308 to 358win. ???
How hard is it to do this? Can you just reboar the barrel?

A simple re-bore is all you need to convert a 308 to 358. You will be very happy with a 358. Very underrated little "Thumper"

What rifle? There is a lot to be gained from a bigger case in the 35 caliber; it is fairly anemic based on the 308. Remember you are creating a lighter rifle if you rebore; I always re-barrel and get or make the contour appropriate for the caliber.

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.

A average sporter weight 308 barrel will be quite light if rebored to 358, and there is a chance if there are front sights the screws many be too deep. A better option may be a new barrel.
Nothing wrong with a 358 within it limitations. It is not a long range cartridge but if you do not hunt at long range ........

I dunno...I checked my charts...my velocity was 2425 and my trajectory was:

+2.8 100
0.0 200
-4.5 250
-11.5 300
-21 350 w/1850 fps and 1700+ ft lbs

How many shots do people take at over 350 yds?

I seldom shoot over 200. Your numbers work for me.
But many report much longer shots.
I get asked what to use if a 500+ yard shot is required. I say a better PH.

The 358 Win is a good hunting cartridge, as is the 350 Rem mag [I had one of them once] as well as the 35 Whelen...

However, in todays world of hard to get componets, I would consider keeping a 308 a 308...

Boring & rifling would require hand lapping (I'd hope!). Now, think about why it's advised to trim an inch off the muzzle end of a new blank. And, what's lapping going to do to the throat? For that matter, what throat?! The 'old' throat was "bored" away. There's more to it than just boring and rifling.

The "not so popular stuff" is still available if you look in the right places. .308 is not, anywhere you look. These 'shortages' will eventually pass.

I used to own a push feed Mod 70 Winchester which I rebarrelled to 358 Win with a 20 inch barrel. great little rifle that pointed like a finger and put down big red deer quickly.

I would definitely keep it 20" barrel and focus on getting the balance right.

If the 308 barrel is good then it makes little sense to remove it. Unless that particular rifle is special to you then just sell it or keep it as a back up and buy another rifle chambered for the .358.

Ruger made them recently and so have others.


Get the 'power' or optic that your eye likes instead of what someone else says.

When we go to the doctor they ask us what lens we like!

Do that with your optics.

Make up what you want.
Plenty of 30-06s became 35 Whelens and the bbls seem thick enough.
Whats wrong w/a lighter weight hunting rifle anyway.

I'll second the work at http://www.35caliber.com/

I've had a couple conversions done there by Jessie. One was a 35 on a 303Brit. Excellent work and quick turn around.
He will tell you if the current barrel has dimensions that allow for reboring to 35 cal or not.

If 2400 fps is good, then 2800 will be better, if you go to a 350 Norma. 358 is way too small in case capacity for such a good caliber bullet.

Ill 3rd this gents work, I sent in a .30-06 and it came back a 9.3x62 that shoots wonderful and believe it or not the sights hit the same point of impact so no resighting was needed.

He was fast also.

Sigh. Anything the 308 will do with a 165 gr the 358 can darn near do with a 225. If you compare same style of bullets. A 308 game king has a bc of .401 the 358 gk has a bc of .370. So to 400 yards the ballistics are closer than some load variation of bullet type in a 308 Oh and with 50% higher"energy".

Most people who says "hard kicking" "short range" "weak " have never used one. But will tell you a 35 whelen is great. Federal loads the 35 whelen with 225@2550. I load my 358 with 225@2500. Zero difference in results

Funny you should mention going from 308 to 358. I sent Jesse a barreled action last week to have him do just that.

This will be #4 or #5 that he has done for me. You hear the saying "you can have it good, fast and cheap, pick two", well, with Jesse, you get all three.

I was lucky enough to pick up/find a Model 70 Classic Featherweight in 358 Win. that had been re-barreled using a 22" XX Douglass barrel and the prettiest high gloss deep blue bluing. Picked it up on a consignment sale from a recently widowed woman. Was told her husband passed right after having the rifle built and had just started working up loads for it... even got targets, notes, dies, and various loaded rounds.

The gentleman started with a new Classic Featherweight in 30-06 and used a block in the mag well to accommodate the 358 Win. Suppose his thinking was that if he wasn't happy with the 358 he could re-chamber to 358 Whalen or one of the other various 358's.

It's one of the nicest rifles I have.... wound up removing his Leupold bases and rings and put a Leupold FX3 6x w/Premiere German 4a scope in Talley bases and rings.
