what about the 35/358 BR?

[Alan in GA]

anyone done a Whisper in .35 caliber using the BR case? I like .35,,LOTS of bullets to play with,,and the BR case is big enough,,and lots of .308 bolt face rifles out there. I would fit it to my Ruger 77 Mark II switch barrel.
I'm guessing a big problem is: no one has cut quick twists in any .358" bore barrel.
What think?

Hello,
Any barrel maker that does cut rifling, can make a barrel for you in 35 with the twist that you want. I got my 300 whisper barrel from www.border-barrels.com in Scotland.
But you should easily find what you need in the US as well.

Take a look at the 338 Whisper (#1 or first design) it is just a long throated version of the 7 br necked to .338. I Too am a big fan of .357/.358 and called and talked to JD himself. He said he had done about every caliber size he could think of on that case. All worked but he could see no reason to produce them as there was so little diferance. Also the .358 is actually lacking a serious heavy for caliber long slick bullet. the 338 has a factory available bullet (albeit expensive) in the 300 gr sierra Boat tail.

Personally I would love to see you do it ! ( I have a .358 win barrel on a FN/FAL) because I have considered it myself so often.

Hi Guys,
After shooting a 300 Whisper for some time with 240gr MK at sub speeds with a suppressor I soon found out that that bullet BC doesn't matter. Regardless of bullet shape or BC anything past 100yds is going to have a huge drop....like throwing bricks. On game results is like shooting nitting needes unless major bone is hit. Because the bullets don't expand and very rarely tumble.. the only way to get better performance is larger diameter. So a 358 whipser or to my thinking a 375 with a big flat point bullet would be the way to go. I'm toying up bewteen the 375 whipser (I know it will be super accurate) or by using a pistol cartridge like the 45 colt.
To me the 358 or 375 might be the way to go as it will be an improvement on the 300 with neglible increase in sound signature. I'm thinking that a 45 cal bullet flight could be quite noisey with all that frontal area.

I have found out just recently that if you go slow and in small steps ( I went 257 7mm 300 and then 358) that you can get a 223 WSSM up to 358, it looks pretty impressive, though in all honesty I think taking 458 SOCOM brass down would be better and it would at least have a .473 bolt face.

Alan if you are at all interested I am thinking on having a reamer made for this one, shoot me a PM if you are interested in using it ( or maybe even splitting the cost or helping out.... it would sure make my descision easier)

Dang I wish I lived next door to a freindly tool and Die guy.


hmm how many guns now do I have that NO ONE makes ammo for ?
My wife is convinced it is a sickness with no cure

I've got one 358 BFG(WSSM) built now, another barrel on order for the second build.

For what you can pick up the WSSM push feed model 70's right now, its not worth it to me to deal with the feeding issues of the SOCOM's rebated rim in a bolt gun.

As long as you hold to magazine length, the 358 feeds perfectly using the 180 SSP and Nosler 225 BT(the only two I've tried thus far).

No problem exceeding 358 Winchester velocities by bit with a 22" barrel.

I've been stepping up to 8mm and 338 along the way, and annealing at 30 caliber and again at 358 before I turn my necks to .012". Those necks look like hell after necking up(much like the interior of the necks look like on the 223 WSSM factory new brass).
