358 Winchester custom rifle build

The old .35 Winchester, chambered in the 1895 Winchester, is a near ballistic twin to the .358 Winchester. The former developed quite a reputation in the mountain west for game back in the day.

I've been trying to figure out how to build the lightest weight AR-10 chambered for the .358 Winchester. For sub 300 yards it might be a hoot in dense timber.

It's the lightweight (7ish pounds all in) part that makes that difficult and probably impractical. Lol.
 
I like your cartridge choice and have used same years ago but now using 338Fed. I have a different rifle on Defiance Action and would be skeptical if using it for our long, remote hunts here in AK as the tolerances don't allow for dirt etc.

Wilson combat makes a 7lb 358win ar10.
Probably could put some carbon bits on it and drop .5-.75lbs. Would get pretty close.
 
You are correct there is no comparison between a 35 Whelen and a 358 Win. Look at the load data. The top fps in a 358 Win is 2,300/2,400 out of a 23" barrel. Cut that down as far as CAV1/8 is talking about and you are what, 2,100? This would be a fine 150 yard rifle if that is what a fella wants. The 35 Whelen would be substantially more versatile. My 35 Whelen with a 22" barrel is at 2,750fps with 225gr SGKs.
I guess it depends on which bullets you are talking about. My .358 will do 2350 fps with speed 250gr hot cors, 2550 with 225gr sierra game kings, and and 2670fps with 180gr barnes ttsx's. All from a 20" barrel. In like barrel lengths, the whelen is approximately 150-200fps faster than a .358.

Or you could do a 358 or 375 socom in an AR 15. Basically a 35 rem in the AR platform.
 
Great thread going here. I hunt upper Great Lakes big woods, and I love a .358w for the same uses the OP stated. Am also a lefty.

Have a couple of 358s and a couple 35 whelens. The 358's were/are BLR's; still have one and use it regularly. Use a 7600 35W, 18" carbine most frequently for snow tracking.

If the OP wants an accurate, reliable, lefty bolt 358, I'd go Tikka all day with a 1:12. If you're open to other rigs, a 358 BLR is pretty handy.

Just a few weeks ago I dropped a RH 20" Tikka .308 I have as a loaner/for my kids into a KRG echo to shorten up LOP beforing loaning it out to a friend's son. Through confirming zero and carrying it for a day afaild shooting various distances on public ground and tromping around while cutting down a christmas tree, I found it to be exceedingly handy and very quick to shoulder with great scope alignment due to the stock ergos and adjustable comb. I like it so much that I plan to put another together for myself in LH in 6.5 CM, 7mm-08 or .308 with an 18" barrel. Will be a light, rugged rig for quick shots up close or anything out to 600.
 
I am a left handed shooter.

I am looking to build a light, rugged, weather resistant, left handed bolt gun chambered in 358 Winchester.
Preferred to a claw extractor and 3-position safety.
so far I found the Defiance Deviant CRF which is $2,995; it comes with a 3-position safety, a trigger tech special and nitride all included. It also comes in a medium action which peaked my interest even more for handloading/COLE.
if you really want controlled round feed claw extractor + 3 position safety there's only a handful of options that I'm aware of, it'll be more of a hassle for the custom and you gotta want it.

Options I'm aware of when I was looking to custom build CRF guns w/ 3pos safeties: Defiance, Winchester Model 70, Ruger M77, Kimber 84M/84L/8400, Montana 1999, Montana 2022

The only downside to the Deviant bolt carrier is that I will have to have a gunsmith cut the barrel to the action. The Deviant does not have a guaranteed headspace and will not accept pre-fit barrels.
I am not sure if I like that swapping a barrel myself would be an issue.

I don't believe any CRF guns accept pre-fits as all require an extractor cut (with the potential exception of the new montana 2022 but they haven't made any lefties yet?) Seems to put firmly out of the DIY barrel swap to me...


All but defiance would require buying a donor gun. Probably looking for $600-1200 for a donor rifle in one of those which is a fair bit of savings over the $3,000 for defiance.

When I was looking Ruger is by far the most available in left handed models followed by Winchester, then Montana 1999, and Kimber is most likely in last. New montana 2022 no lefties so far.
Weight-wise Dunno about defiance but winchester and ruger are heavy-ish and I think you'd need to try hard to get under 8lb all-in usually looking at 7-7.5# without a scope/rings. Kimbers are pretty light. Montana are about the same as winchester.

Defiance is the only one with a Rem700 footprint so you will have much better selection of stocks, rings, magazines, etc.

Winchester is probably the next easiest to find a stock for, mcmillan inlets a couple models as does stocky's and hs precision. Montana 1999 I've heard is a winchester clone, I don't know if that extends to inletting and bottom metal.

there's a handful of stocks available for rugers but no particularly light ones. HS precision was about the only composite option I saw when I was looking.

Kimbers are a round bodied action but not a 700 clone. Almost no one inlets for them that I've found except for a couple small makers: pendleton composites, MPI rifle stocks, bansner?
Most kimbers came with a blind magazine for a long time so most used rifles don't come with bottom metal, kimber doesn't sell them, and I never found any aftermarket options when I was looking. Would be a bit of a unicorn to find a LH model with a floorplate. Kimber would sell you a stock once upon a time but you gotta send em your rifle for them to install it.


I just had a custom done on a Winchester model 70. Ended up going with that because the action fit and finish was much nicer than my Ruger and stock options were a bit nicer. I wasn't willing to spend the $$ for a defiance just yet, maybe someday.
 
One can go down the rabbit hole themselves, but it is my understanding that closed top bolt actions, like a Tikka, have actually proven to be more reliable than CRF's.

I have nothing against a CRF and currently own several, but for situations that might require quick follow up shots, I much prefer designs that offer lower bolt throw angles.
