.358 BR

Just a matter of which expander mandrel you use, right? I will say that I have several benchrest buddies who have built 30BR deer rifles, and they say that 30BR with a 125 BT & a case full of H4198 is a deer's worst nightmare, so why not go that way & save yourself all the development work?

For use in a rifle in Indiana the minimum bullet diameter is .357 and the maximum case length is 1.8"
Their original intentions were to allow "pistol" calibers in rifles. They however included the verbage (I'm paraphrasing) that as long as you meet the minimum bullet diameter and stay under the max case length that a wildcat chambering would also be legal.
The 358 WSSM is the hot ticket in Indiana....2nd from left

Howdy !
I'm a fan of the smaller / mid-capacity .35 cal cases. It seems to me, that they should be a viable choice for " score " shoots.
Tried the .357Mag & .357Max in rifles ( " carbines " ), and also .357AutoMag & .35 Remington in an accuracy environment.
I've long considered the .357AutoMag to dimensionally-be a near " .35BR ". There's not a whole buncha difference in the two.
* I ran my " .357AutoMAg " as a 22" barreled benchrest rifle, but..... in .358" caliber. *
IMHO - One would have to really want a " BR " case necked-up to .358" cal, to go to any additional expense to have one
over & above the .357AutoMag ran as .358" caliber ( barrel / bullets ). You're basically talking a .358" cal wildcat here, and
.357AutoMag is already a known quantity; w/ available reamers.
But, " let me say THIS about THAT ":
IMHO - a "BR" capacity case is NOT representative of the " ideal case capacity " for every/all common calibres.
More specifically..... a notional ".35BR " is NOT representative of " ideal case capacity " for .358" calibre.
The " Indiana Deer " cases have been sized to attain a very specific set of allowable dimensions, w/ a .35 cal case.
Their attainable ballistics ( internal/external ) are what they are, in result. Those .35 caliber cases have not of themselves been designed to provide " ideal capacity " for .35 cal case. This is no indictment of their design... I'm only stating the realities.
And while you don't have-to-have a case w/ " ideal case capacity " characteristics in-order to be effective, use of such cases can make a positive contribution to the overall accuracy capability of your rifle/ammo combination.
Ackley's 2 volumne treatise covers things like " ideal case capacity" and "ideal bore capacity ".... amongst many other internal ballistics items. It's fer sher I could not hope to explain such topics anywherez near as well as Ackley did. I recommend a thorough read.
Having tried a variety of .35cal cases in a variety of firearms, I'll say this:
IMHO - .35 Remington provides pretty much " ideal case capacity " for .358" cal . That's a bold thing to say, at a time when Remington
is pretty much whole-sale abandoning provision of .35Rem proprietary brass; for the reloader's use.
One might be tempted to ask: .... "If it's so accurate... why are they quitting the .35 Rem reloading components market "... ?
But let's remember.... .35Rem made its name in the deer fields of America, and to a lesser degree... within the " Metallic Sillhoutte " shooting discipline. And even for the latter, one did not absolutely have-to-have true " BR-level " accuracy. In the end, there's few people
clamoring for the continued availability of Rem-brand .35 Rem brass; so that they can shoot "bench rest style " with it. Excepting me.
My point:
.35 Rem had not been wide-scale trialed as a " bench rest " round, in a bench rest-quality rifle. In consequence, many will jeer at the suggestion of using .35Rem as a hyper-accuracy case/cartridge. It's not an application they envision for the round .
That does not mean my assurances are fundimentally wrong.
I've made a concerted effort to determine the level of best accuracy obtainable w/ a lever-action'ed .35 Rem ( Marlin M-336 XLR ),
and the results have been most gratifying ( see sample pics ).
FWIW -
I whole-heartedly recommend use of the .35Rem case, for shooter intent on shooting .35 cal for things like short-range benchrest or "score" shoots; when shooting that chambering in a true " bench rest-level " rifle; and using bench rest type of ammo prep measures.

I also have an automag in a rifle running 358 bullets, but I have often wondered if you ran the automag reamer long, would you end up with something like a 358 BRX or would the case taper be too great? This might give you an extra 200 fps. The automag .250 neck length is what they are using in the shorter neck length 30BRX
