I am planning and have started the ball rolling on this one. I do not know
of anyone with one, but thought I would build one since I built a 338 federal one way before any one offered it. I got to thinking of a real
hog whapper and I came up with a 358 Winchester with a 250 grn Barnes Cool . I picked up a box of 200 grn Winchester silver tips the other weekend just to look at and said yup Laughing Reamer is ordered, but it may be some time before my
barrel builder can do it for me. Have to order barrel and then run it through the shop inbetween all else. but, I will post some pics when I get it and some pics of the results Laughing Laughing

I had a Contender barrel in .358 once..traded it for a 35Rem because ammo was easier to find at the time..Big Mistake.. Embarassed I liked the 35Rem OK, but it didn't shoot as well as the .358..That thing was fun to shoot, and accurate to boot!
Good luck with the build, and keep us updated....
Yeah...358 Rolling Eyes ......Maybe that would make a great Hog Buster... Twisted Evil

.358 Win in an AR-10, with a 250 grain Barnes.
OAL limited by magazine and action....will the Barnes end up needing to be
seated pretty deep in the case ? I'm thinking it will.

But, Barnes lists 200 and 225 grain versions, not a 250 grain.
TSX shows 200 & 225 grain.

No 225 grain TTSX, only a 200 grain listed.
Unless the Barnes website is not up to date ?

Yes, could be right. I just looked at the options on several different brands
of bullets. I was for sure the 200 grn barnes the 250 I was looking at
probably another brand, have to see what I did with my list Laughing
I found it: hornady inter lock 250, Yup may be too long, there is also
a Nosler Part at 250 grn.

I forgot that the .358 was too long for the AR-15 platform...I did like the 250gr .35 Rem, but there again...Too long Sad
I think a .35cal AR would be cool, but don't want to go to the larger platform.. Rolling Eyes

The .358 Win is a great cartridge. (Of course it is, I own one.) Mine is in a 600 Remington action, 20" Douglas barrel and low-power scope, It also has a limited cartridge length.

The animals I have killed with it have never complained about the length limit imposed by the short 600 action.

Dunno if you use Barnes bullets in it. Thing is, they are longer than conventional
lead core bullets. Since over all length is limited in the AR-10 also, a bullet might
have to be seated too deep in the case before it could feed through the action.
Probably why Barnes doesn't have a 250 grain TSX.
Then again, you don't need as heavy a bullet if it's a mono-metal type.
When sniper started the thread, he mentioned a 250 grain Barnes, and my first
thought was it would be too long. If they made it, it would likely work in a
.35 Whelen though.

Anyway, that was the cause and context of the "too long" remarks.

sounds cool, haven't seen one, these guys have done it:

http://www.ar-10-rifles.com/index.php

according to their site:
"Here are a few available calibers we offer for the AR 10 conversions.

243 Win, 260Rem, 7mm-08, 284Win, 308Win "Match", 35Rem, 300Savage, 257Roberts, 358Win, 300SAUM, 325WSM, 6.5 Creedmore, & more!"


I have a chance right now to buy a 6.5 Creedmoor, complete DPMS gun that one of their team shooters has, not sure if I do or not, have to look at it first

A guy I met at the gun club is going to convert one of those A-10's into a .243. I tried to to talk him into 6.8 but he likes the availability of .243, he wants to be able to walk into any store that sells ammo and get his bullets.

Have to admit that the bigger bullets are intriguing Very Happy

Nice to wack 'em hard! Twisted Evil

On an AR-10, Why not stick with the .308 vs. converting to a .243?

Wide selection and availability of ammo for .308.
Better ballistics with the .308.
Depending on the grain, the velocity is about the same but the .308 has greater energy.
Gun will weigh the about same.
.243 Upper may cost more, not as common as the .308.

Maybe less felt recoil in a .243 vs .308. But in an AR format, .308's recoil is nothing..

you can walk in to most stores now and pick up 6.8 ammo. The .243 isn't that much faster than a 6.8, so I wouldn't bother with a .243, the weight of the AR10 platform is waaaaayyyyyy heavier than the standard AR platform

The guy didn't want the kick of the .308 and hunts out in West Texas, where it's hard to find 6.8. I tried to talk him into 6.8 and possibly reloading it but he wasn't interested.

Once I am sighted it I use only that same ammo and cannot walk into any store to get it, no matter what it is. I have had different ammo with a vast difference in point of impact from different mfg's, less difference with different lots of the same ammo. That is why I buy enough ammo not to run out unless I resight in. Some people are funny about things like your friend is.

I went on a hunt one time with some game wardens. I took 200 rounds of handloads for my tack-driving ultralight .243. I'll be darned if those game wardens didn't enjoy the little gun so much they went through all of my handloads and we finished the hunt using the first store-bought .243 ammo the little gun digested.
