458 Win Mag - rate of twist - build suggestions

Bored so decided to convert a newly ordered lefty stainless Ruger Hawkeye to .458 Win Mag.
Will never be shooting bullets bigger than 500 grains and doubtful I'll ever go below 400. What rate of twist should I go with?
Plan on ordering a stainless barrel, finished to 22 inches and will glass the action and also install a cross pin in the laminate stock. Will skip installing irons at the present and opt for the 1.5x5 Leupold.

Am I missing anything else? Suggestions are appreciated.


My biggest fear is when I die my wife will sell my guns for what I told her they cost.

It appears that 1 in 14 is the standard and for some mfgs the only twist offered.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

You could go as loose as 18" but the heavier bullets need a twist at least that tight. 20" is too loose IMO for the 500-grainers, especially at longer ranges. I use the 14" and like it a lot.

The 1 in 14" works perfect on my VZ-24 #5 Douglas @22" with 600g & the 500g hornady's I sold you & 450g & 400g & 350g the leupold 1.5X5 is the same scope I have also.
Good Luck!!!! thumb

Seems 1-14 is the way to go. Anyone else build up a 458 on a Ruger before?
Just placed an order for a Shilen stainless #5.

I was looking at the old push feed Ruger 458's and thought a new hawkeye in 458 would be sweet. I just need a deal on one to pop up in my area. I like 20-22" and as light as one could go without it being a mountain rifle. Good luck on the build.
