9.3 S.A. Wildcat

[sgt_zim]

That would be a sweet cartridge in a ruger no 1, what twist barrel would you suggest for it?

According to Berger, a 14" twist is plenty, even for the very long 320 gr Woodleigh PPSN and the 325 gr Norma Oryx. https://bergerbullets.com/twist-rate-calculator/

Somebody here at AH (can't remember who) has a 9.3x62 with a 12 twist and gets better velocity than the standard 14, or at least better velocity than I'm getting.

And honestly, for a canon like this 9.3 is, the only other bullet I'd use is 300 gr A Frame. Not because I don't think the lighter bullets can take it, but because IMO, heavier is better in most circumstances. If you could push a 300/320/325 gr bullet at 2600+, then why not do it?

Nosler Partition 286 gr: BC .482

FWIW, I was going through my Woodleigh manual this morning, totally forgot they make (made?) a 320 gr PPSN, BC checks in at .457.

At 2600 fps and a 200 yard zero, that only puts you about 9" low at 300 yards. That's a pretty good ballistic arc, and still at 3000 ft-lbs of energy when it gets there.

3000fp at 300yds, now that's knocking the stuffing out of a critter

366 DGW - Cartridge Collector

The 366 DGW was conceived by David G Walker and is based on the 416 Rigby case necked to .366” (9.3mm) and was developed around 2000 by Judson Bailey from The Workshop in St. Albans, ME. It was developed as a hard hitting medium caliber rifle that will still shoot as flat as the Remington […]

I wonder if you can rent reamers for that beast? I do happen to have a no1 action laying around
