and necked it to 458. Loaded it in QL

Hate to admit it but found a pistol I’d hidden when leaving on a quick trip a couple years back.
Knew I had it but couldn’t remember where I hid it. Man.
Was moving some stuff and a mag bonked me on the head.
I kind of went “huh?”
Then I thought “aw man, I remember sticking it up there now”...
Nice deal.
Something about a 30-30. Nostalgia, deer camp and so on. Lot of deer accounted for by that cartridge.
I like Marlins also. I’d have probably walked out with it also. :grin:
Just an FYI in case you need it.
In Winchester’s last brass run there was quite a bit of 300 Savage. You can find it online or pm me and I’ll grab however many you want. I saw some at a local store.
I’d go 30 cal to 284 or 277 then down.
I’d also think about turning the necks to help prevent the bulge.
Ideally you use a 284, 264, then 257 and the gradual drop should help as 350 mentioned.

Matching...
I’ll launch the computer and run it but Benchmark with that bullet will be the ticket. Probably around 24.5 or a little more. Work up.
Give me a few minutes
Here it is a little higher
